WORKMATES is a series of little passive 0HP modules that offer simple but effective audio and CV processing in conjunction with your modular or semi-modular synth. Note that these are passive modules without any power consumption. As a result, you will have a bit of signal level reduction when patching a WORKMATE within your modular processing chain. Nevertheless these little helpers are very convenient solution providers if you run out of HP. workmates / passive eurorack tools / 0 HP ⇣ WORKMATES is a series of little passive 0HP modules that offer simple but effective audio and CV processing in conjunction with your modular or semi-modular synth. Note that these are passive modules without any power consumption. As a result, you will have a bit of signal level reduction when patching a WORKMATE within your modular processing chain. Nevertheless these little helpers are very convenient solution providers if you run out of HP. They are also the easiest way to learn SMD soldering. Practice your soldering skills without any fear of shorts and magic smoke. passat PASSAT is a fully passive 4-channel attenuator featuring four smooth sliders for intuitive level control. Each input has its own dedicated slider, allowing you to reduce the signal level by moving the slider downward. At the lowest position, no signal is sent to the output. At the highest position, the input signal is passed through unchanged. Input 1 is internally normalized to inputs 2–4. If no cable is connected to inputs 2–4, the signal from input 1 is automatically routed to those channels. This allows PASSAT to act as a simple passive signal multiple with individual attenuation per channel. As a completely passive design, PASSAT requires no power and does not consume any of your precious case HP. It is an ideal utility for controlling multiple audio or CV sources from a single point. Use PASSAT to attenuate Eurorack audio signals to line level, mix multiple CV sources, or precisely scale control voltages for sensitive module inputs. pix PIX is a passive mixer with 3 stereo inputs and 1 stereo output. Each channel has its own volume control and tilt EQ. With the EQ you can emphasize either low or high frequencies. Due to its passive design, a very compact format could be realized, with dimensions of only 55mm x 65mm. It was designed for use with modular level inputs, which are further processed by line-level devices with volume amplification. You can also use this mixer with line-level synthesizers, but you will lose quite a bit of volume. If too much gain is then used in the downstream processing chain, the noise floor can be raised to an uncomfortable level. Nevertheless, PIX has been used successfully with line-level signals. It has an input impedance of around 1.2kΩ at 1kHz. PIX is your solution for compact mixing requirements in a mobile modular setup. split Splits MIC MONO INPUT and STEREO OUTPUT signals to individual jacks from TRRS Combo Jack. The microphone input has a level potentiometer. Ideal for easy sampling and mixing with devices like OP-Z or tablets. touch TOUCH is a passive, touch-sensitive attenuator. Any signal applied to the input jack passes through your skin to the output jack. Depending on the amount of pressure and the moisture of your finger, the resistance decreases, allowing a larger portion of the signal to pass through. trs switch TRS MIDI type A to/from TRS MIDI type B adapter. Swaps the tip and ring of a 3.5mm stereo jack. Ideal for connecting TRS MIDI devices with different TRS MIDI standards (e.g. Novation device with KORG device). lpg LPG is a passive vactrol based low pass gate. It also has a passive low pass filter for subtle tone control. By choosing different kind of vactrols you will achieve contrasting kind of gate responses, from lush and slow to very fast and snappy. clipping cat CLIPPING CAT is a passive distortion that can blend between hard clipping crossover distortion and softened LED clipping that is only applied to negative peaks of the signal. Hence you can control the type of distortion from harsh clipping to a rather subtle distortion with more even order harmonics. “Clipping Cat” will wink if you turn the potentiometer counter-clockwise for softened distortion and will stare at you with both eyes turning it clockwise for harsh clipping. Clipping Cat is also availbable as an active 3U module! swap SWAP exchanges the destination of one or two sources (audio or CV) with the push of a button. This way you can route two different signals to the corresponding destination of the other input or route one signal to either one of two patch cables. You may also use it as a simple on/off switch. There might be audible clicks when using it to swap/switch audio. combiner COMBINER is either a 4 to 1 Passive Mixer, an or-wired Trigger/Gate Combiner or a 1 to 4 Passive Mult. Before soldering you have to decide which functionality you prefer. If you solder resistors you will get a four-channel mixer and if you solder diodes you will have a trigger/gate combiner. For a Passive Mult you just need to short the pads mentioned in the BOM. eq EQ is a one knob low and high frequency EQ with mid frequency range control. Turning the knob counter-clockwise will filter out frequencies above 1kHz and turning it clockwise will filter out frequencies below 1kHz. Not filtered frequencies are emphasized a bit to have a sharper sound when lower frequencies are filtered and to have more bass when higher frequencies are filtered. The little mid frequency range knob moves the cutoff range around 1kHz and changes how much the not filtered frequencies are emphasized. attenuator ATT is a simple attenuator that allows level control over CV or audio signals. If you want to use it for audio and you don´t have a logarithmic pot at hand, you have the option to use a linear potentiometer and solder an additional resistor for a fake logarithmic response. videos Up

Oscillator alstaden / analog waveshaping oscillator / 16 HP ⇣ ALSTADEN is your source for harsh and harmonically rich sounds. It is a newly developed waveshaping tone generator and resembles the secondary oscillator of the semi-modular synthesizer „EUPHORIA“. 1/3 key features Analog Oscillator with 5 Waveforms CV Waveshaper and VCA EQ and External Inputs Level-Potentiometers Linear and Exponential FM specs & downloads width: 16 HP depth: 30 mm power: 75 mA @ +12V / 65 mA @ -12V documentation videos description / manual The waves are formed by a combination of diode clipping and folding of the waveform by adding mirror images of the upper and lower parts of the waveform. This creates more high harmonics and interesting timbral variations. It also features an equalizer, which is quite unusual for oscillators, but offers more sonic possibilities. The oscillator module offers five different waveforms WAVE A, WAVE B, PULSE, SUB and SINE. The level of the individual waveforms can be adjusted with sliding potentiometers. The range of the levels depends mainly on the gain you set during calibration. Distortion can easily occur in the upper positions of the sliders if you have set the gain high. The pulse width of the PULSE waveform can be changed manually with the PULSE PWM knob. There is also a CV input CV PWM with its own attenuator to control the pulse width via CV. At the heart of this oscillator are the two waveshapers WAVE A and WAVE B. Harmonics are added by wavefolding and can be changed by turning the SHAPE A and SHAPE B knobs. Additionally there is a CV input CV SHAPE A1 and CV SHAPE B1 with an attenuator each for voltage controlled wave folding. WAVE B has a second CV input without attenuator that allows even more control over the wavefolding state. The SUBOCTAVE has two stages of -1 and -2 octaves. Select your preferred division with the help of the SUB -1 and SUB -2 on/off switches. Unexpectedly, you can equalize the output of the oscillator with the TONE control. It accentuates either low or high frequencies of all waveforms before they are fed to a internal VCA. The INTERNAL VCA can be controlled via the ENV IN socket. Patch any CV here to change the level of the main output. Additionally, there is also a FM input. You can apply exponential or linear FM by feeding any (preferably high frequency) voltage into the FM input. Select an FM type with the EXP/LIN switch. If you set the switch to the middle position, no FM will be applied. V/OCT is the input for the application of a pitch CV. The pitch can be controlled manually with the PITCH and FINE potentiometers. EXT IN A and EXT IN B are audio inputs that allow you to use the oscillator as a waveshaper for external signals. When a jack is connected to these inputs, the corresponding internal waveform is switched off. The external signals will also be routed through the level potentiometers, EQ and VCA.

Oscillator cinco / five oscillators in a module / 14 HP ⇣ CINCO consists of a series of five oscillators that can be controlled in pitch from a single source. It generates drones, chords and massive walls of sound that stand out impressively from classic single-wave oscillators. 1/3 key features Five Analog Oscillators 2x Saw or Pulse and 3x Saw Waves Individual Pitch Controls Single CV Pitch Input Transpose all Oscillators Internal Mixer Individual Outputs Pulse Width Control (OSC 1 & 2) FM Inputs (OSC 3, 4 & 5) Skiff friendly Wrong polarity protection specs & downloads width: 14 HP depth: 30 mm power: 65 mA @ +12V / 43 mA @ -12V documentation videos description / manual Cinco boasts five analog oscillators capable of generating drones or chords comprising five notes, accessible from the MIX OUT socket. Each oscillator's tuning can be adjusted independently using the TUNE and FINE controls. Simultaneous pitch control for all five oscillators is facilitated by patching CV to the CV ALL input. Moreover, the TUNE ALL knob allows for collective transposition of all oscillators, with the range of transpose amount adjustable via a trimmer located on the module's rear. While Cinco wasn't specifically designed for precise 1V per octave tracking, you can achieve close approximation by calibrating tuning using trimmers located on the module's back. The first oscillator is slightly tuned below the rest, while the last oscillator is slightly tuned above. The fixed oscillator tuning can be changed with optional capacitors on the circuit board. Oscillators 1 and 2 offer a choice between a SAW or PULSE waveform, each selectable via dedicated toggle switches. Pulse width adjustment can be done manually using the PLS WIDTH knobs or via CV modulation. In the case of CV modulation, the PWM knob controls the intensity of the modulation. It's important to note that these PWM knobs aren't attenuators; hence, incoming CV cannot be completely deactivated for pulse width control but can be reduced to a pleasant level. Oscillators 3 to 5 exclusively output a saw waveform and include additional frequency modulation inputs (FM IN). Applying voltage to these inputs modulates the frequency (pitch) of the oscillators. The FM AMT controls determine the degree of CV influence on the frequency. Similar to previous controls, the FM AMT knobs aren't attenuators, meaning full left rotation won't completely eliminate FM, but rather reduce it to a minimal level. Notably, the FM IN input of oscillator 3 is normalized to the other FM inputs. This facilitates pitch control for oscillators 3 to 5 alongside the primary CV ALL pitch input. If desired, this normalization can be disabled by desoldering an SMD bridge located on the back of the PCB or by connecting dummy cables (patch cables that are not connected further) to the other FM inputs. Utilize the five LEVEL controls to precisely adjust the volume of each oscillator or completely deactivate them by turning the controls fully counterclockwise. Additionally, each oscillator is individually outputted via the OUT sockets located at the bottom, allowing for further isolated processing of the signals with external modules. Importantly, these individual outputs are not affected by the LEVEL controls and typically produce louder signals compared to the mixed output. Cinco isn't just a source for rich and harmonically versatile analog sounds; it's also capable of generating harsh and earthshaking waveforms, particularly when utilizing the FM inputs.

MOONCAKE Catalogue No.: ST015 Mooncake is a versatile release that moves stylistically between house, deep house and downbeat. Each of the tracks has its own unique character and sets itself apart from the other tracks on the release. „Call me Maybe“ is a forward moving house track that carries through a rolling bassline and floating lead sounds. Classic percussion and well staged breaks are framed by vocal-like pads. „Millennium“ is a classic deep house track with smooth chords and pads. Driving rides underline the sounds and tempt you to tap your foot.„She Said“ follows in the same footsteps and treats the listener with ear candy in every minute. A perfect piece to look out the window while driving. „Obscurity Stars“ has a melancholic character, but does not forget to spice melancholy with a good portion of groove. FM bass sounds meet saxophone pads, rounded off with rarely heard vocal sounds, a great listening experience. The last track called "Luck of the Edge" has equally melancholic qualities, but knows how to break them up with its downbeat-like framework. Interesting vocals, beautiful pads and well-tempered chords form a varied and unique arrangement. Get your copy! Stream on Spotify! OSTINATO MODULARE Catalogue No.: ST014 Ostinato Modulare is a collection of modular blueprints, that captivate the listener through repetition and dynamics. It creates its energy as part of the essence of becoming to run in two directions at the same time - the direction of constancy and that of change. This collection, exclusively created with modular or semi-modular synthesizers, does not allow distance and is associated with cognitive insight and far-sighted incomparability. It shows the metaphysical perception that not all pieces of music of the modern modular age are of the same nature and kind, which offers a subtle consolation to the listener. Thus, unlike language, musical expression is not just a convention that has become socially anchored over time and shaped into supposed certainties, but is an expression of true moments and feelings without caring about a certain order. “Music breaks out again and again, forms new structures, it mutates and creates new connections, which nevertheless can always be understood immediately”, Stefan Tretau once said. Hence, with transfigured restraint and withdrawn loudness he has designed an antipole to the omnipresent anger of our times, giving the listener the opportunity to withdraw into an imaginary aviary, at least for a short period of time. Get your copy! Stream on Spotify! MIND WORKS Catalogue No.: ST013 Mind Works is a very versatile mini album presenting seven very different tracks from pounding techno to ambient melodies. "Reat" is the beginning and presents itself as a minimal, but impelling techno track that cuts a fine figure on every dance floor. Rolling hats, dark tones and a functional arrangement are the tools for a functional techno track adventure. More dignified and groovy "Mori" continues the album with its very own style. Swinging hats, tribal percussion and housy notes convey a sense of infinity. "Robab", on the other hand, conveys a mysterious mood. Freely floating jazzy sounds and unique percussions carry the listener through a small electronic world of experiences. A piece that sets interesting accents without drifting into the ridiculous. "Lative" begins with a pounding attitude, but unfolds a hypnotic depth that fits wonderfully to passing landscapes. "Itle" lives from a very harsh sounding bassline that works its way through the track. It never stops being waving and meandering keeping the listeners ears busy in every state. In contrast to that pleasant-sounding pad sounds dissolve themselves in an ambivalent atmosphere that's hard to describe. Lovely and incredibly groovy "Bina" heralds the quiet end of the album. The rhythm of the bass line never seems to be static and is part of the organic foundation on which the song is built on. Hypnotic piano sounda and a warming melody in the middle section make this piece a matter of the heart. "Unive" is a melody recording of a modular system. There is no fixed arrangement, no post-production, only raw analogue sounds with all their facets and peculiarities. Here Stefan mainly uses sound generators that he has built himself under his ST Modular imprint creating a piece of loveliness that is hard to beat. Get your copy! Stream on Spotify! DIVIDING OUR GRIEF Catalogue No.: ST012 Stefan Tretau returns with his first release in 2016 presenting a very versatile EP on his own label ST Records. Including banging techno tracks and tech-house beats as well as melodic downbeat and experimental-chillout, this release invites you to a sonic adventure. This adventure, however, does not want to be experienced only for the duration of a moment, but asks for a concentration on the ongoing moment. This continuous recurring flow of the specific and unforeseen is the starting point of this EP. Thanks to its catchy rhythm and functional character “Purified Content" makes it easier for the listener to enter a timepiece that is comparable to the rhythm demanding entry into a musical night. It is "Interference on the Rebound" that continues with a merger of the inner world. It sets the world or rather perceives it as reality itself and makes the flowing movement not only to an abstract moment, but a period of time. "Particles" presupposes an awareness of the present´s transience. If you let your inner eye look out of the window you may see the guide posts at an rhythmic interval just as if they had divided our time into units. A track that pushes the possibility of all events completely into the background. “Staring at Histerics" is like a reversed blueprint of our restless present time. Like a solution this track focusses on the physicality and spatiality of the listener, until the organical crackling ending finds a milieu-like transition to the world-closing track "Bijou". Here it dissolves itself, the resonance between the subject and the world, and you may hope to completely escape from the current acceleratorism with its feasible fantasies. Get your copy! Stream on Spotify! RADICAL Catalogue No.: ST011 Perhaps "Radical" is the best name for Stefan's first EP in 2015. And that´s just because the style of this publication has changed radically in contrast to his previous releases. Driving beats and rolling synth-sounds move these tracks to the edge of a techno moment. Furnished with chords and melodic moments the first track "Radical" takes the lead. At the beginning this piece doesnt show what will evolve with time. Because in the middle of the track each foot will feel the beat and wants to move on, just to keep pounding with a big grin after the break. "Dissolving" is defined by its straight-driving beat, its grinding sounds and melodic accompaniment as a perfect tool for Dj-use. No innovation award is expected here and no revolution is born, because "Dissolving" just wants to live up to one´s name and dissolve in a mix to be part of a whole. Chords, again Chords, a bit of reverb and much delay - these are the ingredients that make the third title of this EP to a melancholic deep house track. Almost ten minutes seem to be much at first, but in the course of the track this length arises to be a perfect base to mindlessly getting lost in it. "Lacidar” marches to a different drummer. Being less impulsive, but more funky and cozily here, this track provides a melody, which will surely cause earwigs. Get your copy! Stream on Spotify! CHIVVY Catalogue No.: ST010 It seems that Stefan Tretau has renounced his past. Parallel to his last release "Set your Mind to Control the Heart of the Sun" his new mini-album "Chivvy" moves again off the beaten track. However, it turns out to be less analog and abstract than the previous album. You may call it crackling-jazzy and floating-melodic, if you want to describe music at all. It seems that a classic house track is not essential for the success of a new release. Ease and melody are his new fashion. Even if this fashion is only a temporary equalization of taste and it will probably not last for too long. He believes lack of imagination to exploit new opportunities is not an option. Only with imagination can he accept the new, rebel against the old, leave the familiar behind and transform the common to the unknown. For Stefan it is impossible to set his own limits a priori. They must be recognized, experienced and perceived. Even if his constant search does not have the goal to enhance the music. At least it satisfies his desire for roots and origin and paves his way forward. Future needs origin, even if it means to reverse the slowness of the origin and the rapidity of the future. Only cessation leads to consciousness. Finally "Chivvy" is not only an expression of an inner trait, but it is a hunt for musical backgrounds. Get your copy! Stream on Spotify! SET YOUR MIND TO CONTROL THE HEART OF THE SUN Catalogue No.: ST09 Releasing his new album "Set your Mind to Control the Heart of the Sun" Stefan Tretau explores the subtlety of abstract sounds without any climax and insistence, just for its own sake and the effect of a musical time as a whole. Recently Stefan Tretau feels most comfortable apart from the club-context. Being a forward-thinking producer he is rather interested in the experience of music making and active listening than dance floors with flash lights. A successful development, but also a risky encroachment into the niche. The very first track of the album "Sparks in Ray of Light" sounds like the sun as a symbol of life, the origin of beings and not least as joy of the day and beauty of the sky. It is a shallow kick off with soundscapes and drone sounds, but it also reflects the strength and tightness of rays of sunlight. With the help of musical pleasantness and classical instruments the next three pieces "Lost in a Molecular Cloud", "Luminosity for a Few" and "Contrasting Tendencies" fill the room with the same zestfulness consequentially. Just after this smooth introduction "Substance Necessary" acts as a wake-up call from the happy depth. Its linear and stomping beat walks straight into the rhythm of alleged shady sides. "Fifth Ray of Neve" shows Stefan´s origins and presents itself as a classic deep house track. Supported by pretty chord sounds and analog sound effects it prepares the listener for the most mainstream capable title of the album. Equipped with a vocal, a break in the middle, a solid beat and all that goes with it "The New Solar Silence" spreads a solid tech house atmosphere. But Stefan dares not to return to the club too much as "Corona's Flare" and "Ulysses sample" already explore the vastness of jazzy-analog swing again. Rarely heard sounds and a lot of details keep the tension taut, just until the penultimate appearance of "Sun Soul Supreme" rises up into the basement of the next electronica jazz club. Here you will also find "Faintly Sweet" with its intangible abstract patterns and vivid sounds – a truly abstract ending. This release is not easy, it's versatile, detailed, constant and shallow, but also powerful and abstract. It needs time to listen and a slow approach to get your mind accustomed to it, just like your eyes to the light of the sun. Get your copy! Stream on Spotify! RISE UP Catalogue No.: ST08 Less weight, more playfulness, less deepness, more house - perhaps that was Stefan Tretau's intention with his latest EP "Rise Up" on ST_Records. According to the season ST008 rather shines with swinging basslines and cheerful head-banging rhythms, instead of profound chords and pads. "Rise Up" sounds like a wake-up call, an invitation to move. The groovy bassline exudes a direct funk that is pollinated by chords and melodies. In the break a whole swarm of sounds effuses just looking for the best house nectar, only to await the sweet juice of the next perennial in the last part of the track. Even with "Orange Blossom" the piece is carried by the bassline. Slightly stomping and singing with the accompaniment of a thousand-marching bees the strings prepare the listener to the underlying irony of the track, that is being confirmed by the easiness of the melody until the last bar. Oldskoolish and moody “Buckwheat" starts off. The funky carved up 303 Bassline hatches out of its honeycomb in the middle of the song and unfolds its beauty extensively in the contrary held break. Playful and fresh the track leads the swarm to the peripheral areas of any acid moments. Get your copy! Stream on Spotify! LOVE, LORE, LOWLINESS Catalogue No.: ST07 Three words whose meaning do not have a high reputation nowadays. People seem to be too much influenced by the ubiquitous fast pace, the media omnipresence of the incomprehension and chronic overconfidence. Love Lore Lowliness is criticising the hedonistic crowd by snapshots of works and polaroids of silence without being sentimental, and as a sideffect, it shows Stefan Tretau's versatility on ST Records. [LOVE] Love is generally known as the strongest feeling of affection and esteem a person can place in another. A state of intimate posture and deep connection that transcends any particular purpose or use. A feeling that is not only met with people, but also things and actions. Love is an explanation of action in full surrender, continuously and over again, regardless of the appreciation obtained. [LORE] The knowledge to understand things and then aligning his action according to it doesnt come out of the blue. It needs some effort you will find this lore as a pay check in the decision fundus. The expectation to get, control and dominate without much struggle is the biggest obstacle - not the perfection of knowledge is important, but the confrontation with the challenge. Whereby also languishing ignorance is a chance for the unexpected. [LOWLINESS] Humility is not the misunderstanding of the submission to the Lord. Without denying this, the term has more useful meanings: humility and the realization that you will not always reach the goal first. Lack of humility and lack of self-confidence to show humility are a breeding ground for disaffection and assault. Only the one who lowers his head once, sees the floor, carrying him constantly. [ALBUM] Whether you are transferring these words directly or indirectly on the album and it´s music, is up to each individual. Regardless of this it becomes clear what is the reason for doing such a work: the love of music creation, the motivation to learn new and the serenity that it will be hardly heard by anyone. Get your copy! Stream on Spotify! POLES APART Catalogue No.: ST06 Nothing on earth can be further apart from each other than our poles. Also ST006 takes us to distant worlds, abstract landscapes and deep voyages. Therefore "Poles Apart" is the name of Stefan Tretau´s latest EP on ST_Records and it´s a must for any deep-house-hedonist. The best way to enjoy electronic music is to completely lose yourself in it. With "Poles Apart" that succeeds from the very first minute. Delay dipped Chords continually flow against the incipient beat and let the listener worlds back away. Almost technoid and with rustling hats the second track "Into the Past" starts off. Deep-sounding, almost scratchy chords set up where Poles Apart left off. In this case, the piece remains extremely straightforward and definable, but without losing any tension. "Constancy of Purpose" is like the moment where you fly slowly over a large glacier. Floating and with continuous rhythm ice flies by and one hardly noticed how the flashing percussion describe a size that is only evident at a second glance. "Edge" sounds like cuddling ice floes. Pleasant melodies are accompanied by cracking ice sheets, ice rain pattering follow footstep-like hats and backward-moving pad sounds complete the subtle arrangement that acts as the conclusion of a caressing circular motion. Apparently from another end of the world is "Bugs". With its LFO-pitched bass drum, the staccato guitar sounds, the blips and opening hats, this sound seems like a still unknown arctic being who courts for further attention with its dry and direct bass sounds.

To answer this question Stefan Mallmann 's original crustacean was put through the mill three times on the fifth publication on ST_Records. The original is not at the beginning, because at the end it becomes a real shrimp. So it´s Mallmann 's "Van de Merwe" edit starting with cheerful deep house and walking jauntily into the chord district. Droning vocals that sound like alien calls may be the only reason why you should not freely enjoy the South African sun. Tretau 's "MNU" elaboration appears to be dancing in a square, barely escaping from shearing attacks. Being snappy and percussive this track remains in tech house laboratory and fetches one shrimp after another out of the slum. Slightly metallic and sounding like junkyard stomps, Tretau 's "No Human" remix jumps straight into the battle suit. Technoid sounds and a continuous beat are literally searching for new fuel to fly the shrimp-flight-module. Mallmann 's “Original” has been through all transformations and is finally mutated to the real shrimp. With driving bongo and conga hits, a subtle techouse-crust and distinctive shrimp calls this piece appears to be the mothership on the way to it´s home planet. Get your copy! Stream on Spotify! ALTERNATIVES TO SINGULARITY Catalogue No.: ST04 Following his last album success "Yesterday you said tomorrow" on Broque Records in 2011 Stefan Tretau now presents the next album release on his own label ST_Records. "Alternatives to Singularity" is not a logical continuation of his previous work, but rather an evolution and resolution of old structures. Therefore you will miss straight forward beats and the known Tretau-Arragements at first, but instead you get a wonderful mix of Electronica, glitchy Dubstep, Breakbeat and classic Deep House. Nevertheless, despite of Stefan´s temporary reorientation he remains true to himself and carries on combining deep sounds with catchy melodies. As a result, the bassline in the frist track "Hacked Japanese Toilet" is mixed with the moving sounds of the topic to such an extend, that you can hardly escape from its ease and playfulness. Despite of the unabashed beat-framework, the light-heartedness of a summer walk also dominates in the following tracks "How soon is now" and "Lake on to Iceland". "Last Soliloquy" surprises with a classical drum´n bass presentation and releases its happiness thru wonderfully staged guitar recordings, just before "Pencil Nunchakus" jazzy rhythm is floating down the slope like a rich river. With "River as Seen" and "Now Hangs Framed" Stefan then moved back again to his roots. He easily fades from playful rhodes house to dubby deep house. Rhythmically straight and packed with melancholia "Locomotive in Lodz" then opens the last third of the album, where "Digital Dementia" builds a source of recognition values by its unusual sounds. Finally, "Curiosity Sings" is not only the last track of the album, but also a remarkable conclusion that stays as a reminder of good times in your memory. Get your copy! Stream on Spotify! COME ON OVER Catalogue No.: ST03 Stefan Tretau strengthens the reactivation of his label with his third release on ST_Records. "Come on Over" is the newest EP and it comes over with a melodic-deephouse-inside underneath its techhouse-coat. "Come On Over" spreads with an expecting attitude, an unsealed anticipation for something forthcoming. Despite the deeper chords this track takes shape of a cheerful figure using airy piano sounds and a mellow melody. Surly a piece one can hardly escape from. The "Come On Over Miles Deluxe Remix" goes a step further than the original and highlights the excitement with a challenging groove. Miles combines deep chords with a bouncing counterpart, just to break the suspense with the aid of an atmospheric surprise in the last third. Great! „Through Changes" knows how to present its qualities with a simple groove and keeps his retro-look until the last beat. A perfectly staged rim shot in the first and deep synthsounds in the second half make this tune become a true runner! Being set free and coming with a rolling bassline "Choose To See" highlights the auspicious character of this EP. A delay-covered vocal, raindropping mallet-percussions and a simple melody leave this piece to be a warm welcomed partner for your ears. „Inside Of An Atom" explores the nature of dubtechno and chillout using simple chords, wide spread guitar licks and delayed percussion. This track maintains its fluffy and poetic touch and may leave you stranded a million miles from where you began. Get your copy! Stream on Spotify! HIGH WAYS Catalogue No.: ST02 The first MP3-EP coming under my own direction is now available. It includes a healthy mixture of deep and tech-house tunes and crows with impulsive and dreamy beats. Like a lonley ride "High Ways" unfolds its hypnotic impact. Immeditaly you try to syncronize the beat to the passing road markings. Lovely melodies and effect covered tones in the first and almost floating synthsounds in the second part of the track bypass like landmarks on the roadside. A truly melodic track that keeps one moving. "Daniel Doppler" has chosen a roadster for his High Ways Remix. Being almost unstoppable, this beatengine keeps running straight towards its intention. Daniel uses the original´s samples in a descreet, but recognizable manner. During the break it feels like cruising towards the rising sun, just to push the gas pedal in the field of electronics immediatley afterwards. Truly the most racy track on this ep! "The Best Is Yet To Come", what a promise! Due to its frisky character and underlying funk this track seem to contest its title itself. Fresh chord sounds and a hint of oldskool let this tune become a hotty, that doesnt have to promise anything more. What do seals and electronic music have in common? Well, they almost sound the same! The underwater recordings remind on effect sounds of a modular synth. Therefore its no surprise "Not the End Of The World" easily reconciles seal calls, cracking ice and arctic water. The result is a dubby deep house track that holds all required skills: chords, delay effects, in-depth melodies and loads of an arctic atmosphere. Get your copy! Stream on Spotify! WHATEVER HAPPENED Catalogue No.: ST01 Limited vinyl release. Stefan Tretau returns with this mighty fine techno 3 tracker on the new ST imprint. Two melodic Detroit inspired bangers (title track Whatever Happened and Lily), while EqF kid is on the more minimal modern darker house side. Heavy modern club tools by Tretau! SOLD OUT!

Oscillator radio / analog fm radio with autoamtic cv channel search / 4 HP ⇣ RADIO is an analog FM RADIO with an automatic channel-search functionality. It supports a frequency band of 83,5 - 114 MHz, has a built-in frequency control with signal quality evaluation and runs with automatic noise suppression. It is a never ending sound source and a great companion for your Eurorack sampler or audio mangler. 1/3 key features Analog FM Radio Automatic Channel Search with Signal Quality Evaluation Automatic Noise Suppression 83,5 - 114 MHz Bandwidth CV Control over Channel Search or Reset Volume Control Gain Stage at the Output Illuminated ST Modular Logo specs & downloads width: 4 HP depth: 28 mm power: 18 mA @ +12V / 10 mA @ -12V documentation videos description / manual By pressing the buttons CH- and CH+ you can activate the automatic channel-search function up or down the frequency range. If a signal passes the internal quality evaluation the search is ended and the radio signal is available at the OUT socket. If you want to change to another radio station channel-search is also accessible via CV. Simply patch any gate or trigger signal into the inputs CH- and CH +. Two LEDs indicate of a trigger or gate signal is applied. Channel changes can be really quick, if there are good signals close to each other on the frequency band. If the signal is bad the search automatism may need more time to find good signals leading to slower channel changes. The RST button resets the search to the lowest frequency. After reset you will receive some really nice radio noises until you proceed to the next proper channel again. You can also route the CH- CV input to RST via jumper on the back of the PCB. The module has two volume buttons for quick level adjustments. Additionally it has an active GAIN stage adjustable via trimmer in order to raise the maximum volume to modular levels. The patch-cable connected to the OUT socket acts as an antenna. It´s best to choose a long cable and move it around until you receive the best signals. prev Up next

Oscillator chiasso v2 / analog fm drum synth / 14 HP ⇣ CHIASSO V2 stands as an exceptional oscillator, perfect for generating dynamic Techno sounds that consistently captivate through each knob adjustment. In its V2 iteration, it retains the same exceptional sound foundation found in V1. However, V2 introduces innovative enhancements like CV decay inputs and an added noise source for oscillator A, promising even more sonic possibilities. 1/3 key features Two Analog VCOs Two LFOs SQUARE and TRIANGLE Waveforms for OSC and LFO Cross Modulation CV Decay Fade Potentiometer to adjust the Oscillator Mix Trigger and Pitch Normalization Wrong Polarity Protection specs & downloads width: 14 HP depth: 28 mm power: 55 mA @ +12V / 35 mA @ -12V documentation videos description / manual The module has two oscillators that can generate square or triangular waveforms that you can seamlessly crossfade with the WAVE potentiometers. Each oscillator has its own CV decay envelope, a pitch potentiometer and can be triggered with a trigger signal patched to the left TRIG input as well as individually via the left and right TRIG inputs. A fade potentiometer offers the possibility to manually fade between both oscillators to adjust the mix. Noise can be added to the left oscillator A to make it a little dirtier. There are PITCH CV inputs with attenuators for each voice which, although they don´t track exactly 1 V/OCT, are very useful for changing the mood of each signal to create very organic and moving sounds. The audio output of each side is normalised to the PITCH CV input of the opposite side. The left side is connected after the VCA and the right side before the VCA to achieve different types of cross-modulations and to apply modulation according to incoming trigger signals. In addition, the module has two individual LFOs with square or triangular waveforms that can be fed to the oscillators for further frequency modulation synthesis. Both LFOs have an attenuator to adjust the strength of the modulation and a RATE potentiometer to change the speed of the LFO cycle. The signals of the two oscillators are mixed and output at the OUT socket. prev Up next

Effects clipping cat / vactrol distortion with diode clipping & lpg / 4 HP ⇣ CLIPPING CAT will make your sounds meow! It's a Vactrol-based distortion that will easily cram a lot of filth and grit into your tone. From sine waves to kick drums, this cat won't miss a scratching post! 1/3 key features Vactrol Distortion Diode Clipping Soft & Hard Clipping „Diode Playground“ for Easy Replacement of Soft Clipping Diodes Vactrol LPG Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 20 mA @ +12V / 20 mA @ -12V documentation videos description / manual Based on the passive and very simple WORKMATE CLIPPING CAT, this souped-up 3U module now features three main controls. GAIN determines the amount of distortion applied to your signal. LEVEL decreases the signal level that is fed into the circuit and the CAT/NO CAT switch activates or deactivates the additional diode clipping function. You can choose whether you want hard (CAT) or soft clipping (NO CAT). Depending on the diodes you solder in, the clipping behaviour and sound will change drastically. CLIPPING CAT will only blink and meow if you set the switch to "CAT" and have set a good amount of gain. The amount of gain can also be voltage controlled using the CV GAIN input socket. Each incoming CV signal can be attenuated with the corresponding potentiometer. The overall gain range can be adjusted using a trimmer on the back of the board. This CV functionality also allows CLIPPING CAT to be used as a low-pass gate with the smooth vactrol-based behaviour we all love. Another trimmer allows the circuit to be optimised for LPG or distortion purposes. To simplify the exchange of diodes for soft clipping mode, there is a "diode playground" on the back of the board where you can easily exchange through hole diodes . Feel free to experiment with different types of diodes and discover novel distortion sounds. Purr! prev Up next

Sequencer isi wren / repeatable random gate and cv generator / 4 HP ⇣ ISI WREN is a great sequencer to quickly generate random sequences and lock them on repeat to create catchy and pounding techno synth lines. 1/3 key features Random CV and Gate Looped Sequences Change Sequence Length Adjust Sequence Range Repeat Different Sequences CV Loop ON/OFF CV Length, Range and Repeat Sync to external Clock Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 35 mA @ +12V / 12 mA @ -12V documentation videos description / manual ISI WREN is a digital sequencer that generates random gate and CV signals synchronized to a clock connected to the CLK input. Depending on the CHANCE slider potentiometer, it either generates random gate and CV signals in the center position or locks the sequence in the upper or lower position. The closer the knob is to the center position, the more frequently the signals change. When a gate signal is patched to the RPT input, the sequence is repeated regardless of the slider position. If you repeat a sequence in the upper position of the slider, two different sequences are repeated alternately. In the lower position, only one sequence is repeated. With the MODE potentiometer you can set the length of the repeated sequence, the CV range and the repetition of the sequences. Set the mode toggle switch to STP and adjust the sequence length from 4 to 16 steps. Switch to RNG and adjust the CV range (octave range). In RPT mode, you can adjust how many times an alternating sequence repeats when the CHANCE slider is in the up position. Mode settings can also be voltage controlled. Patch a CV signal to MODE and adjust its level with the attenuator in order to change the length of a sequence, its range and the repeat mode externally. If no cable is patched to MODE the attenuator acts as a response adjustment of the MODE knob (e.g. smaller range of steps with one turn of the MODE knob if the attenuator is turned to the left). Use the GATE output to control an external envelope generator and connect the CV output to the 1V/OCT input of any oscillator. prev Up next

Modulation & Random slopes / sequenced quad slope generator / 12 HP ⇣ SLOPES is a quad slope generator with integrated gate divider. It is a good tool to create organic and moving changes that match the rhythmic pattern of your patches. 1/3 key features Quad Slope Generator 4x AR Envelope Attenuator per CV Output 8 CV Outputs in Total Internal Gate Divider Clock Input Internal Trigger & Modulation 0V to +10V Range specs & downloads width: 12 HP depth: 28 mm power: 75 mA @ +12V / 49 mA @ -12V documentation videos description / manual It can simultaneously generate 8 control voltages, which are mainly changed with the potentiometers RISE and FALL. The further you turn RISE clockwise, the longer it takes for the slope to reach its maximum voltage. The further you move the FALL slider potentiometer up, the longer it takes for the slope to subsequently reach 0V. Each slope can be triggered with a trigger or gate signal and outputs a voltage from 0 to +10V (inverted outs respectively -10V). If you need lower voltages, an attenuator is available for each slope. Outputs 1 / 2 and 3 / 4 provide a mix of slopes 1 & 2 and 3 & 4, but the mix can be changed by inserting an inverted signal of one slope with the "1 INV" or "3 INV" switch and the SHAPE 1 / 2 and SHAPE 3 / 4 potentiometers, which adds an additional triangle LFO to the two signals. The rate of the LFO can be changed with the RATE knob. In addition, there are inverted outputs for slopes 1 and 3. The RATE knob also changes the rate of an internal gate, which is divided by 2, 4, 8 and 16 and fed to the four slope gate inputs (from left to right). This connection is broken when you patch an external gate or trigger signal into the dedicated GATE input. One LED per slope indicates if a GATE signal is present. To synchronize the slopes to external modules, you can insert a clock or trigger signal into the CLK input. This overrides the internal gate generator and feeds the gate divider to trigger the four edges according to its division. The inserted clock or trigger signal is buffered and passed to the THRU output. The RST/DIR input jack can be used to reset the gate divider or change its direction. The functionality of this socket can be selected by soldering a solder bridge on the bottom side of the board. The slopes can be very short and snappy, but may also last up to 10 seconds.

Effects stereo compressor / feedforward stereo compressor / 6 HP ⇣ STEREO COMPRESSOR is a classic analog feedforward compressor, which takes its sidechain split directly from the input signal. It is based on the THAT4305 Analog Engine® single-chip with integrated Blackmer® VCA. 1/3 key features Analog Compressor Stereo Signal Path THRESHOLD, RATIO and GAIN ON/OFF Switch for Signal Comparison Up to +20dB Make-Up Gain STEREO SUM Compatible Skiff friendly Wrong polarity protection specs & downloads width: 6 HP depth: 28 mm power: 35 mA @ +12V / 26 mA @ -12V documentation videos description / manual STEREO COMPRESSOR has two independent signal paths in order to process stereo signals. The left input is normalized to the right, if you want to compress mono signals instead. The module has three controls and a switch: THRESHOLD determins the level at which the compressor starts working. This can be set from -40dB to 20dB. RATIO sets how much the compressor turns down the volume when the threshold is reached (INF:1 to 1:1). GAIN regulates the amount of make-up gain (-20dB to +20dB) that is applied to the signal. Additionally there is an ON/OFF switch that makes it easy to compare the dry and compressed audio signal. Please note that if you turn THRESHOLD counter-clock wise to the left, you reduce the threshold from 20dB (fully cw) to -40dB (fully ccw). Hence the compressor starts working earlier. If you turn RATIO counter-clock wise to the left you increase the amount of compression from 1:1 (fully cw, no compression) to INF:1 (fully ccw, infinite compression). So turning the knobs down corresponds to compressing the signal. The pictures below show the knobs in a neutral position where no compression is applied. STEREO COMPRESSOR has a similar design as the STEREO SUM CHANNEL modules. If you want to add some compression to your mix STEREO COMPRESSOR is a perfect addition to your STEREO SUM Mixer. prev Up next
