Mixer & VCA spm / 3-channel spread mono mixer / 4 HP ⇣ SPM becomes particularly valuable as it enables the dispersion of two mono signals throughout the stereo field within an audio mix. This capability proves instrumental in tidying up the overall mix, resulting in a more expansive and enjoyable auditory experience for listeners. 1/3 key features Analog Mixer 3 Mono Channels Pan CH 1&2 with one Knob Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 19 mA @ +12V / 11 mA @ -12V documentation videos description / manual SPM is a 3-Channel Mono Mixer with three volume potentiometers. The gain per channel can be adjusted with trimmers on the board, making this mixer suitable for line and Eurorack levels. In addition, you can pan channel 1 and 2 with the SPREAD potentiometer and thus spread both channels in the stereo field to the left and right in opposite directions. In the centre position, all channels are panned to the centre. If you turn the potentiometer to the left, channel 1 is panned to the left and channel 2 to the right and vice versa. This is very useful to quickly clean up a mix and widen the sound spectrum in the stereo field. prev Up next

Utilities & PSU cause & effect / voltage reader, sample & hold and gate switch / 4 HP & 20 HP ⇣ Introducing the Cause & Effect module – the maestro of musical mischief in your Eurorack setup. It's like the conductor of a whimsical symphony, where flipping switches and twiddling knobs creates a chain reaction that turns chaos into pure sonic magic. Who knew that cause and effect could be this much fun? 1/6 key features Three Utility Tools Voltage Reader for Gates Hold for Sampled Voltages Gate Switch Gate Switch Inverter Two Hold Modes Inputs Normalised Accepted input voltages for all inputs: -8V to +8V (CV & Audio). Available in Intellijel and Pulp Logic Tile Format Skiff friendly specs & downloads width: 4 HP & 20 HP depth: 30 mm power: 35 mA @ +12V / 31 mA @ -12V documentation videos description / manual The first unit is a VOLTAGE READER, that outputs a gate signal according to a limit set with the help of the READ LIMIT potentiometer. If the limit set (any voltage between -6V and +6V) is reached by the incoming voltage, the R GATE output will be high. The limit may also be controlled via external control voltage at the LIMIT CV jack. This so-called comparator outputs a gate with an amplitude of +/-5V, which also makes it usable as a square wave generator with pulse with modulation via the READ LIMIT potentiometer. Any voltage applied to READ IN is normalised to HOLD IN and IN A. R GATE is normalised to H GATE and SW GATE. This way only one signal is necessary to control both other units. The second unit is called HOLD. In one mode it can sample and store a voltage from the HOLD IN jack and supply it at the HOLD OUT jack, if gate at H GATE is high. In another mode it can pass through the incoming voltage when gate is high. It then samples and stores the last voltage value applied when gate switches to low. The modes are selectable via the HOLD MODE switch. The third unit is a GATE SWITCH. Apply a gate signal to the SW GATE input to route IN A or IN B to OUT. If the gate signal is high, IN A is switched through, and if the gate signal is low, IN B is switched through. When only IN A is connected and IN B is not, OUT produces an inverted version of IN A when the gate is low, and a non-inverted version when high. When only IN B is connected and IN A patched with a dummy cable (a cable that is not connected to another module), IN B can be switched off by a gate signal. If nothing is patched to IN A, the VOLTAGE READER GATE output is normalized to this input. This module is available in 3U and 1U!

Three 1 to 4 Buffered and Attenuverted Multiples & Voltage Source lange anna & anna´s langer arm / three 1 to 4 buffered and attenuverted multiples & voltage source + sattelites ⇣ LANGE ANNA might just be the lengthiest treat in the DIY Eurorack universe! It sprawls across a substantial 84 HP, essentially taking up the bulk of standard cases. The core idea is to effectively carry CV and audio signals throughout the width of a Eurorack case. The satellite modules, ANNAS LANGER ARM, offered in both 3U and 1U format, play a crucial role in further distributing signals across your case. key features 3x 1 to 4 Buffered Multiple Attenuverter per Channel Constant Voltages Normalized to Inputs LED Indication Optional Satellite Modules with Summed Output in 20HP 1U and 4HP 3U Wrong polarity protection Skiff friendly specs & downloads width: 84 HP / 20 HP / 4 HP depth: 28 mm power: 65 mA @ +12V / 50 mA @ -12V documents description / manual This buffered multiple has three channels that multiply each signal to four outputs. For each channel there is a bipolar attenuator to adjust the signal level and polarity. LEDs above and below each output indicate whether a positive or negative signal is present. When nothing is connected to an input, a constant voltage is normalized to the inputs. There is a switch to select the maximum voltage of +10V or +5V. By utilizing the attenuators, you have the capability to employ these voltages for the manipulation of various other module parameters. ANNA'S LANGER ARM was conceived for journeys to distant destinations. Its purpose is to transport signals to unexplored corners, places within your cabinet untouched by any other CV or audio signal. This module establishes a direct link with the LANGE ANNA and eliminates the need for a separate power connection. It offers an additional multiple output per channel and a cumulative output that combines signals from all three channels. The module can be positioned at a considerable distance from your LANGE ANNA unit, effectively spanning the entire width of your modular setup. LEDs positioned above and below each output serve to indicate the presence of positive or negative signals, simplifying the task of assigning an output to a corresponding LANGE ANNA input. Theoretically, you can add as many satellites to LANGE ANNA as you want, as each module has its own buffers. However, there may be some negative side effects when transmitting the signals over very long distances. videos Up

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. Get your copy! Stream on Spotify! SOMETIMES I FEEL LIKE A SHRIMP Catalogue No.: ST05 How does it feel to be a shrimp? And when do you know that the time has come? 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!

These channels are interconnected through flying bus cables and standard ribbon cables at the rear, allowing expansion from a minimum of two channels to suit your requirements and available HP. STEREO SUM is a true performance mixer aiming to be used in live situations. key features Stereo Mixer Customizable Amount of Stereo & Mono Channels EQ per Channel Two Send/Returns AFL Mode to Audit Sounds Mute Switch per Channel +20dB Gain per Channel Stereo Input to Integrate other Mixers Stereo Line Output Mix to Headphone Knob for Sound Comparison Skiff Friendly Wrong Polarity Protection specs & downloads width: min. 12 HP depth: 30 mm power: min. 47 mA @ +12V / 33 mA @ -12V documents videos layout suggestions description / manual STEREO SUM is a stereo mixer with a customizable amount of stereo or mono channels. Tailor your setup by selecting the desired quantity of SUM CHANNELS or MONO CHANNELS to integrate with the SUM MAIN module. Each STEREO or MONO CHANNEL has a mute switch, a one knob EQ, Pan, a Send knob that can be routed to two different destinations, a Level pot and an AFL (after fade listening) functionality, which allows you to audit your sounds on the headphones before you add them to the mix (pre Pan though). Fully counter-clockwise the channel is only routed to the headphones (AFL), turning it clockwise it will be smoothly subtracted from the headphone out and added to the main mix (Mix). The SUM MAIN module has all output, send and return jacks, a master volume knob and a 6.3mm stereo headphone jack with a dedicated volume potentiomter. The Mix to AFL knob routes the main mix output to the headphone out in order to compare the channels that are in AFL mode with the main mix. This can be deactivated with a switch to only audit channels that are currently not send to the main output (AFL mode). Additionally there is a stereo input to integrade other mixers, like PHOEBE, SUM or uSUM for example. All stereo inputs can also handle mono signals. If you want to save HP it might be a good decision to add some MONO CHANNELs to your STEREO SUM. The send channels can be set to be active either pre or post AFL per channel via a solder bridge. ‚Pre‘ means you can still hear the send/return way when it is in AFL mode (thus the channels signal is actually not audible in the main mix), ‚post‘ means send/return will only work when the channels signal is routed to the main mix. Each channel has two separate GAIN trimmer potentiometers adjustable from the front. For enhanced EQ control of your mix, consider integrating the STEREO EQ . Additionally, you can enhance each channel or the main output with the STEREO COMPRESSOR . TO ENSURE THE MIXER'S FUNCTIONALITY, IT'S CRUCIAL TO HAVE AT LEAST ONE STEREO OR MONO CHANNEL, IN ADDITION TO YOUR MAIN MODULE. Up

Modulation & Random hapha / compact locked random voltage / 3 HP ⇣ HAPHA is a valuable tool for enhancing the organic and enjoyable qualities of your patches. This module generates a synchronized random voltage, tied to an external clock signal, and offers the option to stabilize this voltage into a fixed sequence. It's particularly useful for controlling filters and other sound-shaping parameters in your modular system. 1/3 key features Random Gate and CV Clock Sync Lock CV and Gate to a Sequence External CV Input Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 25 mA @ +12V / 18 mA @ -12V documentation videos description / manual The idea was to generate random sequences by turning a knob. When you turn the LCK knob, a voltage between roughly +9V and -9V is passed to a shift register with an R2R digital-to-analogue converter, which stores the voltages from the pot with each clock signal. Depending on how the control is turned (range and speed), different voltages are sampled, resulting in a different CV and gate sequence. The SER input allows the use of external voltages which are passed to the shift register (mixed with the voltages from the potentiometer). The switch enables or disables the external voltage from the SER input. To use it, simply connect a clock signal to the CLK input. HAPHA will then produce a random GATE signal at the upper output socket and a random CV signal at the lower output socket. You can create and lock a new sequence of voltages and gates by adjusting the LCK knob, and an LED indicator will show when a voltage change occurs. For additional control, if you move the SER switch to the right, you can patch an external voltage (audio or CV) into the serial input SER which will directly influence the random voltages at the outputs. With an external voltage patched, you can still change the sequence by turing the LCK pot. prev Up next

Utilities & PSU usb / usb frontpanel power supply / 3 HP ⇣ USB allows you to power any other USB powered device from your Eurorack PSU. If you are using an ST Modular WORKBENCH or MIXBENCH this is particularly handy. But also other external devices such as external CV Sequencers and Controllers, USB lamps or even mobile phones can be powered from this module. 1/3 key features USB Power 3x USB Type A Sockets On/Off Switch Third Socket Registered for Charging Mobile Devices No +5V Rail Needed Wrong polarity protection specs & downloads width: 3 HP depth: 30 mm power: 8 mA @ +12V / 0 mA @ -12V (LED only, total consumption depending on powered devices) documentation videos description / manual USB has three USB Type A sockets and an on/off switch. You don´t need a +5V power rail on your PSU. „ USB “ internally converts +12V to +5V. The third socket is also registered for charging mobile devices. It supplies +2V on the D− and D+ lines of the USB socket showing the device that it may charge a maximum of 500mA (this is an Apple standard, though charging of other brands worked well, too). As USB directly draws current from your PSU, make sure you have enough „current headroom“ available. Don´t use this module to power devices that draw more than an absolute maximum of 800mA in total, it is recommended to keep it below 500mA. prev Up next

Modulation & Random influencer / multiple random cv generator / 14 HP ⇣ INFLUENCER offers a versatile collection of CV tools and creative unpredictability, divided into five distinctive sections, each serving a distinct purpose. With an array of modulation sources and an added touch of uncertainty, INFLUENCER stands as your comprehensive CV powerhouse. 1/3 key features 5x CV Generators Internal Clock & LFO CV Fall Envelope Sample & Hold/Track A/B Comparator Smooth Random CV Noise Out Input Normalisations specs & downloads width: 14 HP depth: 28 mm power: 110 mA @ +12V / 65 mA @ -12V documentation videos description / manual The TOP SECTION is the VC INTERNAL CLOCK and TRIANGLE LFO. The rate of the clock and LFO can be controlled by the RATE knob or CV. The clock signal is normalised to the trigger input of the FALL section. The TRIANGLE wave at the WAVE socket is also routed to the WAVE/RNDM SWITCH of the FALL section. When the switch is in the upper position and the attenuator is turned to the left, the wave will affect the FALL length. In the lower position, the FALL CV is slowly randomised. The SECOND SECTION is a FALL ENVELOPE GENERATOR. It can be triggered internally or externally and its fall time can be controlled by the FALL TIME knob or by CV. An inverted version of the fall output is also available. The THIRD SECTION is the SAMPLE & HOLD section. In one mode, it can sample and store a voltage from the FALL CV socket and output it at the SP OUT socket when the gate at GATE is high (Sample & Hold). In another mode, it can pass through the incoming voltage when GATE is high. It then samples and stores the last voltage applied when GATE is low (Sample & Track). The modes are selected by the MODE switch. The STEPPED potentiometer controls the level of the incoming CV signal. Internally the CLOCK is normalised to the GATE input. The CV input can be fed by an external signal, an internal SMOOTH RANDOM CV or by internal NOISE. Please note that this section may produce noise bursts in Sample & Track mode. The FOURTH SECTION is an AND / OR COMPARATOR that compares two mixable inputs and outputs the MAXIMUM CV and MINIMUM CV of both. It also generates a GATE at B-GATE if IN B is greater than IN A. Note that MIN LED barley flashes with low CV levels.The LAST SECTION is a DUAL SMOOTH RANDOM CV GENERATOR. It provides a constantly changing CV at SMOOTH I and SMOOTH II, slowly meandering in about 60 second cycles. The SMOOTH CV input will affect the SMOOTH outputs in unpredictable ways, sometimes not at all. Internally there is another SMOOTH RANDOM GENERATOR which is normalised to the RNDM switch position of the FALL section, the CLOCK CV and the SOURCE switch of the SAMPLE & HOLD section. Like the others, this SMOOTH GENERATOR may or may not be influenced by the INFLUENCE input. NOISE OUT allows access to the internal NOISE GENERATOR. You could also use the module as an OSCILLATOR.

Modulation & Random lfot / touch control lfo / 3 HP ⇣ Low Frequency Oscillator featuring an extensive frequency range and a tactile touch control capability. 1/3 key features LFO with 3 Waveforms Sine, Square and Pulse waves LFO FREQUENCY potentiometer LFO RANGE switch Adjustable Pulse width Two touch plates to play the LFO HOLD function PUSH function Wrong polarity protection Skiff friendly specs & downloads width: 3 HP depth: 28 mm power: 49 mA @ +12V / 47 mA @ -12V documentation videos description / manual The LFO provides three voltages in shape of Sine, Square and Pulse waves. It can be used as a control voltage, clock source or patched into the audio path for drum synthesis. The frequency and the frequency range can be controlled by turning the frequency knob and rate switch. Additionally the width of the pulse wave may be manually adjusted. An LED indicates the current speed of the LFO. On the bottom of the panel you will find two touch plates. Using these you can “play” the LFO and become a part of the circuit. By pressing your finger onto the HOLD plate you will be able to stop and reset the LFO cycle. It will start over again when the finger is released. The second touch plate PUSH is altering the frequency of the oscillator. Roll your finger from the top side of the plate to the bottom and the rate will be increasingly speeded up. Or directly press you finger an all plate parts and go crazy! After releasing your finger from the PUSH plate the frequency will smoothly recover to its original speed set by the frequency knob. prev Up next
