Sequencer path / dual sequential switch / 10 HP ⇣ PATH proves to be an invaluable asset for distributing signals across various destinations while maintaining rhythmic coherence. It's equally adept at directing multiple CV signals to a single destination, resulting in dynamic and evolving envelopes. Remarkably, PATH also facilitates sequential audio signal routing and switching, adding to its versatile capabilities. 1/3 key features Dual Sequential Switch 2x4 bidirectional Outputs 2x1 bidirectional Inputs Reset Input Sequence Loop to 2, 3 or 4 Steps Mix Output Attenuverter for Each Side LED Indicators Wrong Polarity Protection specs & downloads width: 10 HP depth: 28 mm power: 45 mA @ +12V / 50 mA @ -12V documentation videos description / manual PATH is a dual four position switch that can be controlled with a trigger signal. Any signal that is fed to I/O A or I/O B is being supplied on one of the 4 fours I/O jacks depending on the switch position. This is an easy way to sequentially route one or two sources to four different destinations on each side. As the inputs are bidirectional you may also route 4 or 8 different signals to one or two destinations depending on the switch state if you insert signals into the eight I/O 1-4 jacks and forward the signal using the two I/O A and B jacks. When a trigger is inserted into the Trig Input the first jack I/O 1 is activated and a signal is passed through. With the next trigger jack I/O 2 is activated and so on. After the fourth jack the fist jack will be on again. If you want to shorten the sequence, you may use the switches to loop the sequence to 2, 3 or 4 steps on each side individually. A trigger on the Reset Inputs will reset the sequence to the first step independently for each side. Additionally the Inputs I/O A and B or the currently active I/O 1-4 jacks will be supplied on the Mix Jack depending on the direction you have patched. Each side may be attenuverted using the the potentiometers on top. An LED is indicating the currently mixed signal. prev Up next

Modulation & Random tryfelo / 8hp triple re-settable lfo with clock divider / 8 HP ⇣ Introducing a Triple Re-Settable LFO with Clock Divider – a powerhouse of precision and versatility. With three synchronized LFOs at your command, you're not just shaping sound, you're sculpting time itself. Perfectly in sync, precisely re-settable, and elegantly compact, this module elevates your modular experience to a new level of control and creativity. 1/3 key features Three Square and Triangle Wave LFOs Individual LFO Rates CV Attenuator per LFO Reset all LFOs in connection to single Trigger/Clock Clockdivider per LFO Selectable Clockdivision Rates per LFO Variation creates alternative Rythmical Reset-Patterns Skiff friendly Wrong polarity protection specs & downloads width: 8 HP depth: 30 mm power: 45 mA @ +12V / 32 mA @ -12V documentation videos description / manual Tryfelo has three LFOs that can be reset by a single clock/trigger signal. Each LFO produces either a triangle or a square wave selectable via switch. In the mid position of the switch the LFO is deactivated. You may change the LFO´s rate with the help of a dedicated potentiometer. There are also CV attenuators per LFO available. Three bipolar LEDs are indicating the current state of the voltages. The LFO rate available increases from LFO 1 to LFO 3. LFO 1 will produce fast oscillating waves, whereas LFO 3 will provide very slowly changing control voltages. LFO speeds may be changed individually by choosing different capacitor values during assembly. Each LFO is internally connected to a clock divider that will reset the LFO cycle in connection to an incoming trigger/clock and even holds the LFO value when the clock divider pulse is high. During a hold phase there are still slow voltage movements on low LFO rates to keep a pause interesting. This way you can connect the LFOs to a rhythmical context and create pauses in a very musical way. The clock divider needs a trigger or clock signal at the CLK input, that will be converted into a pulse to create these pauses/holds mentioned above. The length of the pulse depends on the speed of the clock. Slower clocks or clock divisions will create longer pulses. The incoming trigger/clock signal will be divided by 2 or 4 for LFO 1, by 4 or 8 for LFO 2 and by 8 or 16 for LFO 3 selectable via switch. The LFO reset may also be deactivated by setting the dedicated switches to the mid position. Each divided signal may also be taken from the individual clock outputs for further external processing. The RST input will accept any trigger/pulse/clock signal and resets the clock division for all LFOs. VARI accepts any control voltage and produces rhythmical variations of the clock divisions. These variations are not purely random, but will generate alternative trigger patterns in connection to the incoming clock/trigger signal prev Up next

Oscillator trommelmaschine / three-voice hybrid drum synthesizer / 18 HP ⇣ TROMMELMASCHINE is the German name for "drum machine", and it perfectly sums up the essence of such a machine: a versatile three-voice digital and analog drum module that can be used to create a range of kick drums and various percussion sounds. 1/3 key features 3 Voice Drum Generator Digital & Analog Drum Synth plus Noise Two Digital Drum Modes CV Inputs with Attenuators Internal Mixer Individual Outputs Wrong Polarity Protection Firmware based on MI Peaks: Released under cc-by-sa-3.0 License specs & downloads width: 18 HP depth: 28 mm power: 165 mA @ +12V / 72 mA @ -12V documentation videos description / manual This drum module features a DIGITAL DRUM VOICE (D) with PITCH and TONE control that has three modes (with latest firmware V2): KICK, SNARE and PERC. Press and hold the MODE switch for one second to switch between the KICK and PERC modes. When in KICK mode, press the button briefly to switch to SNARE mode. In KICK mode the sliders are MOD1 = DECAY, MOD2 = TRANSIENT, MOD3 = PITCH ENV and in PERC mode MOD1 = COLOR, MOD2 = DECAY and MOD3 = FM AMT. In SNARE mode the sliders are MOD1 = DECAY, MOD2 = SNAPPYNESS, MOD3 = TONE. PITCH and MOD can be changed manually or via CV with dedicated attenuators. If nothing is connected to the CV inputs, the MOD CV attenuators change the response curve of the MOD sliders. Turn them to the right to get a linear response and to the left to get a logarithmic response. This facilitates precise adjustment of the slider positions. The ANALOG DRUM (A) voice has DECAY, DRIVE and PENV (pitch envelope) sliders, plus PITCH and LENGTH (pitch envelope length) potentiometers. These can also be controlled via CV. The PITCH CV input tracks 1V/OCT and can be used to play notes. The EMPH input lets you emphasize the signal. This jack can be used as an input to control the internal VCA, e.g. to feed it with an ADSR. The third voice is a NOISE GENERATOR (N) with COLOR control and DECAY slider. The decay of the noise can also be controlled via CV. All voices have individual trigger inputs (D. TRIG is normalized to the other trigger inputs) and individual outputs and are also summed using an internal mixer at the MAIN output. The volume of each channel can be changed with the volume pots. Loudness LEDs indicate when a voice is close to clipping. TROMMELMASCHINE QUICK START GUIDE: TROMMELMASCHINE_QUICK_START .pdf Download PDF • 984KB prev Up next

Mixer & VCA send / aux send & return / 8 HP ⇣ SEND serves as an excellent performance tool, enabling direct interaction with external effects affecting your sounds. 1/3 key features 2x AUX Send & Return 2x Tone Control Input Level Attenuator LED Indication Wrong polarity protection specs & downloads width: 8 HP depth: 35 mm power: 25 mA @ +12V / 15 mA @ -12V documentation videos description / manual SEND is a send and return unit you may know from ordinary mixers. It has a mono INPUT with a LEVEL attenuator and any signal fed in is sent directly to the stereo outputs OUT L and OUT R. If you turn SEND A to the right, you can adjust the portion of the signal that is sent to the SEND A output.This can then be fed into an external effect and returned in mono or stereo to the upper RETURN (L) and RETURN (R) inputs. The TONE potentiometer accentuates either low (turn to the left) or high frequencies (turn to the right) of the signal routed to the send output. Leave it in the centre position so that the frequencies are not affected. The same applies to SEND B, the lower inputs RETURN (L) and RETURN (R) and the corresponding potentiometers SEND B and TONE. Both send s can be used simultaneously. Two LEDs indicate if a signal is sent to the send output. Gain trimmers are located on the front panel to adjust the gain of the send signal. 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

Modulation & Random good & evil / chained lfo and random voltage generator / 12 HP ⇣ GOOD & EVIL ingeniously captures both order and chaos within a single voltage generator module. Its versatility extends to controlling numerous parameters in other modules, making it an ideal companion for crafting gradual shifts in ambient soundscapes or venturing into dynamic and evolving patch creations. 1/3 key features Four Chained LFOs Controllable Time Attenuator per LFO Output Four Random Voltages Adjustable Amount of Random and Chaos EVIL CV Input Random Gate Wrong Polarity Protection specs & downloads width: 12 HP depth: 28 mm power: 75 mA @ +12V / 55 mA @ -12V documentation videos description / manual The GOOD side consists of a chain of four LFOs. Each LFOs only starts to rise when its predecessor descends. The four knobs control the time it takes for each LFO to rise and simultaneously controls the time it takes for the predecessor to descend. The LFOs have individual outputs with an attenuator. This row of low frequency oscillators can either create very slow envelopes followed by fast changes, just very slow voltage changes or a chain of fast swinging LFOs with their voltage never being the same on the four outputs at a time. The EVIL side generates random voltages that can be influenced by the knobs EVIL 1 and EVIL 2. These change the amount and amplitude of chaos being created. The voltages may move very slow, but also evolve to a burst of changing voltages over the course time. Just like on the good side there are also four outputs on the evil side. Additionally there is a GATE output that provides random gates in conjunction with the EVIL voltages. The EVIL CV input gives voltage control over the amplitude of chaos. An attenuator may lower the amount of voltage being inserted to the EVIL side. The last LFO of the GOOD side is normalised to the CV input of the EVIL side, if no patch cable is inserted into EVIL CV. The voltage range is between +/-3V for GOOD and +/-10V for EVIL. The EVIL outputs usually wobble and meander around +/-2V, but also show peaks of +/-5V, and +/-10V (expecially output V). Using the EVIL CV input forces the circuit to generate peaks more frequently. The gate has a voltage of approx. +6V. prev Up next

Additionally there are two Sub-octaves available that can be added to the output signal by using the Sub potentiometer. Sub-octaves may be activated using the dedicated switches. Of course HONEYEATER also includes classic VCO features like Pulse Width Modulation (manually and via CV), Frequency Modulation (exponential or linear alternatively via switch) and Hard or Soft Sync (changeable via jumper on the back). prev Up next

Effects gritzner / pt2399 delay with two switchable inputs and internal lfo / 8 HP ⇣ GRITZNER Delay is a special kind of module that is able to make all sorts of weird delay sounds, from chorus like effects to total destruction of the original signal. There are no boundaries for your crazyness here. Though the two switchable inputs and the LFO reset always make its output fit into a rythmical pattern of your patch. 1/3 key features PT2399 Delay Two Switchable Inputs, one High-Pass-Filtered Internal LFO for Input Switching Internal LFO for Delay Time Changes LFO with Attenuator and Reset Delay Time CV Input Skiff friendly Wrong polarity protection specs & downloads width: 8 HP depth: 28 mm power: 50 mA @ +12V / 30 mA @ -12V documentation videos description / manual GRITZNER is a short delay with two individual inputs that may be activated alternativley either by hand or with a gate signal. IN A is a standard audio input whereas IN B is a high pass filtered input. Frequencies below 320hz will be filtered out which is quite handy for some delay settings. If the MAN/LFO switch is on the left you can switch between both inputs manually using the A/B MAN switch. If the MAN/LFO switch is in the right position an internal square wave LFO automatically switches between both inputs according to the LFO range set with the help of the LFO potentiometer. Alternatively you may patch an external gate signal (from a sequencer for example) into GATE A/B in order to switch between inputs. The Delay itself is a classic PT2399 delay with its very special touch and a delay time ranging from 30-190mS. It has manual controls for the Delay Rate (going beyond the ICs operation range), Feedback and Wet. The delay rate can be voltage controlled with an external signal or with the help of an internal LFO. You can choose between a triangle and a square wave LFO and you may attenuate its signal with the LFO ATT attenuator. On top the LFO is resettable via the LFO RST input in order to get delay changes in a rythmical manner. The LFO rate can be adjusted with the LFO potentiometer. prev Up next

Mixer & VCA mix & pan / 4-channel mixer with vca, cv pan, and cv scan. / 18 HP ⇣ This module is great for creating ever-changing and organic soundscapes throughout the complete stereo field, making your composition a very varied and a persistently interesting listening experience. 1/4 key features 4-Channel Mixer 4x VCA 4x CV PAN CV SCAN CV SPAN Volume Slide Pots Wrong Polarity Protection specs & downloads width: 18 HP depth: 55 mm power: 92 mA @ +12V / 78 mA @ -12V documentation videos description / manual MIX & PAN completes the ST Modular SUM mixer series with a fully CV-controlled 4-channel mixer. It features CV PAN, VCA per channel and a CV CHANNEL SCANNER. Each channel has a VOLUME SLIDER and a VOL CV input to control the internal VCA. The panning per channelcan be adjusted with the PAN controls or the PAN CV inputs. LEDs indicate the channel volume and the stateof the panning. All channels are sum med and can be tapped at the main output jack. The SCAN and SPAN functions are really the most outstanding features of the module. They provide a unique way to mix 1 to 4 channels using one or two CV signals applied to the SCAN and/or SPAN CV inputs. The scan functionality allows you to output a selection of channels by turning the SCAN knob or applying CV to the SCAN input. The range of channels that are activated is set manually or by CV using the SPAN knob. This not only narrows down the active channels from all to just one, but also reduces the effect the SCAN CV hason the VCAs, as if you were shortening their decay time. When both SCAN and PAN are in the centre position and you turn SCAN, you activate one of the four channels at a time. If you increase SPAN, more of the adjacent channels become audible until all channels have reached maximum volume (from mid to cw position). If you decrease SPAN again, only one scanned channel will be audible (mid position) and it will then start to fade out shorter (turning from mid to ccw position). If a CV signal is present at the SCAN CV input and you turn SCAN to the left, the activated channels are narrowed to the left. Conversely, if you turn the knob to the right, only channels 3 and 4 are activated, and in the rightmost position, only channel 4. All CV inputs also accept audio signals, and it is quite interesting to control them with CVs that transition seamlessly from low frequencies to audio rates.

Mixer & VCA fay v2 / fader, vca, overdrive, decay / 24 HP ⇣ FAY Combines four functional units in a tiny 4HP Module. It consists of a Fader, a VCA, an Overdrive and a Decay/Release Envelope. 1/3 key features Manual Fader/Mixer/Switch Voltage controlled amplifier Decay or Release Envelope Overdrive Functionality Volume Control LED indication Wrong polarity protection specs & downloads width: 4 HP depth: 28 mm power: 25 mA @ +12V / 10 mA @ -12V documentation videos description / manual If you insert two audio sources into the jacks IN A and IN B you may fade between both sources manually using the potentiometer on the bottom. This way you can either mix two waveforms or switch between them.The signal is directly routed to the VCA. Here you can control the volume or amplitude of the audio either manually or via control voltage using the CV jack. If there is a trigger signal at the TRIG input you will be able to control the VCA with the internal decay or release envelope (selectable via jumper). Simply insert a trigger signal into the TRIG jack and use the potentiometer below the LED to control the decay length. The LED indicates the current state of voltage. The envelope time can be set to 10ms or 3s via jumper. Thus is can be very snappy for percussion purposes. The decay or release envelope is also provided at the ENV OUT jack to control external modules via CV. Additionally there is an OVERDRIVE option that may be activated via switch. It is also affected by the CV input and shapes the sound to a certain extend. The OVERDRIVE is fairly subtle and more audible on short decay times. Nevertheless it really crunches up some simple waveforms. In contrast to the first version FAY Mk2 has an improved PCB layout and now only consists of one PCB to solder. prev Up next
