Mixer & VCA mia / 2x2 channel mixer with fader / 5 HP & 28 HP ⇣ MIA is a fairly simple, but very handy 2x2 channel mixer with an optional fader output. 1/6 key features 2x2 Channel Mixer Volume Control for each Channel 2 Channel Fader Fader Volume Wrong polarity protection Skiff friendly specs & downloads width: 5 HP & 28 HP depth: 25 mm power: 35 mA @ +12V / 25 mA @ -12V documentation videos description / manual CH1 & CH2 have two input jacks with VOLUME control potentiometers each. The signals inserted here will be mixed and supplied at the CH1 & CH2 outputs. Simultaneously the signal will be routed to the FADER. The summed signal of channel CH1 & CH2 will be available at the FADE output. Using the Fade potentiometer you may mix the two channels to taste. The overall FADE volume may be adjusted using the FADE VOL potentiometer.If there is a cable plugged into the IN A or IN B jack, the connection of the mixer channels to the FADER is interrupted. Thus you can mix 4 sound sources and fade two additional signals at the same time. Originally this mixer was designed to mix several VCO waveforms with the ability to route each of the mixed signal (from CH1 OUT & CH2 OUT) to external modules, such as effects and filters, and then again mix the externally proccessed signals (using IN A & IN B) to one single output (FADE out) via the fade circuitry. In some cases it might even serve as a stereo mixer. This module is available in 3U and 1U! prev Up next

Utilities & PSU cv pan / stereo panning module / 6 HP ⇣ CV PAN is a traditional CV panning module that is used to distribute a signal manually or automatically to both stereo channels. 1/3 key features Stereo Pan CV Input with Attenuator LED Indication Stereo Input & Output Skiff friendly Wrong polarity protection specs & downloads width: 6 HP depth: 30 mm power: 35 mA @ +12V / 21 mA @ -12V documentation videos description / manual CV PAN is a straightforward CV panning module featuring stereo input and output capabilities. When a stereo signal is connected, you can adjust the PAN knob to distribute the signal evenly to both the L and R outputs when in the center position, or shift emphasis to either the left or right channel by turning the knob accordingly. If a mono signal is used, the left input is automatically routed to the right channel, effectively converting the mono signal into a stereo output. To enable automated pan control, apply CV to the CV input. A complete pan change can be achieved by applying +5V. Adjust the CV input attenuator to the left to reduce the CV level for smaller panning movements. The output sockets deliver the processed stereo signal, ready for routing to other modules.

Oscillator boba fat / dual analog drum generator / 14 HP ⇣ At its core, Boba Fat features two oscillators that empower producers to easily craft both earth-shaking sub-basses and delicate, enveloping kicks. BOBA_BACK_NEW.jpg 1/3 key features Analog Drum Generator Designed for Kick- and Bassdrums Two Voices: Soft Mallet and Hard Mallet Each Mallet may be triggered independently Internal LFO with Sync Volume and Boost per Voice Groove CV Input „Vari“ for Hard Mallet Mod CV Input for Soft Mallet specs & downloads width: 14 HP depth: 28 mm power: 95 mA @ +12V / 65 mA @ -12V documentation videos description / manual BOBA FAT is a dual voice bass- and kick-drum generator. The first voice "soft mallet" generates smooth and warm sounding bass and sub-bass sounds, whereas the second voice "hard mallet" is rather considered to create kick or tom sounds. The eight potentiometers on the left control the soft mallet generator. PITCH controls the frequency, LEVEL the volume and BOOST adds low frequencies turning it clockwise and reduces them turning it counter-clockwise. MOD RATE and MOD ATT control an internal LFO and its attenuation. The LFO will affect the frequency of the soft mallet voice only. Additionally the LFO can by synced to the incoming gate or trigger. TRIG SLEW acts as some kind attack control and reduces transients making it very easy to create very smooth sub-bass drums. DECAY and RELEASE control the duration of the sounds being amplified by an internal VCA. PRESENCE changes the prominence of the sound. You can adjust the response by setting a jumper on the back of the module to either FAST or SLOW, optimizing the soft mallet circuitry for sharper, plucky tones or deeper, sustained bass sounds. The three potentiometers on the very right affect the hard mallet generator. PITCH, LEVEL and BOOST have the same function as for the soft mallet part. PITCH will have a greater effect from 12 to 5 o´clock. Changes from 7 to 12 o´clock are rather subtle, but are set on purpose to add fine nuances with LEVEL and BOOST there. OUT VOL changes the overall loudness of both drums. GATE accepts any gate or trigger signal to activate the generators. A signal at only at GATE will trigger both mallets. If a additional trigger is inserted to GATE S, GATE only triggers soft mallet and GATE S triggers hard mallet separately. This way you can have individual drum tracks for both mallets creating very interesting rhythms. A CV signal at MOD CV will override the internal LFO and CV control soft mallet pitch. It doesn‘t exactly track 1V/oct, but you will be able to play some melodies. A trigger, gate or clock signal at MOD RST lets you reset the internal LFO with an external signal. Any CV signal at VARI will slightly alternate the volume or generate additional triggers for the hard mallet circuit (depending on the incoming voltage). This gives you endless ways of creating fine grooves and interesting rhythms. The circuit was designed to easily go into distortion/clipping to encounter the limits. You may be careful using LEVEL and BOOST controls. Boba Fat definitely needs some fine adjustments in order to find the sweet spots. If you feed the GATE input with a trigger at audio rate you can also use BOBA FAT as a weird sound generator or drone machine. prev Up next

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

In this case you need to make the panel yourself. prev Up next

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

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.

Modulation & Random catch / sample & hold / 6 HP ⇣ Catch is a modular swiss army knife combining a great variety of useful functions in 6 HP modular width. 1/3 key features Stepped Random Generator Sample and Hold CV Clock Generator Attenuverter Offset Noise Source LED indication Skiff friendly Wrong polarity protection specs & downloads width: 6 HP depth: 28 mm power: 38 mA @ +12V / 27 mA @ -12V documentation videos description / manual Catch serves as a modular multitool, integrating a diverse range of valuable functions: Stepped Random Generator Sample and Hold CV Clock Generator Attenuverter Offset Noise Source On top of the module you will find the clock generator with its speed potentiometer. Turning CW will increase the speed of the clocks generated. The speed range can be altered with the ON-OFF-ON switch and CV controlled via the CV jack. The clock signal is forwarded to the CLOCK OUT and to the internal Stepped Random Generator and Sample and Hold circuit. If nothing is patched into the TRIG IN jack, the clock triggers the Stepped Random Generator and provides a random voltage on the C/OUT jack. This connection will be cut in case of an external trigger signal being patched to TRIG. In case of a voltage being patched to IN, this source will be sampled and caught on trig on the C/OUT jack. Either the external or the internal voltage signal can be offset and attenuverted and will be supplied on the A/OUT jack, The left bicolor LED indicates the current voltage being adjusted by the offset and attenuverter and the right bicolor LED shows the random voltage being caught on internal or external trigger. If you patch OUT into your audio path, you will hear very warm white noise. prev Up next

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
