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

Modulation & Random wave / cv generator with four connected triangle lfos / 4 HP ⇣ This LFO, harnessing four interconnected LFOs, offers a powerful tool for dynamically altering CV destinations in rhythmic patterns. Its synchronized modulation brings intricate rhythmic control to your creative endeavors. 1/3 key features 4x LFO Out 4x LFO Rate Rate Switch Skiff friendly Wrong polarity protection Illuminated Wave -Logo specs & downloads width: 4 HP depth: 28 mm power: 34 mA @ +12V / 25 mA @ -12V documentation videos description / manual The rate of each LFO may be adjusted with the dedicated potentiometers. Each LFO signal is supplied on the four outputs on the bottom side of the module. Depending on the potentiometer settings also slopes or square- wave s can be generated. Please refer to the demo video below. The fours LFOs are connected to each other creating an LFO-chain. If the first LFO reaches its highest value, the second LFO starts to rise. And when the first output reaches its lowest voltage, the second channel starts to decrease and so on. Each potentiometer controls the time it takes for the LFO to reach its maximum voltage, which also controls the time it takes to reach 0 volts for its inverted counterpart (1&3 and 2&4). Simultaneously the pots control the time the other two LFOs hold their maximum voltage level. Patching all LFOs into a VCO´s sound shaping functions you can create wave -like sounding effects that will repeat periodically. This module is very good for generating very slow cycles when the RATE switch is set to SLOW. Conversely, it can also generate fast cycles when the switch is set to FAST. The state of each LFO is being indicated by the illuminated letters W A V E on top of the module. Each letter will light up when its dedicated LFO outputs a voltage. prev Up next

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.
