ADDAC System - 107 Acid Source
only 2 left
We started this module with the idea of developing a complex drum source. However, somewhere along the process we noticed how much better it performed as a synth voice and simply embraced this lucky accident.It features a VCO with a [FREQUENCY] and [FINE TUNE] knob plus a dedicated CV Input and Attenuator knob (tunable over 4 octaves). The VCO waveform output is achieved by selecting either a Triangle or Saw through a switch. The selected waveform can then be mixed/balanced against the square wave. The resulting mix is then sent to the Filter.The Filter features a [CUTOFF] and [RESO] resonance knob plus a Cutoff CV Input and Attenuverter knob.A 3 position switch is used to select the filter type: Highpass, Bandpass or Lowpass. The resulting output is then sent to the VCA.The VCA features an Input with [INPUT GAIN] knob which at maximum can amplify the incoming signal by a factor of 2.This is a very important control, it accepts any signal Trigger, Gate or CV. Whatever input is plugged in the signal is then fed through an AD with a very short attack and controllable decay through the [VCA DECAY] knob plus the CV Input and Attenuverter knob. The resulting slewed signal is then used to control the VCA gain. This signal is also sent to the CV OUTPUT as well as the LED monitor.The Accent input adds to the Input signal creating a different amplitude output. The CV OUTPUT is normalled to the Frequency and Cutoff inputs.DIY-Kit-Type:SMD-Kit-2. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module.

AtoVproject - cDVCA (Black)
available
cDVCA or class-D VCA is a new kind of VCA based on an entirely novel concept that is inspired from class-D amplification technology. This is not a transparent VCA and brings a lot of character to the sound.The first VCA that tracks 1V/octConcept: The input signal is turned into an ultrasonic PWM signal (~34kHz). The PWM is scaled to the desired amplitude and then filtered back down to the original signal.The twist: The PWM frequency can be lowered down into the audio spectrum and the frequency can be controlled via its 1V/oct input allowing for crazy waveshaping that tracks your melodies.The drive controls an innovative clipping method that does not rely on overdriving any circuitry and therefore results in distortions with a very defined character.The signal then goes into a 1 pole VCF/tone circuit that allows to keep things under some amount of control as the harmonics produced by this module can be very aggressive.With no input the module generates a simple square wave and therefore can be used a simple synth voice (VCO→VCA-VCF)DIY-Kit-Type:SMD-Kit-1.

Befaco / Divkid - Stereo Strip
sold out at the moment
Stereo Strip takes the idea of a channel strip and makes it modular. We hope that by bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters that you will find new, creative ways to use it in your patches!It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.This module is designed in collaboration with Ben Wilson aka Divkid.Features:• 3 band EQ• Panning (manual and voltage controlled)• VCA level control (manual or voltage controlled)• 3 way performance muting (on-off-momentary)• Soft clipping limiter (distortion!)• Line level input and/or output adjustmentDIY-Kit-Type:SMD-Kit-1.

Dannysound - MM VCA
available
The M.M. VCA is a 6HP Eurorack VCA module based on the classic design by Dr. Robert Moog as used in his first portable synthesiser.The discreet design of the circuit has inherent soft clipping characteristics when driven, which either add harmonics to a pure sine wave orconversely remove higher order harmonics when amplifying waves such as a Saw or Triangle.This has the effect of slightly boosting the fundamental frequency, making sounds that are fatter and warmer than standard VCAs.The M.M. VCA has two inputs with level controls – both inputs are then routed through two VCAs in series (PRE-AMP and MAIN AMP).This allows for modulation of the first VCA (PRE-AMP) with an LFO and the second (MAIN AMP) with an Envelope Generator.An offset control provides a DC control voltage to the first VCA that can be used to bias the modulation so it doesn’t cut offWhen the LFO is in the negative part of its cycle. This control should be set to full if modulation of the first VCA is not being utilised.Features:• 2 x Audio Input Level Controls – Starts soft clipping after approximately 50%.• CV 1 (PRE-AMP) Level – Adjusts the amount of CV to VCA 1.• CV 2 (MAIN AMP) Level – Adjusts the amount of CV to VCA 2 (Normalled to 10V).• CV 1 OFFSET Amount – Adjusts the amount of DC bias control voltage to VCA 1.DIY-Kit-Type:THT-Kit-1.

Herzlich Labs - Omen
available
The Omen is a dual LPG with a bit more than you might be used to. Like you, I once was lost in the world of low pass gates, seeking something more, something bigger and somehow juicier. The inspiration came to me as I was reading a particularly heavy book on passive filters, and I realized it was possible to make far more interesting LPG designs than the standard we've become so accustomed to.In a convergence of old-school LPG design and more modern components, the Omen boasts two -6dB resonant filters, custom built vactrols, built in CV attenuation and no less than three cutoff modes per filter. Filter 1 is soft and light, imparting a gentle, naturally gated touch of filtering on your sound, while Filter 2 is darker and more resonant, and can turn downright growly and distorted when left wide open.Designed to give you as many creative options as possible, the Omen has the unique ability to function as either two discrete LPG, or as one 4-pole resonant LPG. When plugging a signal in to Input 1, and with no signal plugged into Input 2, the output will be present at both Output 1 and Output 2, with Output 2 producing the signal as it passes through both filters. Tweaking both filters independently will generate a wide array of soft and sometimes harsh tones, ranging from Buchla bongos to early synthesis brass and organ sounds. There is much to love here.CV is similarly handled, by plugging in only one CV source, it will act on both channels - this is useful for creating musically similar outputs as well as when using the dual filter operation. However, the dual filter mode greatly benefits from having two CV inputs: use an envelope in CV1 to act as a VCA, and an LFO in CV2 to create tremolo, for instance.Using custom designed, hand built vactrols, care has been taken to mitigate the less desirable aspects of passive LPGs - in most modules, the user can expect zero bleed through on the LPG channels, and signal attenuation is minimal even with the 4-pole filter settings engaged. Of course, many of the natural features of vactrols remain, such as subtle memory effect when engaging the vactrol for long periods.DIY enthusiast? Rejoice! The Omen is available as a fully loaded DIY kit - everything you need to build your very own Omen packed in one place, so you can easily build one in the comfort of your own home. It is not a difficult DIY project, an ambitious beginner or someone with experience from a few easy builds can tackle the Omen in an afternoon. The build is all through-hole aside from three SMD components, which are easily soldered by hand due to their large size.Finally, you receive maximum blinkenlights as LED's on the front panel simulate the action of the vactrols, so you'll always know what's going on under the hood. No collection of fancy LPG's is complete without the Omen - add some analog warmth to your signals, today.Features:• Functions both as two discrete LPGs or as one multi-pole filter LPG• A passive LPG without the characteristic signal bleed or input loss• You read that right: each LPG contains a resonant two-pole filter• Comprehensive build guide, complete with picturesDIY-Kit-Type:THT-Kit-1.

MRG Synthesizer - VCA
sold out at the moment
The MRG VCA is a dual linear VCA module, based on the AS3360 (clone of the CEM3360).It's an extremely flexible module and can be used in a variety of ways.Both VCAs can be controlled by a CV entry, modulated by control knob.VCA1 also has an initial gain control (B1), that offsets the CV input by a constant value.This allows VCA1 to be left always open, with the initial gain controlling the amplification.If both input jacks are used (IN1, IN2), the two VCAs will operate independently.The output of VCA1 will go to OUT1, the output of VCA2 will go to OUT2.If there's no jack in IN2, the two VCAs will be cascaded, and the output of VCA1 will go both to OUT1 and as an input to VCA2.This allows this module to be used to process both the MIDI Velocity and the envelope of an audio signal.DIY-Kit-Type:SMD-Kit-1.
