ADDAC System - 712 Vintage Pre
available
ADDAC712 is a dual channel discrete gain staging amplifier, based on a famous discrete preamp board from the 70’s used in some legendary equipment. What caught our attention was the character of it’s clipping and resulting saturation/distortion.The module can be used with modular signals to add a distortion/fuzz character or as a preamp for an external source such as a line source, keyboard, guitar... It’s also a great side companion for our ADDAC711 Balanced Inputs.At the top an On/Off [BYPASS] switch routes the signal into the Effect (Up: Active) or to the bottom output gain stage (Down: Bypassed).The amount of amplification is set by the [GAIN] control, the maximum amount of amplification can be set by the user using the [MAX GAIN] trimmer.Up to ±5,5v the incoming signal will keep it’s integrity, beyond this point saturation will start to increase. At approx. ±6v a hard clipping will start to occur, this clipping also has a particular quality that at extreme levels it drifts the audio 0v bias reference, moving it upwards which results are similar to a Gate effect.In the middle, an x2 op-amp based output gain stage with a clipping LED, which monitors the clipping at the output, and an [OUTPUT] control to set the output volume.Having the top and middle gain stages provides flexibility allowing the user to completely distort the signal on the top stage and tame it’s output level with the second stage.At the bottom, input and output for both channels (left input is normalled into right input).DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder.

ADDAC System - 713 Stereo Discrete Mixer
only 2 left
ADDAC713 is the stereo version of our 703 Discrete Mixer. Inspired by Moog’s CP3 mixer, this is a fully discrete analog mixer and it's not, by any means, your standard breakfast mixer, although it can behave like one.This is a wolf in sheep's clothing. Despite its harmless looks there's a dark snarly soul behind that panel that wants to take your sounds into a realm of gritty gnarly growls.This new version was initially thought of as a percussion mixer, with mono inputs and panning, to allow placing percussive voices in the stereo field, while keeping channel 4 in mono for low end sources like a kick drum or Bass. In the development process we slightly changed this initial idea, adding stereo inputs for the first 3 channels, but still kept the 4th channel in mono.All four [GAIN] controls go to extreme levels, the first 3 channels also feature [PAN] controls.Feedback is used to overdrive the whole mix. As the control is turned clockwise the sound will be clipped harder until it goes completely off, this happens as feedback is increased the audio bias reference also moves up, at extreme levels it offsets the whole signal upwards until it completely goes above the top rail clipping the whole signal hence the resulting gate effect.The [MASTER OUTPUT] sets the overall output gain of the mixer, the two LEDs monitor the audio output signal.The soft clipping switch engages an anti-click circuit which adds a low pass before the output, the switch allows 3 states: Soft low pass / Off / Hard low passFeatures:• Three channels with stereo inputs, gain and pan knob• One channel with mono input and gain knob• Feedback/gate knob• Master output volume knob• Soft clipping switchDIY-Kit-Type:SMD-Kit-1.

ADDAC System - 714 Vintage Clip
available
ADDAC714 is a dual channel soft clipping module.Diode based passive clipping acts as a “brick wall” limiter with a fixed knee given by the inherent diode physics. A passive RC low pass circuit adds a 3,3KHz -3db low pass filter which sculpts the overall tone while also adding further character to the effect.At the top an On/Off [BYPASS] switch routes the signal into the Effect (Up: Active) or to the bottom output gain stage (Down: Bypassed).The amount of clipping is set by the [GAIN] control, it mostly works as a threshold control for how much clipping will be applied. As more clipping is applied the signal’s amplitude will also decrease, to compensate for this we set up a gain compensation stage to keep the output amplitude balanced across the Gain range.Symmetry chooses between bipolar clipping or positive clipping, this relates to the harmonics generated, bipolar for odd and even harmonics (up position) and unipolar for odd harmonics only (down position).At the second stage, an op-amp based x2 output gain with a clipping led, which monitors the clipping at the output, and an [Output] control to set the output volume.Having the top and middle gain stages provides flexibility allowing the user to completely distort the signal on the top stage and tame it’s output level with the second stage.At the bottom, Input jacks for both channels (Left input is normalled into Right input) and output jacksDIY-Kit-Type:SMD-Kit-1.

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 - Chopping Kinky
available
Chopping kinky is a voltage controllable, dual channel wavefolder.As an unique feature it has a chop out that will choose between both channels with a zero cross detector or an external gate.• A wavefolder converts simple signals into richer and more dynamically changing ones. In contrast to a filter, wave folding adds harmonic content to the waveform. It works by amplifying the waveform until it begins to saturate, then rather than clipping, the waveform gets folded back in on itself.• Each of the module’s two channels has a unique wave folding profile. At each input, there are two CV inputs for controlling the level of waveshaping including one that passes through an attenueverter.• Chopping Kinky is DC coupled allowing it to be used for both CV and audio duties; to generate harmonics on an audio signal or kinking LFOs and envelopes.Features:• Two unique wavefolder circuits• Two CV inputs per channel, one with attenuverter.• DC Coupled inputs allowing CV signals.• Chop out with zero cross detector.DIY-Kit-Type:THT-Kit-1.

Erica Synths - EDU DIY Wavefolder

Even though wavefolding is more of a west coast synthesis concept, it’s a great addition to the otherwise very east coast mki x es.edu DIY system. Why? Because it can provide a ton of unusual timbres for your patches: from a slight dash of brightness to harsh metallic drones. That’s why we came up with this super simple BJT-based double wavefolder.We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module.In total, we have developed 9 kits to build a fully-featured modular monosynth: a sequencer, a VCO, a wavefolder, a noise/S&H module, a mixer, a VCF, an Envelope generator, a dual VCA, and an output stereo mixer with a headphone amplifier. Additionally, an affordable eurorack case with a DIY PSU will also be available. While these kits are easy to build, we did not compromise on design and functionality. We will launch one kit every 4-6 weeks. For each kit, there is an extensive user manual (40+ pages; can be downloaded separately) that will dive deep into not only the electronics behind each circuit but also the fundamental principles of sound synthesis. We hope that the mki x es.EDU project will inspire future engineers and will contribute to the ever-growing diversity of electronic music technology.DIY-Kit-Type:THT-Kit-1.

It’ll do wooly warm fuzz, subtle tone shaping with a soft saturation/colour, feedback madness and work as a great output VCA (LPG style tones possibly too). The clipping diodes have been replaced by red LEDs to take account of the change in power supply from 9V in the original Big Muff to +/-12V in Meth Amp.To the fuzz core has been added a bunch of OTAs, each controlling a different aspect of audio processing: gain, regen (a new feature - not present in Big Muff), tone and volume. Thereby, each feature is fully voltage controllable.Additionally, there is a separate x100 preamp which can be used to boost external audio for further processing by Meth Amp.
