ADDAC306 is a 5 channel multi-directional CV generator.You can think of it as a "sweet spot" controller, or a hands-on way of transiting from one state to another.Each of the five channels has MINIMUM, SPAN and DIRECTION controls, a common CV IN and a common TRANSITION CONTROLLER slider.MINIMUM sets the minimum channel voltage.SPAN sets the voltage range of the channel.It essentially sets the maximum voltage that can be output from the channel, relative to what the current channel MINIMUM is. For a given SPAN value, if the MINIMUM voltage is changed then the maximum voltage output from that channel will also change respectively.DIRECTION sets whether the voltage transition for each channel goes from MINIMUM to maximum, or maximum to MINIMUM.The TRANSITION CONTROLLER slider controls the transition from the minimum value (A) to the maximum value (B) or vice versa, according to the settings of each independent channel.Moving this slider generates 5 different voltages with 5 different ranges and directions. The transition can also be operated from a CV source at the CV IN, in which case the slider position acts as an attenuator for the incoming voltage.The maximum range of each channel can be set to either 5 or 10 volts, by 5 jumpers in the back of the module. Only positive voltages are generated at the output.Using the CV IN you can use two ADDAC306 modules to expand your control options to 9 voltage outputs under one common slider control.Use the VC Transitions to multiply the polyphony of a single CV sequencer by passing its outputs through the ADDAC207.VC Transitions makes for an awesome state transition controller. Plug its outputs to various CV controller parameters of your audio effects modules. Set the slider to position A, and set the minimum values for each channel. Then move the slider to position B and set the SPAN settings for each channel. Use the TRANSITION CONTROLLER slider to morph from state A to state B and backwards. Flip the DIRECTION switches to change the direction of the transition for each channel. Use the CV IN to automate the transition using LFOs, ADSRs or sequencers.Plug the output of your ADSR envelope to the CV IN and set the channels differently to get 5 different ADSRs from one common source.This module's development was based on an initial idea by Konstantine Fioretos.DIY-Kit-Type:SMD-Kit-2.

Inspired by our ADDAC701 VCO waveform mixing section, our new VC Signal Router also updates our legacy X-Fade/Panner to a stereo configuration that also allows 4 quadrant mixing.Featuring two dedicated X-faders and a stereo VCA that can also be used as a third X-Fader. All controls have their own CV inputs and dedicated Attenuverters for precision control.4 quadrant mixing is achieved by using the stereo Master as a X-fader between left and right channels, this way you can plug 4 audio sources and sweep/crossfade between each and any of them using the 3 x-faders. Plug any 4 sources (4 waveforms of a VCO, 4 LFOs, 4 envelopes...) and sweep through morph through or have them all mixed together.For other configuration types Left and Right X-fader channels can be routed through the Master stereo VCA or sent directly to the outputs. A stereo Direct input can also be routed through the Master VCA or sent straight to the outputs.The Mono Sum output always mix Left and Right outputs together allowing the possibility to use the module as a peculiar 6 channel mono mixer.It can be used for both Audio or CV Signals.Features:• 6 mono inputs• 2 dedicated X-faders with Control knob + CV Input and Attenuverter Each X-fader can be routed through the Master mix or straight into the outputs.• Master channel can be used as a stereo VCA or an X-fader• Stereo direct inputs can be routed through the Master mix or straight into the outputs.• Fully analog audio path with high quality/low noise VCAs.DIY-Kit-Type:SMD-Kit-2.

Morphader is a performative tool designed to make multichannel CV/Audio crossfade easy and comfortable. Fading from one quad CV/audio scene to another. The core of the module has four CV controlled crossfaders, each with their individual control and a master fader to control them all. The module mixes the four crossfades at its fourth output, thanks to a clever normalization scheme. Each of them can be easily removed from the mix by plugging a cable at its own output.Features:• CV Controlled four channel crossfader.• Attenuators per input.• Normalized voltages to every input, allowing cv levels morphing.• Audio CV response switch per channel• Master Fader control with Lag.• Leds per channel for signal level monitoring.DIY-Kit-Type:SMD-Kit-1.

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.

• Vactrol Mix combines four audio or CV signals into two channels, determined by the random sequence. It’s a great way to create stereo effects, complex waveforms or feedback loops.• This expander is 4 in, 2 out vactrol matrix mixer controlled by the Turing Machine, connected around the back by a 16 pin ribbon cable.• There are four inputs, for audio or CV sources. The four knobs set the level for each input. Next to each knob is a pair of LEDs. When the LED on the left is lit, the signal goes to the left output. When the LED on the right is lit, the signal goes to the right output. The LEDs are controlled by the Turing Machine module. The two outputs are both doubled (mult-ed) to make it easier to patch feedback loops.• Despite being less popular or widespread than Pulses or Volts, this is my favourite Turing Machine expander. It is a unique device that turns mundane source material into wild, unpredictable but rhythmically accessible patterns of sound. It’s a great way to create stereo effects, shifting drones, complex waveforms or feedback loops, and can be the heart of small (but chaotic) system.• Vactrols are electro-optical devices; a light shining on a light-dependent resistor. They have an extraordinary history, from powering the optical soundtracks on the first sound films in the 1920s to studio compressors, the tremolo in Fender guitar amps, and many of Don Buchla's 1970s synth designs. Modern vactrols are an LED pointing at a cadmium light dependent resistor, sealed together in a little black plastic box. Because the LDR reacts relatively slowly, the signals cut together smoothly, with no clicks or pops. Unfortunately, the cadmium in light dependent resistors is banned in Europe, so Vactrols are becoming harder to find.• Feedback is where this module gets really interesting. Try sending the (bottom) left and right outputs to your output mixer, and the (top) left and right outputs to spring reverbs or delays, patching the delay/reverb outputs back into input channels. Carefully ride the input levels, and you'll get snippets of feedback. The main clock speed can have a huge effect on feedback levels, because it takes a while to build up.• There are lots of Vactrol Mix audio examples in my Soundcloud: Twenty Minutes of Madness, Contact Mic Feedback and this ancient track recorded using the breadboard prototype.• The Vactrol Mix is DC coupled, so you can also rhythmically cut up DC sources; mix LFOs at different speeds with audio rate oscilllators, and frequency modulating a pair of oscillators using the two outputs.• This module was inspired by Grant Richter's Cadavre Exquis voltage controlled mixer, which was inspired by André Breton's surrealist game Exquisite Corpse. Richter's mixer also inspired the RxMx module by Make Noise.• Jonathan Higgins, on Facebook: 'There isn't a patch I don't use it on. People often thing you can only use it for crazy stereo percussion (which it is amazing at). But I also often patch all four outputs from the humpback filter into it for evolving stereo drones.'• The Vactrol Mix is a very straightforward through-hole DIY build.
