gregsbrain LLC is a modular synthesizer company based in Portland, Oregon. We are currently shipping our first commercial Eurorack module xVox, a four-voice real-time pitch shifter effects module. xVox is 17HP wide with a 1.5-inch diagonal 128x128 pixel RGB OLED display. Color-coded volt-per-octave and trigger inputs controle ach of the four pitch-shifted outputs. Six CV inputs, two of which are knobs, can be assigned to perform various modulation functions. xVox is available as a DIY kit and as a VCV Rack plugin. From time to time there may also be some fully assembled modules available.

These are all the parts in the complete kit. They are all through-hole parts, and while a steady hand and a hot soldering iron are essential no great soldering are required. xVox can easily be assembled in an afternoon. If you get into trouble you can email [email protected] and we will try our best to resolve any problems you are having.

If you want to "try before you buy" or prefer to work in the virtual world this is the link to the VCV Rack plugin library.vcvrack.com/gregsbrain/xVox
Here are download links for a few VCV Rack patches to get started with: rand1.vcv produces quite musical random chord progression with some drop chords thrown in for a little variation. midipoly4.vcv works with an external MIDI keyboard or other MIDI source and lets you play 4 note chords from a single oscillator.
