Unique and innovative Eurorack Modules
gregsbrain LLC is a boutique modular synthesizer company based in Portland, Oregon. Our focus is innovative digital Eurorack modules operating on waveform analysis and synthesis in the frequency domain.
Our first product, xVox which gives you four voice polyphony out of the oscillators already in your rack has a major update. xVox firmware version 2.0 has a completely new envelope generator, a new set of filter options including a comb filter and now supports USB MIDI.
We are offering xVox as a DIY kit and occasionally a few hand-assembled modules.
There is also new firmware for dSpec our direct spectral synthesis dual VCO. Version 1.4 has much faster pitch tracking and the improved audio frequency modulation.
dSpec is available fully assembled but we also have parts for kits. Let us know if you are interested.
Our modules are also available free VCV Rack plug-ins.
