The Z-DSP is an open-source, cartridge-based, digital sound processing and generating platform for your modular synthesizer. The Z-DSP has a stereo DSP processor with 24-bit sampling. 15Khz of bandwidth, smooth voltage controlled parameters, and has the ability to be programmed - all in a Eurorack format. While the Z-DSP cannot complete with the processing power found on personal computers, it does provide direct control of the DSP hardware and has a unique set of features aimed at the manipulation of digital effects. With the Z-DSP, digital audio can be bent, stretched, deformed, and distorted by interacting with your modules; something personal computers just can't do.

The Z-DSP interface includes VC digital parameters, VC Mix/Dry, manual and sequential program switching, and a pair of VC feedback loop paths with exposed patch points that let you insert the rest of your modular into the DSP process. The Z-DSP lets you go far beyond ordinary processing, breaking the rules and allowing you to patch right into the heart of the DSP chip through the clock input, allowing for some digital madness and creative sound design.
