The Z-DSP includes a Halls of Valhalla DSP card.

Tiptop Audio’s Z-DSP is a cartridge-based open source digital sound processing and effects generating platform for your modular synthesizer. Lush audio processing, greater stereo depth and a unique set of digital synthesis is what the Z-DSP is all about.

The Z-DSP has a stereo digital sound processor with 24-bit sampling, 15kHz of bandwidth, voltage-controlled parameters of stereo feedback, program switching, DSP parameters, equal power crossfading dry/wet mixing, as well as sequential program control switching and a clear display – all in Eurorack format. A dedicated clocking input for the DSP chip does wonders to passing sound by bending the algorithms in an unexpected way, a hardware technique computer plugins can’t do and is unique to the Z-DSP.

In a recent update, the Z-DSP (NS) got an all new design of its analog circuitry, contributing to a lower noise signal path, clearer sound of the entire frequency range, lower distortion and better immunity to noise emitted by other modules sharing the same power supply. A new analog dry/wet circuit has been implemented to remove the 3db gain drop when the mix knob passes through the center of the dial making the use of this function more practical in a live application. A reverse polarity protection has been added as well. The new front-panel matches Tiptop’s colorful design, and a single printed circuit board and surface mount technology improve reliability during production and use. The powerful Z-DSP engine remains the same as the original Z-DSP module and all cards are compatible across both versions.
