The Z-DSP is a modular synthesizer component from Tiptop Audio that can process and generate audio using a dedicated digital signal processing processor (a FV1 DSP from Spin Semiconductor)
The Z-DSP can runs programs from catridges that create the delays, filters, oscillators and much more. The possibilities are virtually endless, limited only by the imagination of those who write the applications for it.

I have developped 2 cartriges for the Z-DSP.

Grain de Folie


Grain de Folie is a  Granular Effects

Granular Synthesis uses small slices of sounds (‘grains’) to compose new sounds from existing material. By combining multiple grains of differing lengths, amplitude, pitch and speed creates very characteristic sounds of modern music.

Granular processing requires an amount of memory to hold digital samples for playback. The Z-DSP has one second of memory for the audio used in processing. From this audio buffer the grains will sample smaller sections for playback.

Spring Wave has been announced at winter NAMM 2016 and will soon be available. It is a physical modeling effect.

Physical modeling is the principle of processing a sound through a set of equations and algorithms simulating the behaviour of a real world physical object (string, blown pipe, drum skin, spring, metal bar, piece of wood, etc.). Several techniques have been developed for physical modeling, and two variant of them are available in this cartridge: waveguide (or Karplus- Strong based) modeling, and a spring model that could be considered as a « state space model » as compared to Julius O. Smith III classification.



Here are some videos where both cartridges are used

@tiptopaudio testing the new "Grain de Folie" Granular Card for the Z-DSP, absolutely wild! ✨
