The Percussa SSP eurorack module is a module with a shed load of features for your eurorack synth. The basic idea here is that you have a modular within your modular... The different DSP algorithms allow you create different chains of modules to create new effects, synths and more.
The Percussa SSP features a quad core processor running at 1.8 GHz per core 32-bit SIMD and 64-bit floating point arithmetic which allows you to run multiple software modules in parallel on multiple cores.
In this video Bert had a four voice wavetable synth running and he played it via a MIDI keyboard.
