The upgraded ProtoPlasm 21 has been reworked at a great extend and has become nearly a completely new synth. With it’s new features like Super Modulation Morphing (SMM), key-control on Delay (LKO), LFO modulation matrix and a dedicated Attack Oscillator it enhances it’s main purpose as synthesizer for vivid textures, soundscapes and pads. Even more with SMM and LKO there is a highly improved realtime control now. 384 patches included. (note: not patchcompatible to prior versions)


  • New: one dedicated Attack Oscillator with 50 waveforms controllable by adjustable velocity amount
  • New: Super Modulation Morphing via Mod Wheel at selectable rows for the Mod Matrix
  • New: Modulation Matrix for LFOs with positive and negative inputs
  • New: LKO system for delay with four keydependant modes
  • three digital PCM-wave oscillators powered by 128 different waveforms (123 new ones!)
  • each oscillator’s level can be modulated by different sources via mod matrix
  • one LP filter (24db Lowpass) with ADSR EG, Filter FM and keytracking
  • one HP filter (12db Hipass) with ADSR EG, Filter FM and keytracking
  • two shapeable LFO with patternlike waveforms (bpm-synced)
  • one LFO with 21 complex waveforms and free speed adjustment
  • one shapeable Sample & Hold with pattern (bpm-synced)
  • adjustable level for direct, LP and HP output with separate pan each
  • stereo-delay (bpm-synced)
  • four Lazy buttons (Oscillator, Filters, LFO and All related params)
