XILS-lab polyKB

XILS-lab has announced the polyKB, a recreation of a very rare, very powerful polyphonic synthesizer released in the 80’s by a french company.

The polyKB is a polyphonic substractive synthesizer based on two waveform morphing, aliasing free oscillators and a self oscilating 4 poles low pass filter.

One of its features, never heard on other analog synthesizers, was the continuously modulated waveform, sort of a modulated waveform morphing. Recreating this feature in the digital domain, without aliasing was a very big challenge.

polyKB features

  • two aliasing-free morphing oscillators: from triangle to pulse, through saw.
  • one 4 poles low pass self oscillating filter.
  • two envelope generators (ADSR).
  • two MIDI synced LFO.
  • one MIDI synced Sample and Hold.
  • one 128 steps polyphonic sequencer.
  • one arpeggiator.
  • chorus and delay effects.
  • mono/unison/poly playing mode with up to 16 voices of polyphony.
  • all parameters are MIDI controllable.

The polyKB will be available soon as an instrument plug-in for PC and Mac (VST/AU/RTAS).
