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.
- 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).
