polyKB

The polyKB is 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.

The oscillators take a large part of the sound of this synthesizer but the filter recreating a standard analog chip of the 80's with the help of of very complete modulation section allow the polyKB to create incredible and warm sounds, from georgous bass to slow evoluting pad, through agressive lead and thin cristal keyboards, without fogoten a wide range of special effects.

The modulation section of the polyKB acts like a matrix with five dedicated sources (LFO, ADSR, VCO, NOISE, VELOCITY) and five dedicated destinations (VCO 1 and 2 pitch, VCO 1 and 2 waveform,VCF frequency).

To increase the sound design possibilities, six menus have being added, two for the sources, four for the destination, with which a wide range of modules can be choosen (Velocity, sequencer ouputs, LFO freq, Filter res, VCO levels, to name but a few)


The polyKB brings also a very powerful polyphonic sequencer. The sequencer can record and play 8 voices independently as well as the pitch than the velocity. To control the sequence, a 2 to 128 steps clock system allows a wide range of rythms and patterns.

Of course the sequencer outputs can be assigned as a source of modulation, opening the sound posibilities endless.
