polyKB is a recreation of a very rare, very powerful polyphonic synthesizer
released in the '80s by a French company.

polyKB is a polyphonic subtractive synthesizer based on two waveform
morphing, alias-free oscillators and a self-oscillating 4-pole low-pass
filter.

The oscillators make a large part of the sound of this synthesizer but the
filter, recreating a standard analog chip of the '80s, with the help of a
very complete modulation section, allow the polyKB to create "incredible
and warm sounds, from gorgeous bass to slow evolving pads, through
aggressive leads and thin crystal keyboards, without forgetting a wide
range of special effects".

The modulation section of 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 chosen (Velocity, sequencer outputs, LFO freq, Filter res, VCO levels,
to name but a few).

polyKB also features a powerful polyphonic sequencer. The sequencer can
record and play 8 voices independently as well as the pitch and the
velocity. To control the sequence, a 2 to 128 steps clock system allows a
wide range of rhythms and patterns. Of course the sequencer outputs can be
assigned as a source of modulation.


The polyKB offers:

* 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 LFOs.
* 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.
