Simply the most versatile and powerful analog modelled polyphonic synthesiser ever produced.

The PolyKB III captures the sound and spirit of the legendary RSF PolyKobol 2 polyphonic synthesizer, including its most revolutionnary feature : Morphing analog Oscillators.

This set it apart from all the other common analog synth recreations, because you have instant access to hundreds of different analog modelled & free running oscillators waveforms. More than in other synthesizer, including those who propose switching between oscillators models. Icing on the cake, they can be dynamically modulated by many sources.

Let’s add : Two gorgeous, creamy multimode filters, self resonating in all modes, and Xils exclusive 0df technology. Three Analog modelled envelopes, with time multiplication, and looping capabilities. Two complex LFOs. They complete the picture to offer you this fat, warm and immediatly inspiring analog sound.

Version 3.0.4 beta (uploaded Oct 16th, 2017):

- LFO S&H issue fixed.

How to fix the "wrong installation of your Xils Lab plugin"

You need to install XILS-lab.polyKB.II.v2.5.4.CE, then XILS-lab polyKB III v3.0.4 CE-V.R will 100% work fine.

This fixes it, because PolyKB III requires PolyKB II to be installed, and PolyKB III is basically an upgrade for PolyKB II.
