The Synthesizer they should have invented 40 years ago:

  • 3 Morphing oscillators.
  • 2 Creamy Multimode 0df Filters.
  • 3 Envelopes, 2 LFOS.
  • Polysequencer, arpeggiator, vintage effects.
  • Unmatched analog presence and feeling.
  • Tomorrow's technology: Hundreds of modulation, including 2 Unique Per voice modulators, a super-sized step sequencer and two Mod Matrices.

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 revolutionary 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 modeled & 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 modeled envelopes, with time multiplication, and looping capabilities. Two complex LFOs. They complete the picture to offer you this fat, warm and immediately inspiring analog sound.

Per Voice

It wouldn't be a XILS-lab instrument if it didn't have innovative & exclusive features like the Per Voice modulation engines, or the giant Step Modulator, to propel it into the XXIth century.

Make each note different : The Voice XY is a Per Note Quad XY modifier. You can control in a 2D square up to 4 different parameters to create from subtle to wild variations for each coming new note.

Control your sound in 3D Space : With the Space XY module, you can place each note in a 3D True Stereo Space, and build stereo scenes that no additional external effect can achieve. Furthermore, you can make it move with chaotic functions, adding incredible life to your sounds. You have never had so much artistic control over the stereo field.

If you combine these two Per Note modifiers with the True Unison engine, you'll soon get amazing, dense, and breath taking sounds, that will proudly take their place in a mix at once. And to operate it, you simply place and move balls, representing the voices, in a square. So easy, so immediate, so tempting, and ... so powerful.

Hyper Modulations : The Polysequencer can now be used as a 128 steps, 4 lines/16 destinations giant Step Sequencer Modulator, allowing you to sculpt not only the most detailed TranceGate patterns, but also Slides or incredible rhythmic patterns. Or everything together. Or something else, completely new.

More : Dynamic control of envelope segments & levels, LFOs & single oscillators levels. Polyphonic Arpeggiator & Sequencer. Dozens of hard-wired and user customisable Macros modulations. 5 monophonic & polyphonic Play Modes. Syncable LFOs with cumulative waveforms, and reset switch. Polyphonic aftertouch. MIDI Cc assignations to ALL parameters. Preset manager with customisable tags and multi-criteria search engine. Vintage analog modeled Chorus, Delay, Phaser and EQ.Hundreds of presets made by the world's best Sound Designers. And hundreds of presets available with add-on packs. Etc.

Everything is there to allow you to create fully organic and expressive presets: The final encounter between analog authenticity, and the modern age.

NOTE: PolyKB is copy-protected by either of the two available standards: USB-eLicenser or iLok (1&2 and software). You choose the protection you want when you purchase the plug-in.
