The XILS-Lab 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, providing you instant access to hundreds of different analog modeled and 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 0 df technology. Three analog modeled envelopes, with time multiplication, and looping capabilities. Two complex LFOs complete the picture to offer you this fat, warm and immediately inspiring analog sound.

It wouldn’t be a XILS-lab instrument if it didn't have innovative and exclusive features like the Per Voice modulation engines, or the giant Step Modulator. 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.

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.

If you combine these two Per Note modifiers with the True Unison engine, you’ll soon get amazing, dense, and breathtaking 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!

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.
