I've been keeping an eye on this synth for a long time before I finally decided to buy it. Now I only regret I waited this long.

PolyKB II is an emulation of the Kobol synthesizer from the French company RSF. The original hardware synth is very rare. Only around 200 where ever made. But thanks to XILS-Lab this emulation is now available for everyone.

An example of the use of Kobol in synth-pop music of the 80s can be found in Yazoo's song "Only You" where this synth can be heard in the intro of the song.

PolyKB II (player) has a very warm, round and soft sound. It could be compared to the Minimoog, on witch the original hardware synth is inspired by, but with more features.

The player is a cut down version of PolyKB II. But it's still very powerful. Although it don't provide any real in-depth functions it has just enough functions for my needs.

The presets includes leads, basses, pads, sequenzed stuff, FX and much more. And there are more presets available. The PolyKB II player can play all presets of the full version of the synth.

The settings panel is also very good. Here you can, among many other things, find a very nice and easy to use section for assigning your MIDI controller to varous functions.

But the best thing with PolyKB II Player is the sounds! They are very alive. When I play on it I really feel that I'm dealing with a real instrument. I'm really getting personal with this wonderful synth. This is a top favorite in my collection.
