Whell....how that sounds.... WIERD and GREAT.... It use some kind of 8Bit DSP???? actualy sounds are made from layering waveforms wich are presets in box and can be loaded from punch cards....its sound gridy and warm at same time....realy fast envelopes and nice chorus and vibrato for strings.... can emulate everything....I own PPG 2.3 system and sometimes it sounds fatter than PPG!!!!! cards looks like this it has 8 polyphony and can be in dual mode...4 polyphonic no vcf here but I drive it thru modular vcf with envelope folower and thats a bomb ... as far as I know its realy rare synth maybe 3-4 Europa.....and around 100 made of KC II...maybe less.....
