I checked out the Novation KS4 synthesizer while it was making its debut here at Sweetwater yesterday and it is one amazing synthesizer. This synth is an extension of the engine that the A station and K Station are based upon. It includes incredible liquid sounding filters, an arpeggiator, vocoder and Novation's "Hyper Sync" technology. We should have some to ship to our customers in a few weeks. Definately something you all should check out!
