Finally, a little Tech Blurb from the web:

The Kawai K4 is a 61 key (velocity and pressure sensitive) 16 voice multitimbral synthesizer, featuring four oscillators (202 samples), a drum kit, amplitude modulation, dedicated DIADSR volume envelopes for each oscillator, dual low pass digital filters, dual LFOs (saw/triangle/square/random waveforms), auto-bend, 64 presets, 32 multi-effects, and MIDI.
