Kurzweil PC88
A performance controller keyboard with 88-note weighted action, built for expressive MIDI control and onboard sound
Overview
The Kurzweil PC88 is a performance controller keyboard made by Kurzweil. It combines a MIDI controller with the feel and built-in sounds of an 88-note digital piano. The weighted-action keyboard responds to velocity and aftertouch. You can layer up to four sounds, and it sends MIDI data on four simultaneous channels, which suits complex live setups. There is no USB. It has standard MIDI ports for hooking up outside gear. An expansion board was developed to add General MIDI compatibility and additional voices.
