sheep synth in a cherry ps2 keyboard

I didn't find a proper box, so i'd thought I'd give it a try to put it
inside a cherry keyboard.  But what to do with the keyboard itself?
Should I leave the controller in and try to use ps2 commands, or
should I build a new scanner?

4 pins: CLOCK,DATA,GND,+5V

The clock frequency is 10-16.7 kHz.  11 bit protocol:
start-8data-parity-stop.  Data changes on falling edge and can be
sampled on rising edge.
