The SK-1 is a small sampling keyboard made by Casio in 1985.
It's really an amazing machine for circuit bending, it produce an infinity of wonderfull sound and video glitchs that no laptop will ever succed to produce and it gives the feeling of getting into the other side of the mirror of electronic music and... blablabla... Sorry, I mean it really-really-really rocks ;D

Some of the modifications I did :
RCA Patchbay, Midi-Input, Trigger-Input, Video-Output (2 modes), Pitch, 555 LFO Timer, Joystick-Input, Presets for Live Sessions...
& more to come...
