I am searching for a schematic for a Casio CT-360. I want to do a bit of a hack to see if I could get some sort of a CV and/or trigger signal out of it for use on a modular synth. Does anyone know of a source for Casio schems? I've tried the usual web searches and seem to recall Casio being a little tight with their tech. Any ideas anyone? Thanks,

Casio, as well as most such companies offer zero technical support. And as bad as they are, try Berhinger. All they'll sell you is maybe knobs. I mean not even wall warts.
It turns out the system was dead. No circuit bending here. The keyboard itself is some sort of diode matrix. I have found a schematic of a simpler Casio system using the same matrix. I may go with the basics with some TTL 7400 circuits for decoding or break out an Arduino and go new school.
I've a Casio WK-1600. I found the owners manual online. It was broke and I managed to get a genuine service manual, for a fee, schematics, part lists, printed circuit layout, but not the source of the micro controller program, from here:
I tracked the failure down to a zener diode, and it is now in working order.
