Schematic search for Casio keyboard

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,

-Kevin

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.
