I'm working on a CZ-101 patch librarian now. Tonight I got the CZ to output it's tone data, and collected it in an array. Now all that's needed is a user interface ("its JUST software…"). I'm working in 'C' because I'm not sure basic can keep up with the MIDI rates (31250 BAUD), though since data can be kept to 257 bytes, this might not be a real problem. If you want to head that way, you need a document from CASIO: "Guidebook for MIDI" that details the codes and formats for the interchange. They'll send it free if you ask. The phone no. is (201) 882-1493. My first attempt will just be to save the data, but ultimately I want to display it all and allow you to diddle it with the mouse. (Should be easier than with the up-down buttons on the synth.). HOWEVER, the codes sent out bear only minor resemblance to the codes displayed in the machine. You'd think that a setup that could go 0-99 would come out in binary 0-99, or with some offset. NO! It comes out in three bytes (a nybble at a time) in a peculiar code. Bottom line is that that part is gonna take awhile. Let me know what you're up to, and I'll do the same.
