ALMOST THERE

I fixed the misreported misplayed key problem . I added a WAIT loop on the PIC side to slow the incoming stream to the C64 but now the C64 locks up sometimes????

It was the PIC CHIP Serial data Logic

So I created this little program to emulate me playing all of the piano keys ....and then sending those to the C64 FASTFINGERS software. The program played all of the keys without flaws except some of the very high sounds near the top of the SID chip range.

NECESSITY IS THE MOTHER OF INVENTION

Well, I think that it is safe to say that this is not a software problem. I suspect the Commodore CIA chip so I'm writing a PIC CHIP SEQUENCER to test my theory. If it works well, I may be removing the sequencer from the C64 and use the PIC CHIP to record and play back sequences.

Till next time....

I COULD SCREAM !!!

I HAVE DONE EVERYTHING I CAN TO REMOVE THIS BUG SHORT OF COMPLETELY RE-WRITING THE KEYSCAN ROUTINES AND I AM STILL WITHOUT PROGRESS !!

I opened up all of the analog ports on the pic chip. I moved the C64 interface to a different port. This should make for some interesting pitch tracking applications. Dan
