Re: [CZsynth] Re: CZ5000 Sequence Data

My guess is that the data structure is the same, but might just be set up to do 4 tracks. I really should find the CZ-5000 sequencer break down I did. I seem to recall I did sysex dumps and loaded them into a hex monitor/editor.

As I recall, it started out with some data about the 8 tracks (I think control parameters and maybe pointers to where in memory the track data started), followed by the track data for each track. With the hex editor I was able to put in smaller values [shorter note/rest durations] than available from the front panel.

Somewhere I should have a matrix showing what the tokens [hex values] stand for. I seem to recall figuring out the step-entry tokens partially by creating sequences with them (repeat, first ending, etc.), extending the matrix logically, and then testing to see if I was right--typical data mining stuff.

I believe by setting the track polyphony byte to zero, the data would be output via midi only without using internal voices. Since the SZ-1 is just the sequencer, if it has the track polyphony parameter (or whatever it was), my guess is that it wouldn't make a difference on the SZ-1.
