Hi Royce. Happy New Year.
Firstly i have to say that I do appreciate your work to uncover all the secrets of the bcr 2000.
Of course you’re aware that your excellent TQ 5 editor (and the tx 81z one, included in the bcr files section of this site) is not working with fb 01 (actually the overall output level and the overall portamento rate work)
I also read your previous posts (some years ago) in the forum in a similar thread.
My question is slightly simpler than what the other fb 01 user was asking at that time, but still it’s similar since it’s about sysex parameter data.
Since the fb-01 has such a compressed sysex data format for the voice parameters (i guess you’ve already seen the service manual which includes the sysex tables), and some important values share the same parameter nr.,
I would like to know if you can suggest of a way to use the detune parameter (for example - but also because it’s a very important parameter for fm synthesis) without zeroing or altering the frequency parameter (also a very important one), by just using a couple of buttons (or an encoder) dedicated to each operator’s detune parameter.
For the time being i’m using the frequency parameter and i keep the detune to zero. For the freq. i use “val” folowed by a couple of 00 bytes ( lsb ——> msb, 00 for detune and 00 for keyboard scaling).
