What can't you do that makes the BCR not suitable?
Negative numbers are the only trick and I think that can be solved from the cursory glance I have had of the sysex spec
Multiple parameters in one byte is also a problem in early synths, but this doesn't seem to be the case here.
Have I missed something??
All the best

Is this correct sysex???
* sysex format:
0xF0 sysex start
0x10 Oberheim ID
dd Device ID: 0x02 for M-12 or Xpander, 0x06 for M-6.
opcode one byte.
(data)
0xF7 sysex end (EOX)
The high bit of each byte is reserved as the status bit, as usual.
Wait at least 20 ms between sysex operations.
* select quick patch edit
0x05 opcode
Send this before changing parameters through remote editing.
"This operation selects the Quick mode of the Patch Edit function.
The M-6 must be in Patch Edit mode in order to act upon parameter
change commands."
* change parameter
0x06 opcode
pp parameter number, 0-99.
vv value. may not be negative. (damn!)
If you want to set negative values, you have to send the whole patch,
breaking the sound. I can't imagine why they didn't just use bit 6
as a sign bit.
* single patch
0x01 opcode
pp patch number, 0-99.
xx yy data, sent nybblewise:
a data byte dd is sent as xx=dd&0x0F; yy=dd>>4
cc checksum:
the sum of the original data bytes dd, masked with 0x7F.
Here I don't see why they chop up the data bytes; none exceeds 7 bits.
