From the owner's manual: cE indicates a checksum error.
Would that be an error on the part of simplesysexxer or the hardware ?
I seem to remember some piece of MIDI equipment reporting a checksum
error when I was sending sysex bulks too quickly. After increasing
the interval between blocks everything was fine. (No idea what
device it was, certainly not a Yamaha mixer though.)
IIRC for my Yamaha DX7 and the C64 software I've written, it was an
issue, when naming a sound with a special Japanese ASCII sign. AFAIR
it was only the combination of one sound + a special name including
this sign, not an issue when using this sign for other sounds. Voodoo
;). The old (first) DX7 itself only provided capital letters, numbers
and the dot, perhaps a few additional signs, my sound bank manager
enabled usage of other ASCII signs.
Hey Ralf, hey Tim,
Thanks for both suggestions. Ralf, you may have the right of it here.
The DMP does have an extended character set that I've used in some patch
titles. Tim, I'll see what I can do to throttle the sysex transmission.
Again, thanks for the suggestions.
Btw, I contacted a retired Yamaha tech who has a service manual for the
unit and is willing to copy it for me. Maybe some help there too.
Hardwarily yours,
dp,
