Title: CC to Sysex : checksum calculation
Post by netbert on Nov 13th, 2005, 5:16pm
Hello !
I am trying to control my Roland hardware synth with my BCR-2000  Midi-Controller using midiox data mapping.
Midi data mapping is my only way to do it, since the bcr does not output continuous sysex data.
I can use 3 substitution characters for the channel, controller and value, (FC FA & FB) and output them in my Sysex string, but i need to place the checksum byte before the F7 ending byte...
I think this is a feature request, as i have not found any information about this issue.
If anybody knows an alternative !!!
Thanks a lot !!!

Cheers from France,
Samy
