I am trying to use single note change and bulk upload and I cannot get 
them to work. I thought the upload might be my checksum calculation, so 
I tried getting a download to see if I could replicate the number 
generated by the Proteus module, but I can't. Worse, the MIDI spec and 
the Proteus manual includes different parts of the message in the 
checksum calculation. I can't get the single note ones to work either 
and these don't have a checksum in them so it may be wrong about what I 
am expecting to happen.

If anyone has any code (or even a binary SSNC or Bulk dump) that works 
I would be grateful.
Thanks,
Keith
