Well our commands are plain ASCII, so 7 bit (0-127) is no problem. So 
for SysEx you can use exact the same command strings which you would 
use via serial. Just put the SysEx header before it and the SysEx 
trailer behind it.

There must be an example in the archive, but you can also look to the 
MAX SysEx example.
