Yes, I believe it does. I have not come across a file that does this, but this part
02 -> Data (00=OFF, 01=MAP1, 02=MAP2)
selects whether it is normal (instrument), or MAP1/MAP2 (percussion)
So if you had
F0 0A 41 10 42 12 40 10 15 00 0F F7
that should assign a standard instrument channel to channel 10.
We may have to wait for someone with a GS instrument to verify
Actually, I manually edited a test file that Sema provided a while ago for setting custom GS drums. I moved the notes to channel 10 and modified the SYSEX as above.
My editor needs to be updated to reflect this possibility
Both Winamp and MidiPlayer played an organ on channel 10.
