Section 3.8. RetMIDIPortRemap / SetMIDIPortRemap (Command ID = 0x27)
Example command block for "channel 7: remap mono aftertouch to channel 3" has the first byte as 0x01 which is actually poly aftertouch according to the preceding format table.
Same error exists for the channel 15 example.
If I'm wrong about this, please advise.
