In MOTU FireWire series, MIDI messages are multiplexed to isochronous packets as well as PCM frames, while the way is different from the one in IEC 61883-6. MIDI messages are put into a certain position in message chunks. One data block can includes one byte of the MIDI messages. When data block includes a MIDI byte, the block has a flag in a certain position of the message chunk. These positions are unique depending on protocols. Once a data block includes a MIDI byte, some following data blocks includes no MIDI bytes. Next MIDI byte appears on a data block corresponding to next cycle of physical MIDI bus. This seems to avoid buffer overflow caused by bandwidth differences between IEEE 1394 bus and physical MIDI bus. This commit adds MIDI functionality to transfer/receive MIDI messages.
