MIDI data structure:
MIDI data is always sent as 34 nibbles to form 17 full bytes.
Within this data are special characters that are used as
placeholders:
$F1 Value
Any occurance of this byte will be replaced with a number
between Min and Max values, depending on the state of the
control.
$F2 Global Midi Channel
Append the global midi channel # to next byte.
$F3 Clear Checksum
Start computing the checsum starting with the next byte.
$F4 Roland value
Send value followed by Roland Checksum, then $F7. Use
instead of $F1 for Roland products.
$F5 Ensoniq value
Send Ensoniq Nibbleized Value. Use instead of $F1.
$F6 Korg Value
Use instead of $F1 for most Korg devices.
$F7 Sysex EOX and end of data.
If no value has been sent yet, it will be sent now before the
$F7. If message is longer than 17 bytes, just pad out with 0s
$F8 Lexicon Value.
Send Lexicon Nibbleized value. Use instead of $F1.
$F9 Korg WS Value.
Use instead of $F1 for the Korg WS.
$FA thru $FC are used to send Start, Continue, and Stop.
