Editing an existing MIDI Preset
You can program or edit your own MIDI Preset for selecting SongBook Entries.
A special MIDI channel used as the Control channel is needed to send MIDI mes-
sages to select the SongBook Entries, or to receive MIDI messages when selecting
them.

Selecting the SongBook Entries via MIDI
At this point, Pa5X must receive on the special Control channel the NRPN Control
Change messages #99 (MSB, with value 2) and #98 (LSB, with value 64) in fast
succession, as an initialization string. This string must be sent only once, unless
another NRPN control is sent on the same MIDI channel before selecting a differ-
ent SongBook Entry.
After the initialization string has been sent, you must send the selection string,
made of two Control Change messages: CC#06 (Data Entry MSB) for the thou-
sands and hundreds, and CC#38 (Data Entry LSB) for the tens and units. The range
of the Data Entry controls, in this case, is 0~99 (instead of the typical 0~127).
