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 messages to select the SongBook Entries, or to receive MIDI messages
when selecting them.
Configure the Control channel
1 Go to the Global > MIDI > General Controls page and choose a MIDI Preset to
be used as a starting point.
2 Go to the Global > MIDI > Midi In Channel page, and assign the Control op-
tion to one of the sixteen available MIDI channels (usually one of the higher-
numbered ones, for example #16).
3 Go to the Global > MIDI > Midi Out Channel page, and assign the Control op-
tion to one of the sixteen available MIDI channels (the same as on the MIDI
IN will work fine).
4 When done, save these settings to a new or existing MIDI Preset, by choosing
the Write Midi Preset command from the page menu .
Selecting SongBook Entries via MIDI
When you are ready to remotely select SongBook Entries, switch to the Style
Play or Song Play mode.
At this point, Pa4X 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 different 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 thousands 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).
The following examples show some typical situations.
▪ Send the following string to select SongBook Entry #77:
Initialization string (CC#99, 98)
Thousands and hundreds (00xx)
Tens and units (xx77)
