Special MIDI channels
The Control channel
You can set a MIDI IN channel as the Control channel (in the Global > MIDI
> MIDI IN Channels page), to select Styles, Keyboard Sets and SongBook
Entries from an external device (see the Appendix for a list of messages
corresponding to Pa4X’s internal data). On this special channel you can also
send controls to start/stop the Arranger and Players, and select the Style
Elements (see later in this part).
A MIDI OUT channel set as the Control channel (set in the Global > MIDI >
MIDI OUT Channels page) can be used to send messages when selecting
SongBook Entries.
The Global channel
Any MIDI channel can be set as a Global channel (in the Global > MIDI > MIDI
IN Channels page), and can simulate the Pa4X integrated keyboard. When
Pa4X is connected to a master keyboard, transmission should take place
over the Global channel of Pa4X.
MIDI messages received over a Global channel are affected by the status
of the SPLIT button, as well as by the split point. Therefore, if the SPLIT
button’s indicator is lit up, notes arriving to Pa4X over this channel will be
divided by the split point into the Upper (above the split point) and Lower
(below the split point) parts.
Notes received on a Global channel are used for the chord recognition of
the automatic accompaniment. If the SPLIT indicator is turned on, only the
notes below the split point will be used.
