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).
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.
The Chord 1 and Chord 2 channels
Two special Chord channels (programmed in the Global > MIDI > MIDI IN
Control page) can be used to receive notes for chord recognition. These
notes will be combined with the notes received on the special Global channel.
Contrary to the Global channel, the Chord channels are not affected by the
split point. However, the status of the
SPLIT button will change the way
chords are recognized on the Chord channels:
Split status Chord recognition mode
On Decided by the Chord Recognition parameter of the Global > Mode
Preferences > Style page. You can play a single note to play a Major chord.
Off Always Fingered or Expert, depending on the previous situation. You
have to play at least three notes in order for the chord to be detected.
