About MIDI

MIDI channels

Similarly to the way in which a television set operates, the data of a channel can be received when
the receiving device is set to the same channel as the transmitting device. However the way in
which channels are handled differs in each mode.
In Program Play mode, all data is transmitted and received on the Global MIDI channel.
* The Global MIDI channel is the channel used for transmitting and receiving messages that
correspond to a single action on the TRINITY, such as the keyboard, master effects, or exclu-
sive data. On the TRINITY, the Global MIDI channel is set in Global mode P1.
In Combination Play mode, combination selections, master effect control, and exclusive data
are transmitted and received on the Global MIDI channel.
When using incoming data to control timbres (select programs, play, adjust volume, etc.) whose
Timbre Mode is set to INT, the MIDI channel specified for each timbre in (Combination Edit
mode P1) is used.
When you play the TRINITY's keyboard or operate controllers such as the joystick, messages
will be transmitted on the Global MIDI channel, and also simultaneously transmitted on the
MIDI channel of timbres whose Timbre Mode is set to EXT.
In Sequencer mode, master effect control, and exclusive data are transmitted and received on
the Global MIDI channel.
When using MIDI data to control tracks (by selecting programs, playing notes, setting the vol-
ume, etc.) whose Track Status is INT or BOTH, or when transmitting the playback data of
tracks whose Track Status is EXT or BOTH, the MIDI channel specified for each track will be
used (this is specified in Sequencer mode P2).
When you play the keyboard or operate the controllers of the TRINITY, data will be transmitted
on the MIDI channel specified for the track that is currently selected in Sequencer mode.

Note on/off

When you press a note on the keyboard, a MIDI message will be transmitted conveying the key-
board location that you pressed (the note number) and the force with which you pressed the key
(velocity) as a Note On message [9n, kk, vv] ('n' is the channel, 'kk' is the note number, and'vv' is
the velocity).
When you release the note, a MIDI Note Off message (8n, kk, vv) will be transmitted. However
there are very few instruments that transmit or receive Note Off velocity. The TRINITY does not
transmit or receive Note Off velocity.
Each time you play the keyboard, the TRINITY will normally transmit a Note On or Note Off
message on the Global MIDI channel, but this will depend on the mode.
Transmission
• In Program Play mode, data from the keyboard will be transmitted only on the Global MIDI
channel.
• In Combination Play mode, data from the keyboard will be transmitted on the Global MIDI
channel, and also on the channels specified for timbres whose Timbre Mode is EXT.
• In Sequence mode, data from the keyboard will be transmitted on the MIDI channel of the cur-
rently selected track.
When the sequencer is playing, Note On/Off data will be transmitted for tracks whose Track
Status is either EXT or BOTH.
Reception
• In Program Play mode, only the Note On/Off data that matches the Global MIDI channel will
be received.
• In Combination Play mode, only the Note On/Off data that matches the channel setting of a
timbre whose Timbre Mode is INT will be received.
• In Sequncer mode, only the Note On/Off data that matches the channel setting of a track
whose Track Status is INT or BOTH will be received.
