10. MIDI applications

Tuning

In Sequencer mode, you can use RPN messages to adjust the tuning of each track. In other modes,
you can use RPN messages on the Global MIDI channel to adjust the master tuning parameter of
Global mode P1. The procedure is as follows.
Select RPN 01.
1
Transmit [Bn, 64, 01, 65, 00] (control change #100 with a value of 01, and #101 with a value of 00).
Use Data Entry messages to adjust the value.
2
Make settings using [Bn, 06, mm, 26, vv] (control change #06 and #38). A value of 8192 [mm, vv =
40H, 00H] is normal pitch. A value of 0 is –100 cents, and a value of 16383 [mm, vv = 7FH, 7FH] is
+100 cents.

Transposing

Only in Sequencer mode, you can use RPN messages to set the transposition for each track. The
procedure is as follows.
Select RPN 02.
1
Transmit [Bn, 64, 02, 65, 00] (control change #100 with a value of 02, and #101 with a value of 00).
Use Data Entry messages to adjust the value. Normally, however, only the upper byte can be set.
2
Make settings using [Bn, 06, mm] (control change #06). A value of 8192 [mm = 64 = 40H] is normal
pitch. A value of 6656 (mm = 52 = 34H) is –12 semitones, and a value of 9728 (mm = 88 = 58H) is
+12 semitones.

Setting the pitch bend range

Only in Sequencer mode, you can use RPN messages to adjust the pitch bend range for each track.
The procedure is as follows.
Select RPN 00.
1
Transmit [Bn, 64, 00, 65, 00] (control change #100 with a value of 00, and #101 with a value of 00).
Use Data Entry messages to adjust the value. Normally, however, only the upper byte can be set.
2
Make settings using [Bn, 06, mm] (control change #06). A value of 00 (mm = 00) sets a pitch bend
range of 0. A value of 1536 (mm = 12 = 0CH) sets a pitch bend range of +12 semitones (1 octave).
The TRINITY series allows negative values to be set as well, but only positive values can be set
using RPN messages.

If a note does not stop

If for some reason a note "sticks" (i.e., continues to sound without stopping), pressing the [RESET]
key or moving to a different mode will normally solve the problem. If the note was played via
MIDI, disconnecting the MIDI cable will stop the note.
MIDI transmits a message known as Active Sensing [FE] at regular intervals. This allows a device
that receives this message to know that an external MIDI device is connected. If no MIDI messages
are received for a certain length of time, the receiving device will decide that the connection has
been broken, and will turn off notes and reset controller values that were received via MIDI.

Turning off all notes of a channel

When a MIDI All Note Off message [Bn, 7B, 00] (control change #123, data of 00) is received, all
notes currently sounding on that channel will be turned off (as though you had released them on
the keyboard).
MIDI All Sound Off message [Bn, 78, 00] (control change #120, data of 00) will stop all sound
being produced on that channel. While an All Note Off message allows note decays to remain, the
All Sound Off message will stop the sound immediately.
These messages are only for use in emergency situations, and are not used while you play, etc.

Resetting all controllers of a channel

When a MIDI Reset All Controller message [Bn, 79, 00] (control change #121, data of 00) is
received, the values will be reset for all controllers currently being used on that channel.
