18. Tuning
You can use RPN Fine Tune messages to adjust the master tuning of the SGproX.
First select RPN 01 by transmitting a message of [ Bn, 64, 01, 65, 00 ] (control change #100 with data 01, #101
with data 00) to the SGproX. Then use data entry to specify the value by transmitting a message of [ Bn, 06, mm,
26, vv ] (control change #06 and 38) to the SGproX. In this case, a value of 8192 [ mm, vv=40H, 00H ] will be the
normal tuning value, 0 will be -100 cents, and 16383 [ mm, vv=7FH, 7FH ] will be +100 cents.
19. Changing the pitch bend range
You can use RPN Pitch.Bend Range messages to adjust the pitch bend range of the SGproX.
First select RPN 00 by transmitting a message of [ Bn, 64, 00, 65, 00 ] (control change #100 with data 00, #101
with data 00) to the SGproX. Then use data entry to specify the value. Normally, however, only the upper byte is
used. Transmit a message of [ Bn, 06, mm ] to the SGproX. In this case, a value of 00 will produce a setting of 00,
a value of 1536 (mm=12=0CH) will produce a setting of +12 semitones. The SGproX allows you to specify a
negative setting, but only positive values can be set using RPN messages.
20. If notes are stuck
If for some reason a malfunction occurs on an external device, causing notes to stick or hang, you can reset
the notes either by using the SGproX’s Global mode
〈

page, or by selecting a different mode.
If a note played via MIDI is “stuck,” you can also disconnect the MIDI cable. MIDI transmits a message
called Active Sensing [ FE ] at regular intervals, in order to notify devices which receive this message that
another device is connected. If no MIDI messages are received for longer than a specific interval of time, the
receiving device assumes that the connection has been broken, and will turn off notes and reset controllers
that have been turned on or set via MIDI.
21. Turning off all notes on a channel
When a CC#123:All. Notes Off message [ Bn, 7B, 00 ] (control change #123 with data of 00) is received, all
currently-sounding notes on that channel will be turned off (as though the keyboard had been released).
When a CC#120:All. Sound Off message [ Bn, 78, 00 ] (control change #120 with data of 00) is received, all
currently-sounding notes on that channel will be silenced. While All Note Off allows the decay portion of
the notes to continue, All Sound Off will mute the sound immediately.
However, these messages are intended for use only in an emergency, and are not for use during a performance.
22. Reset all controllers on a channel
When a CC#121:Reset All Controllers message [ Bn, 79, 00 ] (control change #121 with data of 00) is
received, all controller values on that channel will be reset.
