About MIDI Decay Time (Control #075) Messages which adjust the AEG decay time set for each Part. The value set here is an offset value which will be added to or subtracted from the voice data. Effect1 Depth (Reverb Send Level) (Control #091) Messages which adjust the send level for the Reverb effect. Effect3 Depth (Chorus Send Level) (Control #093) Messages which adjust the send level for the Chorus effect. Data Increment (Control #096) Decrement (Control #097) for RPN Messages which increase or decrease the MSB value of pitch bend sensitivity, fine tune, or coarse tune in steps of 1. You will need to assign one of those parameters using the RPN in the external device in advance. The data byte is ignored. When the maximum value or minimum value is reached, the value will not be incremented or decremented further. (Incrementing the fine tune will not cause the coarse tune to be incremented.) NRPN (Non-Registered Parameter Number) LSB (Control #098) NRPN (Non-Registered Parameter Number) MSB (Control #099) Messages which adjust a voice's vibrato, filter, EG, drum setup or other parameter settings. First send the NRPN MSB and NRPN LSB to specify the parameter which is to be controlled. Then use Data Entry (page 224) to set the value of the specified parameter. Note that once the NRPN has been set for a channel, subsequent data entry will be recognized as the same NRPN's value change. Therefore, after you use the NRPN, you should set a Null (7FH, 7FH) value to nullify further changes and prevent unexpected results. RPN (Registered Parameter Number) LSB (Control #100) RPN (Registered Parameter Number) MSB (Control #101) Messages which offset, or add or subtract values from a Part's pitch bend sensitivity, tuning, or other parameter settings. First send the RPN MSB and RPN LSB to specify the parameter which is to be controlled. Then use Data Increment/Decrement to set the value of the specified parameter. Note that once the RPN has been set for a channel, subsequent data entry will be recognized as the same RPN's value change. Therefore after you use the RPN, you should set a Null (7FH, 7FH) value to avoid unexpected results. The following RPN numbers can be received. RPN MSB 00 00 00 7F RPN LSB 00 01 02 7F PARAMETER Pitch Bend Sensitivity Fine Tune Coarse Tune Null ■ Channel Mode Messages The following Channel Mode Messages can be received. 2nd BYTE 120 121 123 126 127 3rd BYTE 0 0 0 0 - 16 0 MESSAGE All Sounds Off Reset All Controllers All Notes Off Mono Poly All Sounds Off (Control #120) Clears all sounds currently sounding on the specified channel. However, the status of channel messages such as Note On and Hold On is maintained. Reset All Controllers (Control #121) The values of the following controllers will be reset to the defaults. CONTROLLER Pitch Bend Change Aftertouch Polyphonic Aftertouch Modulation Expression Hold1 Portamento Sostenuto Soft Pedal Portamento Control RPN NRPN VALUE 0 (center) 0 (off) 0 (off) 0 (off) 127 (max) 0 (off) 0 (off) 0 (off) 0 (off) Cancels the Portamento source key number Number not specified; internal data will not change Number not specified; internal data will not change All Notes Off (Control #123) Clears all notes currently on for the specified channel. However, if Hold1 or Sostenuto is on, notes will continue sounding until these are turned off. Mono (Control #126) Performs the same function as when an All Sounds Off message is received, and if the 3rd byte (mono number) is in the range of 0 - 16, it sets the corresponding channel to Mono Mode (Mode 4: m = 1). Poly (Control #127) Performs the same function as when an All Sounds Off message is received, and sets the corresponding channel to Poly Mode. ■ Program Change Messages that determine which voice to select for each Part. With a combination of Bank Select, you can select not only basic voice numbers, but also variation voice bank numbers. For a list of the Voices, see the separate Data List. Appendix Owner's Manual 225
