MIDI Data Format The following RPN messages can be received. RPN MSB LSB 00 00 Data Entry *1 MSB LSB mm -- *2 00 01 mm ll Parameter name and value range Pitch bend sensitivity mm: 00-24 (0...+24 semitones) Specify up to 2 octaves in semitone steps Fine tuning mm ll:0000-100 cents : : mm ll:64000 cents : : mm ll:127127+100 cents 00 02 127 127 mm --- -- [Note]mm ll: 00 127 (=-87.5) cents is followed by 01 00 (=-87.4) cents. Coarse tuning mm: 40 - 64 - 88 (-24...0...+24 semitones) RPN Null This sets RPN and NRPN numbers to an unset state. Internal data is not affected. *1 Refer to 1.2.4 *2 '--' indicates that the setting value is ignored. 1.2.23 Assignable controller By assigning a control change number of 0...95 to a part, the specified effect can be controlled. This device allows two control change numbers (AC1 and AC2) to be specified for each part. The following parameters specify the effect of AC1 and AC2. • Multi Part Parameter 1. AC1, AC2 PITCH CONTROL 2. AC1, AC2 FILTER CONTROL 3. AC1, AC2 AMPLITUDE CONTROL 4. AC1, AC2 LFO PMOD DEPTH 5. AC1, AC2 LFO FMOD DEPTH 6. AC1, AC2 LFO AMOD DEPTH • Effect1 Parameter 7. AC1, AC2 VARIATION CONTROL DEPTH (Valid if Variation Effect is assigned to a part as Insertion) The AC1 control change number is specified by the Multi Part parameter AC1 CONTROLLER NUMBER, and the AC2 control change number is specified by the Multi Part parameter AC2 CONTROLLER NUMBER. 1.3 Channel mode messages These messages specify the basic operation of a part. 1.3.1 All Sound Off This message silences all currently-sounding notes on the corresponding channel. However, the settings of channel messages such as Hold 1 and Sostenuto will be maintained. Control# Parameter 120 All Sound Off Data Range 0 1.3.2 Reset All Controllers This message resets the following controllers to their default values. Controller Pitch bend change Channel pressure Polyphonic key pressure Modulation Expression Hold Portamento Sostenuto Soft pedal Portamento control RPN NRPN Value ±0 (center) 0 (off) 0 (off) 0 (off) 127 (maximum) 0 (off) 0 (off) 0 (off) 0 (off) Reset the portamento source note number that was received Number unset, internal data is not affected. Number unset, internal data is not affected. The following data is not changed Parameter values specified by program change, bank select MSB/LSB, volume, pan, effect send levels 1, 3, 4, RPN and NRPN. Control# Parameter Data Range 121 Reset All Controllers 0 1.3.3 All Note Off This message turns off all notes which are currently on for the corresponding part. However, if Hold 1 or Sostenuto are on, notes will continue to sound until these are turned off. Control# Parameter 123 All Note Off Data Range 0 1.3.4 Omni Off Perform the same processing as when All Note Off is received. Control# Parameter 124 Omni Off Data Range 0 1.3.5 Omni On Perform the same processing as when All Note Off is received. Control# Parameter 125 Omni On Data Range 0 1.3.6 Mono Perform the same processing as when All Sound Off is received, and if the value (mono number) is in the range of 0...16, set the corresponding channel to Mode4* (m = 1). Control# Parameter 126 Mono Data Range 0...16 * Mode4 is a state in which only channel messages on the specified channel will be received, and notes will be sounded individually (monophonically). 1.3.7 Poly Perform the same processing as when All Sound Off is received, and set the corresponding channel to Mode3*. Control# Parameter 127 Poly Data Range 0 * Mode3 is when channel messages will be received only on the specified channel, and will be sounded polyphonically. 1.4 Program change This message reports sound selection changes and changes the program number of the receiving channel. In order to include changes to the voice bank, Program Change and Bank Select messages must be sent as a set (see 1.2.1). When RevPROGRAM CHANGE=OFF for Multi Part Parameter, the program change for that part is not received. 1.5 Pitch bend This message conveys movements of the pitch bender. This message is generally used to modify the pitch of a part, but the depth of the following seven effects can be controlled. The effect of this message can be modified by the following parameters. • Multi Part Parameter 1. BEND PITCH CONTROL 2. BEND FILTER CONTROL 3. BEND AMPLITUDE CONTROL 4. BEND LFO PMOD DEPTH 5. BEND LFO FMOD DEPTH 6. BEND LFO AMOD DEPTH • Effect1 Parameter 7. BEND VARIATION CONTROL DEPTH (Valid when Variation Effect is assigned to a part as Insertion) By default, the Pitch Control effect is applied. If the Multi Part parameter Rcv PITCH BEND CHANGE = OFF, that part will not receive pitch bend messages. 1.6 Channel aftertouch This message conveys the pressure which is applied to the keyboard after playing a note in order to create tonal changes (for an entire MIDI channel). The pressure can be controlled for each part. This message will affect the currently-sounding notes. The effect of this message will be determined by the settings of the following parameters. • Multi Part Parameter 1. CAT PITCH CONTROL 2. CAT FILTER CONTROL 3. CAT AMPLITUDE CONTROL 4. CAT LFO PMOD DEPTH 5. CAT LFO FMOD DEPTH 6. CAT LFO AMOD DEPTH • Effect1 Parameter 7. CAT VARIATION CONTROL DEPTH (Valid when the Variation Effect is assigned to a part as Insertion) By default, there will be no effect. If the Multi Part parameter Rcv CHANNEL AFTER TOUCH = OFF, that part will not receive Channel Aftertouch. CLP-970A 25
