24、y range = 1.127 (Velocity is received only for note-on) When the Multi Part parameter Rcv NOTE MESSAGE = OFF, that part will not receive these messages. For a drum part*, key-off is not received if the DrumSetup parameter Rcv NOTE OFF = OFF. For a drum part, key-on is not received if the DrumSetup p

25、arameter Rcv NOTE ON = OFF. * Drum Part indicates that the Multi Part parameter PART MODE is set to DRUM, DRUMS1, DRUMS2. 1.2 Control changes These messages control volume or pan etc. Their functions are differentiated by the control number (Ctrl#). If the Multi Part parameter Rcv CONTROL CHANGE = O

26、FF, that part will not receive control changes. 1.2.1 Bank Select This message selects the voice bank.

27、 Program Change is received, and then voice bank will change at that time. If you wish to change the voice bank as well as the voice, you must transmit Bank Select and Program Change messages as a set, in the order of Bank Select MSB, LSB, and Program Change. Not received when Receive Bank Select in

28、 Native System Parameters is set to off. 1.2.2 Modulation This message is used primarily to control the depth of vibrato, but the depth of the following 7 types of effect can be controlled. The effect of this message can be changed by the following parameters. Multi Part Parameter 1. MW PITCH CONTRO

29、L 2. MW FILTER CONTROL 3. MW AMPLITUDE CONTROL 4. MW LFO PMOD DEPTH 5. MW LFO FMOD DEPTH 6. MW LFO AMOD DEPTH Effect1 Parameter 7. MW VARIATION CONTROL DEPTH (Valid when Variation Effect is assigned to a part as Insertion) Control#ParameterData Range 1Modulation0.127 If the Multi Part parameter Rcv

30、MODULATION = OFF, that part will not receive Modulation. If the receive channel is a drum part, effects 5 and 6 will not apply. 1.2.3 Portamento Time This message controls the degree of Portamento (refer to 1.2.9). Control#ParameterData Range 5Portamento Time0.127 When Portamento (control number 065

31、) is ON, this regulates the speed of the pitch change. A value of 0 is the shortest portamento time, and 127 is the longest portamento time. If the receive channel is a drum part, Portamento Time is not received. 1.2.4 Data Entry This message sets the value of the parameter which was specified by RP

32、N MSB/LSB (see 1.2.22) and NRPN MSB/LSB (see 1.2.21). Control#ParameterData Range 6Data Entry MSB0.127 38Data Entry LSB0.127 1.2.5 Main Volume This message controls the volume of each part. This is used to adjust the volume balance between parts. Control#ParameterData Range 7Main Volume0.127 When th

33、e Multi Part parameter Rcv VOLUME = OFF, that part will not receive Main Volume. With a value of 0 there will be no sound, and a value of 127 will be the maximum volume. 1.2.6 Panpot This message control the panning (stereo location) of each part. Control#ParameterData Range 10Pan0.64.127 When the M

34、ulti Part parameter Rcv PAN = OFF, that part will not receive Panpot. 0 is left, 64 is center, and 127 is right. 1.2.7 Expression This message controls expression (dynamics within a musical line) for each part. It is used to create volume changes during a song. Control#ParameterData Range 11Expressi

35、on0.127 If the Multi Part parameter Rcv EXPRESSION = OFF, that part will not receive Expression. 1.2.8 Hold1 This message controls sustain pedal on/off. Control#ParameterData Range 64Hold10.63,64.127 (OFF, ON) When this is ON, currently-sounding notes will continue to sound even if note-off messages

36、 are received. If the Multi Part parameter Rcv HOLD1 = OFF, that part will not receive Hold1. 1.2.9 Portamento This message controls portamento on/off. Control#ParameterData Range 65Portamento0.63,64.127 (OFF, ON) When this is ON, the pitch will change smoothly between notes. The time over which the

37、 pitch changes is adjusted by Portamento Time (see 1.2.3). Also, when the Multi Part parameter MONO/POLY MODE = MONO, the tone will also change smoothly (legato) if Portamento = ON. If any of the following Multi Part parameter settings apply, that part will not receive Portamento. Rcv PORTAMENTO = O

38、FF PART MODE=DRUM, DRUMS1, 2 1.2.10 Sostenuto This message controls sostenuto pedal on/off. Control#ParameterData Range 66Sostenuto0.63,64.127 (OFF, ON) If sostenuto is turned on while a note is sounding, that note will be sustained until sostenuto is turned OFF. Sostenuto for the specified part is

39、not received when Rcv SOSTENUTO of the part in Multi Part Parameters is set to off. 1.2.11 Soft Pedal This message controls soft pedal on/off. Control#ParameterData Range 67Soft Pedal0.63,64.127 (OFF, ON) The sound will become mellower when Soft Pedal is ON. If any of the following Multi Part parame

40、ter settings apply, that part will not receive the Soft Pedal. Rcv SOFT PEDAL=OFF PART MODE=DRUM, DRUMS1, 2 1.2.12 Harmonic Content This message adjusts the resonance of the filter that is specified for the sound. Control#ParameterData Range 71Harmonic Content0.64.127 (-64.0.+63) Since this is a rel

41、ative change parameter, it specifies a boost or cut relative to 64. Higher values will produce a more distinctive sound. For some sounds, the effective range may be less than the possible range of settings. 1.2.13 Release Time This message adjusts the EG release time that was specified by the sound

42、data. Control#ParameterData Range 72Release Time0.64.127 (-64.0.+63) Since this is a relative change parameter, it specifies an increase or decrease relative to 64. Increasing this value will lengthen the release that follows a note-off. 1.2.14 Attack Time This message adjusts the EG attack time tha

43、t was specified by the sound data. Control#ParameterData Range 73Attack Time0.64.127 (-64.0.+63) Since this a relative change parameter, it specifies an increase or decrease relative to 64. Increasing this value will make the attack more gradual, and decreasing this value will make the attack sharpe

44、r. 1.2.15 Brightness This message adjusts the cutoff frequency of the low pass filter specified by the sound data. Control#ParameterData Range 74Brightness0.64.127 (-64.0.+63) Since this is a relative change parameter, it specifies an increase or decrease relative to 64. Lower values will produce a

45、more mellow sound. For some sounds, the effective range may be less than the possible range of settings. MIDI DATA FORMAT S03 43 1.2.16 Portamento Control This message specifies the portamento source key number (the key number at which portamento will begin). Data of 0.127 specifies the portamento s

46、ource key. When Portamento Control is received, the currently-sounding pitch will change at a Portamento Time of 0 to the key of the next-received note-on of the same channel. Control#ParameterData Range 84Portamento Control0.127 (C-2.G8) This is received even if Rcv PORTAMENTO = OFF. 1.2.17 Effect1

47、 Depth (Reverb Send Level) This message specifies the send level for the reverb effect. Control#ParameterData Range 91Effect1 Depth0.127 Increasing this value will produce a richer reverb. The effect of the value will depend on the state of the reverb effect. 1.2.18 Effect3 Depth (Chorus Send Level) This message specifies the send level for the chorus effect. Control#ParameterData Range 93Effect3 Depth0.127 Raising this val
