Yamaha PLG150-DX MIDI Data Format

MIDI Data Format

1. Channel messages

1.1 Note on/note off

These messages convey keyboard performance data.

Range of note numbers received = C-2...G8

Velocity 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.

1.2 Control changes

These messages convey control operation information for volume or pan etc.

Their functions are differentiated by the control number (Ctrl#).

If the Multi Part parameter Rcv CONTROL CHANGE = OFF, that part will not

receive control changes.

1.2.1 Bank Select

This message selects the voice bank.

Control# Parameter Data Range

0 Bank Select MSB 0...127

32 Bank Select LSB 0...127

The Bank Select data will be processed only after a 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 following order: Bank Select MSB, LSB, and Program

Change.

1.2.2 Modulation

This message is used primarily to control the depth of vibrato, but the depth of

the following 6 types of effect can be controlled. The effect of this message can

be changed by the following parameters.

* Multi Part Parameter

l. MW PITCH CONTROL

2. MW FILTER CONTROL

3. MW AMPLITUDE CONTROL

4. MW LFO PMOD DEPTH

5. MW LFO AMOD DEPTH

By default, an LFO Pitch Modulation (PMOD) effect will apply.

Control# Parameter Data Range

1 Modulation 0...127

If the Multi Part parameter Rcv MODULATION = OFF, that part will not receive

Modulation.

1.2.3 Portamento Time

This message controls the degree of Portamento (see 1.2.9).

Control# Parameter Data Range

5 Portamento Time 0...127

When Portamento 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.

1.2.4 Data Entry

This message sets the value of the parameter which was speciﬁed by RPN (see

1.2.17) and NRPN (see 1.2.16).

Control# Parameter Data Range

6 Data Entry MSB 0...127

38 Data Entry LSB 0...127

1.2.5 Main Volume

This message controls the volume of each part. (It is used to adjust the volume

balance between parts.)

Control# Parameter Data Range

7 Main Volume 0...127

When the 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

produce the maximum volume.

1.2.6 Panpot

This message controls the panning (stereo location) of each part.

Control# Parameter Data Range

10 Pan 0...64...127

When the Multi Part parameter Rcv PAN = OFF, that part will not receive Pan-

pot. 0 is left, 64 is center, and 127 is right.

1.2.7 Expression

This message controls expression for each part. It is used to create volume

changes during a song.

Control# Parameter Data Range

1l Expression 0...127

If the Multi Part parameter Rcv EXPRESSION = OFF, that part will not receive

Expression.

1.2.8 Holdl

This message controls sustain pedal on/off.

Control# Parameter Data Range

64 Hold1 0...63, 64...127

(OFF, ON)

When this is ON, currently-sounding notes will continue to sound even if note-

off messages are received. If the Multi Part parameter Rcv HOLD1 = OFF, that

part will not receive Holdl.

1.2.9 Portamento

This message controls Portamento pedal on/off.

Control# Parameter Data Range

65 Portamento 0...63, 64...127

(OFF, ON)

When ON, Portamento produces a smooth glide connecting two notes of differ-

ent pitch. The time over which the pitch changes is adjusted by Portamento Time

(see 1.2.3). When the Multi Part Parameter MONO/POLY MODE = MONO, the

tone will also change smoothly (legato) if Portamento = ON.

If the Multi Part parameter Rcv PORTAMENTO = OFF, that part will not receive

Portamento.

* Rcv PORTAMENTO = OFF

1.2.10 Sostenuto

This message controls sostenuto pedal on/off.

Control# Parameter Data Range

66 Sostenuto 0...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.

If the Multi Part parameter Rcv SOSTENUTO = OFF, that part will not receive

Sostenuto.

1.2.11 Harmonic Content

This message adjusts the resonance of the ﬁlter that is speciﬁed for the sound.

Control# Parameter Data Range

71 Harmonic Content 0...64...127

(-64...0...+63)

Since this is a relative change parameter, it speciﬁes an increase or decrease rela-

tive to 64. Higher values will produce a more distinctive sound.

For some sounds, the effective range may be less than the possible range of set-

tings.

1.2.12 Release Time

This message adjusts the EG release time that was speciﬁed by the sound data.

Control# Parameter Data Range

72 Release Time 0...64... 127

(-64...0...+63)

Since this is a relative change parameter, it speciﬁes an increase or decrease rela-

tive to 64. Increasing this value will lengthen the release time that follows a note-

off.

1.2.13 Attack Time

This message adjusts the EG attack time that was speciﬁed by the sound data.

Control# Parameter Data Range

73 Attack Time 0...64... 127

(-64...0...+63)

Since this is a relative change parameter, it speciﬁes an increase or decrease rela-

tive to 64. Increasing this value will make the attack more gradual, and decreas-

ing this value will make the attack sharper.

1.2.14 Brightness

This message adjusts the cutoff frequency of the low pass ﬁlter speciﬁed by the

sound data.

Control# Parameter Data Range

74 Brightness 0...64...127

(-64...0...+63)

Since this is a relative change parameter, it speciﬁes an increase or decrease rela-

tive to 64. Lower values will produce a more mellow sound.

For some sounds, the effective range may be less than the possible range of set-

tings.

1.2.15 Data Increment/Decrement (for RPN)

This message is used to increment or decrement values for parameters speciﬁed

by RPN (see 1.2.17), in steps of 1.

Control# Parameter Data Range

96 RPN Increment —

97 RPN Decrement —

The data byte is ignored.
