This parameter specifies relative change with the value of 64 producing 0 adjustment.
As values get higher the sound becomes increasingly eccentric.
Note that for some voices the effective parameter range is narrower than the legal
parameter range.

• RELEASE TIME applies adjustment to the envelope release time set by the voice.

This parameter specifies relative change with the value of 64 producing 0 adjustment.

• ATTACK TIME applies adjustment to the envelope attack time set by the voice.

This parameter specifies relative change with the value of 64 producing 0 adjustment.

• BRIGHTNESS applies adjustment to the cut-off frequency set by the voice.

This parameter specifies relative change with the value of 64 producing 0 adjustment.
Lower voices produce a softer sound.
For some voices the effective parameter range is narrower than the legal parameter
range.

(3-2-1) ALL SOUND OFF (Receive only)

(CONTROL NUMBER = 78H , DATA VALUE = 0)

Switches off all sound from the channel.
Does not reset Note On and Hold On conditions established by Channel Messages.

(3-2-2) RESET ALL CONTROLLERS (Receive only)

(CONTROL NUMBER = 79H , DATA VALUE = 0)

Resets controllers as follows.

PITCH BEND CHANGE

SUSTAIN

0 (off)

SOSTENUTO

0 (off)

SOFT PEDAL

NRPN

Sets number to null. (Internal data remains unchanged)

RPN

PORTAMENT CONTROL

Resets portamento source note number

PORTAMENTO

0 (off)

(3-2-3) ALL NOTES OFF (Receive only)

(CONTROL NUMBER = 7BH , DATA VALUE = 0)

Switches off all of the channel’s “on” notes.
However, any notes being held by SUSTAIN or SOSTENUTO continue to sound until
SUSTAIN/SOSTENUTO goes off.

(3-2-4) OMNI OFF (Receive only)

(CONTROL NUMBER = 7CH , DATA VALUE = 0)

Same processing as for All Notes Off.

(3-2-5) OMNI ON (Receive only)

(CONTROL NUMBER = 7DH , DATA VALUE = 0)

Same processing as for All Notes Off. Omni On is not executed.

(3-2-6) MONO (Receive only) (CONTROL NUMBER = 7EH , DATA VALUE = 0)

Same processing as for All Notes Off.
If the 3rd byte is in a range of 0-16 the corresponding channel will be changed to Mode
4 (m=1).

(3-2-7) POLY (Receive only) (CONTROL NUMBER = 7FH , DATA VALUE = 0)

Same processing as for All Sounds Off and the corresponding channel will be changed
to Mode 3.
