Channel Mode Messages

ALL SOUNDS OFF (Controller 120)

BnH

78H

n = MIDI channel number

00H

0 - FH (1 - 16)

The ALL SOUNDS OFF message is used to immediately turn off all sounds on the specified MIDI channel. Sounds which

are turned off using ALL SOUNDS OFF do not proceed through the normal release stage of their amplitude envelope(s).

RESET ALL CONTROLLERS (Controller 121)

BnH

79H

n = MIDI channel number

00H

0 - FH (1 - 16)

The RESET ALL CONTROLLERS message is used to reset MIDI Controller values for the specified MIDI channel back

to their initial/default states. The RESET ALL CONTROLLERS message will restore the following parameter values in the

CS9236 (Note that restoration of the PITCH BEND CHANGE value in response to RESET ALL CONTROLLERS will not

affect notes already in progress):

Controller/MIDI parameter

PITCH BEND CHANGE

CHANNEL PRESSURE

MODULATION WHEEL

Value after RESET ALL CONTROLLERS

40H, 40H (center)

0H (Off)

ALL NOTES OFF (Controller 123)

BnH

7BH

n = MIDI channel number

00H

0 - FH (1 - 16)

The ALL NOTES OFF message is used to turn off all notes on the specified MIDI channel. Notes which are turned off using

ALL NOTES OFF will proceed through the normal release stage of their amplitude envelope(s). The DAMPER PEDAL

(MIDI Controller 64) ON takes priority over the NOTE OFF and ALL NOTES OFF messages: the NOTE OFF or ALL

NOTES OFF messages are recognized, but not acted on until the DAMPER PEDAL is released (OFF). The SOSTENUTO

PEDAL (MIDI Controller 66) ON takes priority over the NOTE OFF and ALL NOTES OFF messages in a similar way, with

the exception that SOSTENUTO only affects notes which were already active at the time that SOSTENUTO was switched

from OFF to ON (See description of DAMPER PEDAL and SOSTENUTO messages).

OMNI MODE OFF (Controller 124)

BnH

7CH

n = MIDI channel number

00H

0 - FH (1 - 16)

The CS9236 responds to the OMNI MODE OFF message as if it were an ALL NOTES OFF message (See ALL NOTES

OFF). The specified channel remains in OMNI OFF mode (All channels operate only in OMNI OFF mode in the CS9236).
