Mute Lock; Multi Mode Equalizer Lock - Yamaha MU128 Owner's Manual

System Functions (SYSTEM)

Mute Lock

Settings: off, on
This determines whether or not the Part Mute
status of the MU128 is reset when receiving
a GM System On or XG System On mes-
sage. Generally, this message is automatically
transmitted to the MU128 as part of GM or
XG song data. When Mute Lock is set to off,
this resets the Mute status of the Parts on the
MU128. If you want to keep the current Mute
settings and disable this reset, set Mute Lock
to on. This setting affects the Multi mode
only, and not the Performance mode. (For
more information on the Mute function, see
page 95.)
Hint
You should set this to "on" when repeatedly
playing back song data for which you want
to keep certain Parts muted. This prevents
the mute settings from being reset each time
you play the song.
A/D Part Lock
Settings: off, on
This determines whether or not the cur-
rent parameter values and Insertion/Varia-
tion effect settings of the A/D Parts are
reset when receiving a GM System On
or XG System On message. If you want
to keep the current parameter values and
Insertion/Variation settings of the A/D
Parts, set A/D Part Lock to on. This pa-
rameter has no effect in the Performance
mode.

Hint
• Set this to "off" when playing back XG-
compatible song data.
• When this is set to "on," all A/D Part set-
tings are maintained, even when "XG Sys-
tem On" or "GM System On" messages are
received. This is convenient when playing
back song data and using a microphone
with the A/D Inputs.

Multi Mode Equalizer Lock

(Mlt EQ Lock)
Settings:
This determines whether the Equalizer set-
tings (page 155) are initialized or change in
response to incoming MIDI messages.
When this is set to "on," the current Equal-
izer settings are maintained, ignoring any
EQ-related messages that are received with
XG System On or GM System On mes-
sages, allowing you to protect your origi-
nal Equalizer settings. When set to "off,"
the Equalizer changes according to incom-
ing XG/GM System On messages. This
setting affects the Multi mode only, and not
the Performance mode.
NOTE
This parameter has no effect on the individual
Part EQ settings (page 116).
