System Functions (Sys) - Yamaha MU100R Owner's Manual

System Functions (SYS)

The System functions provide various controls of the overall operation of
the MU100R, such as Master Tune, Mute and A/D Part Lock, some MIDI
receive filters and a display Contrast control.
Master Tune (M.Tune)
Range: –102.4 — +102.3 cents
(approx. +/– 1 semitone)
This determines the overall fine tuning of
the MU100R's Voices. It also affects the pitch
of the individual drum/percussion sounds of
the drum kits. Master Tune is especially use-
ful for adjusting the pitch of the MU100R
when playing with other instruments. The
actual pitch of each Voice depends also on
the other pitch related parameters: Key (in
Play mode) and Detune (in Edit mode).
NOTE
At around 440 Hz, 1 Hz is approximately
equal to 4 cents.
Mute Lock
Settings: off, on
This determines whether or not the Part Mute
status of the MU100R is reset when receiv-
ing a GM System On or XG System On
message. Generally, this message is automati-
cally transmitted to the MU100R as part of
General MIDI song data. When Mute Lock
is set to off, this resets the Mute status of the
Parts on the MU100R. If you want to keep
the current Mute settings and disable this
reset, set Mute Lock to on. (For more infor-
mation on the Mute function, see page 85.)
A/D Part Lock
Settings:
This determines whether or not the cur-
rent parameter values and Variation ef-
fect 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 Varia-
tion settings of the A/D Parts, set Mute
Lock to on. (This parameter has no ef-
fect in the Performance mode.)
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 original
Equalizer settings. When set to "off," the
Equalizer changes according to incoming
XG/GM System On messages. This setting
affects the Multi mode only, and not the Per-
formance mode.
