System Functions (SYSTEM)

The System functions provide various controls of the overall operation of
the MU100, 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 MU100's Voices. It does not affect the
pitch of the individual drum/percussion
sounds of the drum kits. Master Tune is es-
pecially useful for adjusting the pitch of the
MU100 when playing with other instru-
ments. The actual pitch of each Voice de-
pends also on the other pitch related param-
eters: Note Shift, Transpose (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 MU100 is reset when receiving
a GM System On or XG System On mes-
sage. Generally, this message is automatically
transmitted to the MU100 as part of General
MIDI song data. When Mute Lock is set to
off, this resets the Mute status of the Parts on
the MU100. If you want to keep the current
Mute settings and disable this reset, set Mute
Lock to on. (For more information 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 142) 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.
Utility Mode
