Performance (PFMInit)
One of the four parameters above will be available, depending on
the currently selected Sound Module mode: XG, TG300B, C/M or
PFM. Initializing this parameter restores the original settings for
the selected mode.
NOTES
• For the PFMInit setting, only the currently selected Performance will be initialized.
• For XGInit and GM Init, the initialized settings are the same as when the MU100R is reset
upon receiving an XG System On or GM System On message.
Drum (DrumInit)
Range: DrumS1 — DrumS4
This restores the original drum settings for the selected Drum Setup
S1 — S4. (Use the VALUE -/+ buttons or data dial to select the
desired Drum Setup.)
NOTE
This parameter is not available when the MU100R is set to Performance mode.
