All Part Control; Editing In All Part - Yamaha MU50 Owner's Manual

MULTI MODE

All Part Control

The All Part controls include: Device Number, Master Volume, Reverb Re-
turn, Chorus Return, Variation Return and Transpose.
Keep in mind that these controls affect all Parts equally, and either add
to or subtract from their individual values. For example, if Note Shift on
one Part is set to –12, and Transpose (in All Part) is set to +12, that Part's
pitch value will actually be 0 or normal.
Selecting All Part Control
To select All Part control, press both PART q buttons simultaneously. (or
press the EXIT button). ("All" appears in the PART section of the display.)
