Receive System Exclusive (RcvSysExcl)
This determines whether System Exclusive messages are received or
not. System Exclusive messages are data specifically (or "exclu-
sively") related to the MU90R. The On setting allows these mes-
sages to be received. This should be to On when receiving bulk data
from a MIDI data storage device. (See page 119.)
Receive Bank Select (RcvBankSel)
This determines whether Bank Select messages are received or not.
Bank Select messages can be sent from another MIDI device to
change the banks of Voices on the MU90R. (See page 42.) The On
setting allows Bank Select messages to be received.
Contrast
This determines the contrast of the display. Adjust this as necessary
for optimum visibility. (At extreme settings, the display may not be
readable.)
