LOCAL CONTROL (Default: on) /GM mapping (Default: off)
This setting determines whether or not the keyboard and sound source of this
keyboard are connected internally. When recording to a computer or other external
device connected to this keyboard’s MIDI IN/OUT terminal, it helps if you turn
LOCAL CONTROL off.
on:Anything played on the keyboard is sounded by the internal sound source and
simultaneously output as a MIDI message from the MIDI OUT terminal.
oFF:Anything played on the keyboard is output as a MIDI message from the MIDI
OUT terminal, without being sounded by the internal sound source. Turn LO-
CAL CONTROL off whenever you are using the MIDI THRU function of a
computer or other external device. Also note that no sound is produced by the
keyboard if LOCAL CONTROL is turned off and no external device is con-
nected.

sounded by the internal sound source

put as MIDI messages from the MIDI

board’s sound source.
