■ Local Control
......................................................................................................................................................
“Local Control” refers to the fact that, normally, the PSR-520 keyboard
controls the internal tone generator, allowing the internal voices to be
played directly from the keyboard. This situation is “Local Control ON”
since the internal tone generator is controlled locally by its own keyboard.
Local control can be turned OFF, however, so that the keyboard does not
play the internal voices, but the appropriate MIDI information is still trans-
mitted via the MIDI OUT connector when notes are played on the key-
board. At the same time, the internal tone generator can respond to MIDI
information received via the MIDI IN connector. This means that while an
external MIDI sequencer, for example, plays the PSR-520 internal voices,
an external tone generator can be played from the PSR-520 keyboard. The
default Local Control setting is ON.

■ Initial Data Send
...........................................................................................................................................
Transmits all current panel settings to a MIDI data storage device before
actually recording your performance. With the “InitSnd?” function selected,
press the [+/YES] button to start transmission. When the data has been
transmitted, “End” will appear momentarily on the display and return to the
“InitSnd?”.
• The song data will not be played
back correctly, if the panel set-
tings for the song has not been
recorded in advance. To record
the panel settings to an external
device, engage the external
device in the record mode and
execute the Initial Data Send
operation.
• The “InitSnd?” function can be
quickly selected by pressing and
holding the [SYNC-START/
STOP] button.
■ External Clock
..................................................................................................................................................
Reception of an external MIDI clock signal can be enabled or disabled as
required. When disabled (OFF), all of the time-based functions (Auto Ac-
companiment, SONG recording and playback, etc.) are controlled by its
own internal clock. When MIDI clock reception is enabled (ON), however,
all timing is controlled by an external MIDI clock signal received via the
MIDI IN terminal. The default setting is OFF.
Overall Functions
• If the External Clock function is
turned ON but the external clock
signal is interrupted for more than
400 milliseconds, the internal
clock is re-selected automatically.
• External Clock setting is retained
in memory even when the power
switch is turned OFF, as long as
batteries are installed or an AC
adaptor is connected.
• When the External Clock is
turned ON, the song recording/
playback will be controlled by the
external device.
