MIDI Filters
When you choose a sound, operate the damper pedal, adjust
the level balance in Layer mode, or make other adjustments on
the control panel, a MIDI message is sent to a connected exter-
nal MIDI (and/or USB) device. At the same time, C-520 can
receive a MIDI message from an external MIDI (and/or USB)
device connected to its MIDI IN (or USB port), to control the
sounds, damper pedal, volume adjustment, and other data.
You can choose to deactivate (i.e., “filter”) these data selective-
ly, to avoid unwanted changes or mixing data generated by ex-
ternal devices and internal controls. Also, you could want to
avoid sending MIDI data to an external MIDI device, for ex-
ample Program Change message selecting unwanted sounds
on a different musical instrument.

Data transfer via the USB port
The USB is a high-speed data port installed on most modern
computers. You can use it to transfer data from the internal
memory of the C-520, to a computer and vice-versa. Before
you do this, you must enable USB connection for data transfer.
Note: While data transfer is active, no MIDI over USB communi-
cation is allowed.
Windows ME, 2000, XP, and Mac OS 9.0.4 to OS X, are sup-
ported with no need for special drivers. To use the C-520 with
Windows 98SE you need the dedicated KORG Driver, a special
software that you can freely download from our website.
Warning: Since activating the USB port for data transfer au-
tomatically deactivates MIDI over USB, exit from any MIDI
software on your personal computer before turning the USB
Connect function on. Failing to do so could damage the C-
520’s internal memory data.
Warning: When you turn the USB connection off, the C-520
will be reinitialized and all unsaved data in the instrument’s
memory will be deleted. Save any unsaved sound, perfor-
mance, song, or global setting, before activating the USB
connection.
1. First of all, connect the C-520 to a personal computer via a
standard USB cable. Make sure that the connector is ori-
ented correctly, and insert it all the way into the jack.
2. Then, turn USB Data Connect on on the C-520, to let the
computer see its internal memory as a USB disk.
After having kept the EDIT button pressed, use the
SCROLL
button to show the USB Connect page:
3. Press the +/YES button to activate data connection. The
Disable command will appear in the display.
Warning: Do not press the -/NO button while transferring
data, or you could damage the C-520’s memory content,
and cause malfunctioning on your personal computer
