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-720 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.
1. After having kept the EDIT button pressed, use the
SCROLL
button to show the MIDI Filters page:
2. Use the +/YES and -/NO buttons to choose one of the fil-
ters to be programmed. Here is a list of the available filters:
3. Press the SCROLL
button to move the cursor to the sta-
tus of the selected filter:
4. Use the +/YES and -/NO buttons to change the filter’s sta-
tus. On means that the corresponding data is filtered (not
sent or received), Off means that it is not filtered (it is sent
and received).
5. Press the EXIT button to return to the Main or Song Play
page and save the changes (see “Exit from the Global edit
mode” on page 47), or the SCROLL
button to go to the
next edit page (see below).
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-720, 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-720 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-
720’s internal memory data.
Warning: When you turn the USB connection off, the C-720
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-720 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-720, 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-720’s memory content,
and cause malfunctioning on your personal computer
