Step 14. MIDI
What is MIDI?
MIDI stands for Musical Instrument Digital Interface,
and is a world-wide standard that allows a variety of
musical information to be exchanged between elec-
tronic musical instruments and computers.
1. MIDI connections
Special MIDI cables are used to transmit and receive
MIDI messages. Connect these cables between the
MIDI connectors of the D12 and the MIDI connectors of
the external device with which you wish to exchange
data.
MIDI IN connector: MIDI messages from another
MIDI device are received here. Connect this to the MIDI
OUT connector of the external device.
MIDI OUT connector: The D12 transmits MIDI mes-
sages from this connector. Connect this to the MIDI IN
connector of the external device.
MIDI channel settings
MIDI uses sixteen channels (numbered 1–16) to trans-
mit information directed to multiple MIDI devices over
a single MIDI cable. If MIDI messages are being trans-
mitted on MIDI channel “1”, the messages will not be
received unless the receiving device is also set to MIDI
channel “1.”
2. MIDI messages used by the D12
Note, aftertouch, velocity, pitch bend: This data is
used by the D12 to control effects.
Program change: This data is used by the D12 to select
scenes.
Control change: This data is used by the D12 to control
mixer parameters.
MMC (MIDI Machine Control): MMC messages can be
transmitted to control an external sequencer or
recorder. MMC messages can also be received to control
the D12 from an external sequencer or recorder.
MTC (MIDI Time Code): MTC messages can be trans-
mitted to cause an external sequencer or recorder to
operate in synchronization with the D12. MTC mes-
sages can also be received to synchronize the D12 with
another device.
About the MIDI implementation chart
The owner’s manual of each MIDI device contains a
MIDI implementation chart. This chart makes it easy
for you to verify the MIDI messages that the device can
transmit and receive. When using two MIDI devices
together, compare their MIDI implementation charts to
verify the types of MIDI message that they are able to
exchange.
* For more details on the MIDI specifications, refer to
the separate MIDI implementation. To obtain the
MIDI implementation, please contact your Korg
dealer.
3. Using MIDI
Controlling the D12 from a MIDI sequencer
Here’s how the MMC messages transmitted from a
MIDI sequencer can be used to stop/play/fast-for-
ward/rewind/record/locate the D12.
You must use a MIDI sequencer that supports
MMC. These following operations are not possible
with a sequencer that does not support MMC.
1 Make MIDI connections.
Use a MIDI cable to connect the MIDI OUT connec-
tor of your MIDI sequencer to the [MIDI IN] con-
nector of the D12.
2 Make settings on your MIDI sequencer so that it
will output MMC messages to control external
devices.
For details refer to the owner’s manual for your
MIDI sequencer.
3 Turn on MMC reception.
In the [SYSTEM] “MMC” tab page, set “SelectM-
MCMode” to “Receive.”
4 Set the device ID settings to match.
Set “MMCDevID
” to the same setting as the MMC
device ID of your MIDI sequencer.
Since the device ID specifications may differ
depending on the type of your MIDI
sequencer, it may not be necessary for the
number to be the same.
5 Operate your external MIDI sequencer.
When you perform stop/play/fast-forward/
rewind/record/locate operations on your MIDI
sequencer, the D12 will be controlled accordingly.
(For details refer to the owner’s manual for your
MIDI sequencer.)
At this time, you can also make the D12 trans-
mit MTC (MIDI Time Code) or MIDI Clock
messages to synchronize the MIDI sequencer,
so that the two devices will be synchronized as
the sequencer controls stop/play/fast-for-
ward/rewind/record/locate operations on the
D12.
