Song Position Pointer indicates the location at which the se-
quencer is currently stopped. When Song Position Pointer is
received in Song mode by a slave device (i.e., a device whose
Clock is set to EXT), it will change the location at which its
song is currently stopped to match the location of the master.
However on the EM-1, the length of each pattern may be dif-
ferent, so the master and slave will not necessarily be in the
same location. When the Start/Pause key is pressed on the
master device, a Continue message is transmitted, and the song
will begin playback from the currently selected position. When
the slave device receives the Continue message, it will syn-
chronize to the Timing Clock messages and begin playback
from the current point in the song. In the same way as syn-
chronizing the playback from the beginning of the song, you
can specify the location at which playback will start, and then
playback in synchronization. If you use the dial or Select keys
to fast-forward or rewind while the song is playing, Song Po-
sition Pointer messages will not be transmitted. Be aware that
if you perform these operations during synchronized playback,
the synchronization will be lost. Also, even if Song Position
Pointer messages are received during playback, the playback
location will not change.

About system exclusive messages
Manufacturers are free to use system exclusive messages in
any way they choose, and these messages are used mainly to
transmit and receive parameters that are specific to particular
devices, such as sound data and editing data.
The system exclusive message format of the EM-1 is [F0, 42,
3n, 61, ... F7] (n: exclusive channel).
However, some system exclusive messages have been defined
for use in a specific way, and these are called "universal sys-
tem exclusive messages."
Of the various types of universal system exclusive message,
the EM-1 supports the following two.
• When an Inquiry Message Request [F0, 7E, nn, 06, 01, F7] is
received, the EM-1 will transmit an Inquiry Message [F0,
7E, nn, 06, 02, (9 bytes), F7] that means “I am a Korg EM-1,
my system version is ...”
• When a Master Volume [F0, 7F, nn, 04, 01, vv, vv, F7] mes-
sage is received, the volume of the entire system will change.
The exclusive channel is the same as the MIDI channel of synth

10. Transmitting sound setting
data (Data Dump)
Song, Pattern, or Global data can be transmitted as MIDI ex-
clusive data, and stored on an external device. This data is
transmitted by the Global mode Dump command. The chan-
nel used for transmission and reception of this data is set by
the Global mode MIDI ch setting. Data dumps are also trans-
mitted when a Data Dump Request message is received.
11. Editing sounds etc.
By sending MIDI exclusive data dumps, you can rewrite all
patterns or individual programs. By using NRPN messages in
Pattern mode, you can edit the knobs that are active for each
part.
Troubleshooting
The display does not light up when I press the
Power switch!
• Is the AC adapter connected?
• Is the AC adapter plugged into an AC outlet?
No sound!
• Is your amp, mixer, or headphones connected to the correct
jack? (Can you playback a pattern? If so, the connections
are correct.)
• Are your amp or mixer powered-on and set correctly?
• Is the master volume knob of the EM-1 raised?
Sound does not stop!
• When a pattern is played back, it will continue playing re-
peatedly. When you are finished listening to a pattern, press
the Stop/Cancel key (p.14).
Sounds or operations are different than when I
edited!
•
Did you perform the Write operation after editing? (p.41, 45)
After you have edited, you must perform the Write opera-
tion before switching songs or patterns, or turning off the
power.
• Did you edit the selected pattern or song after writing it?
Can't control via MIDI!
• Is the MIDI cable connected correctly?
When playing the EM-1 from an external device
• Has the EM-1 been set to receive MIDI data on the channel
on which the data is being transmitted? (p.47)
• Is the Global mode MIDI Channel parameter set to the de-
sired channel? (p.47)
• Are the Global mode MIDI Filter settings set appropriately?
(p.47)
When playing an external device from the EM-1
• Does the MIDI channel of the EM-1 match the MIDI channel
of the receiving device? (p.47)
Cannot write a pattern or song!
• Is the Global mode Protect setting turned "on"? (p.48)
Playing the step keys does not sound the speci-
fied sound!
• After editing the sound of a part, did you perform the Write
operation? (p.41)
• Is the Keyboard function turned on?
• Is a motion sequence being used? (p.34)
