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 synchro-
nize to the Timing Clock messages and begin playback from
the current point in the song. In the same way as synchronizing
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-for-
ward or rewind while the song is playing, Song Position Pointer
messages will not be transmitted. Be aware that if you perform
these operations during synchronized playback, the synchro-
nization will be lost. Also, even if Song Position Pointer mes-
sages 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 trans-
mit and receive parameters that are specific to particular de-
vices, such as sound data and editing data.
The system exclusive message format of the EA-1 is [F0, 42, 3n,
51, ... F7] (n: exclusive channel).
However, some system exclusive messages have been defined
for use in a specific way, and these are called "universal system
exclusive messages."
Of the several different universal system exclusive messages,
the EA-1 supports the following one.
- When an Inquiry Message Request [F0, 7E, nn, 06, 01, F7] is
received, the EA-1 will transmit an Inquiry Message [F0, 7E,
nn, 06, 02, (nine bytes), F7] that means "I am a Korg EA-1 and
my system version is ..."
10. Transmitting sound setting
data (Data Dump)
Song, Pattern, or All (song, pattern, global) data can be trans-
mitted as MIDI exclusive data, and stored on an external de-
vice. This data is transmitted by the MIDI mode Dump com-
mand. The channel used for transmission and reception of this
data is set by the MIDI mode MIDI ch setting. Data dumps are
also transmitted when a Data Dump Request message is re-
ceived.
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 EA-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.13).
Sounds or operations are different than when I ed-
ited!
• Did you perform the Write operation after editing? (p.33, 38)
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 or special cable connected correctly?
When playing the EA-1 from an external device
• Has the EA-1 been set to receive MIDI data on the channel on
which the data is being transmitted? (p.41)
• Is the MIDI mode MIDI Channel parameter set to the desired
channel? (p.41)
• Are the MIDI mode MIDI Filter settings set appropriately?
(p.42)
When playing an external device from the EA-1
• Does the MIDI channel of the EA-1 match the MIDI channel
of the receiving device? (p.41)
Cannot write a pattern or song!
• Is the Global mode Protect setting turned "on"? (p.40)
Playing the step keys does not sound the specified
sound!
• After editing the sound of a part, did you perform the Write
operation? (p.33)
• Is the Keyboard function turned on?
• Is a motion sequence being used? (p.29)
