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
9. 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
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-
