23. System exclusive messages
Since these messages can be used distinctively by each manufacturer, they are used mainly to transmit and
receive data that is unique to particular models, such as sound data parameters and editing data.
The SGproX’s system exclusive message data format is [ F0, 42, 3n, 4B, ff, ...., F7 ] (n: Global MIDI
channel, ff: function code, or type of message).
However, some system exclusive messages have been defined for general use, and these are called Universal
System Exclusive messages.
The SGproX can use the following four universal system exclusive messages. However, 1), 3) and 4) is
transmitted and received, and 2) are only transmitted.
1) When an Inquiry Message Request [ F0, 7E, nn, 06, 01, F7 ] message is received, the SGproX will
transmit an Inquiry Message Reply of [ F0, 7E, nn, 06, 02, (9 bytes), F7 ] which means “I am a Korg
SGproX, with system version ...”
2) When a GM System On [ F0, 7E, nn, 09, 01, F7 ] message is transmitted from the SGproX, a connected
GM-compatible tone generator will be initialized for GM.
3) When a master volume message [ F0, 7F, nn, 04, 01, vv, mm, F7 ] (vv: lower value byte, mm: upper value
byte, in combination representing a range of 16384 values) is transmitted from the SGproX, the volume
of a receiving device can be adjusted without disturbing the balance between timbres of the combination,
or the volume balance between tracks of a song.
4) When a master balance message [ F0, 7F, nn, 04, 02, vv, mm, F7 ] (vv: lower value byte, mm: upper value
byte, in combination representing a range of 16384 values where 8192 is the default setting and lower
values will move toward the left) is transmitted from the SGproX, the stereo position of a receiving
device can be adjusted without disturbing the relative panning for timbres of the combination, or the
relative panning between tracks of a song.
Details of the above are given in the
SGproX MIDI Implementation section.
Consult your local Korg distributor for more information on MIDI IMPLEMENTATION.
24. Transmitting data such as sound settings (Data Dump)
Data for programs, performances, and global settings can be transmitted as MIDI exclusive data, and stored
on an external device.
Transmission of this data is performed in the Global mode

DATA DUMP

page.
This data will also be transmitted in response to a dump request message.
This data is transmitted and received on the Global MIDI channel.
For details on the data, refer to the
SGproX MIDI Implementation section.
Consult your local Korg distributor for more information on MIDI IMPLEMENTATION.
25. Connecting external devices
An external device can be connected in the following ways to play the SGproX.
●
MIDI messages from the external device can play the SGproX in Program mode. Use Program Change
messages [ Cn, pp ] (pp: program number) to select overall settings (program, level and effects etc.) by
switching programs.
●
MIDI messages from external device can play the SGproX in Performance mode (using the SGproX as a
two-timbre tone generator).
In either case, messages will be received on the Global MIDI channel.
