System real-time messages
Active Sensing [FE]
This MIDI message is used to deal with troubles when you’re performing, such as when the transmit-
ting device is turned off, or when the MIDI cable is unplugged or disconnected while you’re playing. If
more than 300 msec passes without an active sensing message being received, the instrument deter-
mines that there is some problem with the MIDI cable, and turns off all MIDI notes as well as resets
the controller values.
Timing Clocks [F8]
This message is transmitted and received to synchronize this instrument with another MIDI device.
The Grandstage X automatically synchronizes with an external device if it receives a dynamic clock
from that device. When no dynamic clock is received, this instrument uses the internal tempo to
transmit dynamic clocks.
System exclusive (SysEx) messages
In addition to channel messages that handle performance data, MIDI also offers messages for trans-
mitting and receiving information, control commands, and settings between MIDI devices. These mes-
sages are called “system messages”.
A subset of system messages includes MIDI messages that manufacturers can use to expand the func-
tionality of MIDI in unique ways. These messages are called “system exclusive messages”. The
Grandstage X can’t be used to transmit or receive system exclusive messages.
Universal system exclusive messages (non-real-time)
Some system exclusive messages have standardized uses that are publicly released. These are called
“universal system exclusive” messages.
The Grandstage X supports the following five universal system exclusive messages.
- Inquiry Message Request
[F0, 7E, nn, 06, 01, F7]
3rd byte nn: Channel
= 0 - F: Global Channel
= 7F: Any Channel
- Inquiry Message
[F0, 7E, 0g, 06, 02, (9 bytes), F7]
When an Inquiry Message Request is received, an inquiry message that states “this is a KORG
Grandstage X, system version XXX” is returned.
[F0, 7E, 0g, 06, 02, 42, 6C, 01, 07, 00, vv, ww, xx, 00, F7]
3rd byte g: Global Channel
6th byte 42: KORG ID
7th byte 6C: Grandstage X series LSB ID
8th byte 01: Grandstage X series MSB ID
9th byte 07: Grandstage X member code
11th byte vv: System Version 1st (1 -)
12th byte ww: System Version 2nd (0 -)
13th byte xx: System Version 3rd (0 -)
(i.e. Version 1.0.2: vv=01, ww=00, xx=02)
