MIDI Usage Examples
ZOOM G9.2tt 50
● When module on/off switching is
performed
When the module is set to on, the value 127 of
the control change number is sent. When the
module is set to off, the value 0 of the control
change number is sent.
● When bypass/mute on/off switching is
performed
When bypass/mute is set to on, the value 127 of
the control change number is sent. When
bypass/mute is set to off, the value 0 of the
control change number is sent.
● When pre-amp section channel A/B
switching is performed
When switching to channel A, the value 0 of
the control change number is sent. When
switching to channel B, the value 127 of the
control change number is sent.
■ Example for receiving control
change messages
According to the control change value received,
the G9.2tt status and parameter values change as
follows.
● When control change for expression
pedal 1/2 is received
The value of the parameter assigned to the
pedal changes according to the control change
value (0 – 127).
● When control change for module on/off
is received
If control change value is between 0 and 63, the
module is switched off. If control change value
is between 64 and 127, the module is switched
on.
● When control change for bypass/mute
on/off is received
If control change value is between 0 and 63,
bypass/mute is switched off. If control change
value is between 64 and 127, bypass/mute is
switched on.
● When control change for pre-amp
section channel A/B switching is
received
If control change value is between 0 and 63, the
pre-amp section switches to channel A. If
control change value is between 64 and 127,
the pre-amp section switches to channel B.
Sending and receiving
G9.2tt internal data via
MIDI
The patch data stored in a G9.2tt can be sent and
received as MIDI messages (system exclusive).
When two G9.2tt units are connected via a MIDI
cable, this allows copying of patch data from the
sending unit to the receiving unit.
NOTE
When patch data are received, all existing patch
data in the G9.2tt will be overwritten. Perform the
following steps with care, to avoid accidentally
overwriting important data.
1. Connect the MIDI OUT connector on
the source G9.2tt to the MIDI IN
connector on the target G9.2tt using a
MIDI cable.
(1) When a control change message
is received...
(2) The same operation as when the respective
expression pedal or switch or key at the
G9.2tt is operated occurs.

MIDI Usage Examples
ZOOM G9.2tt 51
The steps at the target G9.2tt and source G9.2tt
are explained separately below.
■ Target G9.2tt
2. Set the G9.2tt to play mode and press
the [AMP SELECT/SYSTEM] key.
Then use the [TYPE] knob to bring up
the “BulkDumpRX” (bulk dump
receive) parameter on the display.
3. Press the [PAGE] key.
The G9.2tt is switched to bulk dump target
operation, and a MIDI message requesting data is
sent repeatedly to the source G9.2tt.
■ Source G9.2tt
4. Set the G9.2tt to play mode and press
the [AMP SELECT/SYSTEM] key.
5. Use the [TYPE] knob to bring up the
"BulkDumpTx" (bulk dump transmit)
parameter on the display.
6. Press the [PAGE] key.
The G9.2tt is switched to the bulk dump source
standby condition. In this condition, the G9.2tt
will automatically send patch data when it
receives a MIDI message requesting data.
While the target G9.2tt is receiving data, the
display changes as follows.
HINT
If you press the [EXIT] key before the indication
"Receiving..." appears, the patch data send/
receive operation is aborted and the previous
display returns.
When the patch data send/receive process is
completed, both G9.2tt units return to the AMP
SELECT/SYSTEM menu.

The web site of ZOOM Corporation ( http://
www.zoom.co.jp ) has editor/librarian software
available for download. Using this software, you
can store patch data of the G9.2tt on a computer.
