5. Turn parameter knob 1 to select the
MIDI channel (1 – 16) on which the
G9.2tt will send MIDI messages.
6. When the setting is complete, press
the [EXIT] key to exit the AMP
SELECT/SYSTEM menu.
The indication “Store... ? ” appears on the display,
to allow you to store the changes.
7. Press the [STORE/SWAP] key to save
the changes.
The MIDI channel setting is accepted, and the
unit returns to play mode.
In the above condition, only the [STORE/SWAP]
and [EXIT] keys are active. By pressing the
[EXIT] key, you can abort the changes and return
to play mode without saving.
Sending and receiving
patch switching
information via MIDI
(program change)
You can send and receive patch changing
information of the G9.2tt via MIDI as program
c h a n g e o r b a n k s e l e c t + p r o g r a m c h a n g e
messages.
There are two ways (program change modes) for
doing this, as described below.
● Direct mode
With this method, you use a combination of
M I D I b a n k s e l e c t a n d p r o g r a m c h a n g e
messages to specify the patch. In the factory
default condition, all patches of the G9.2tt are
assigned a MIDI bank number and MIDI
program change number. These can be used to
directly specify each patch.
HINT
• Bank select is a MIDI message type for
specifying the sound category of a synthesizer
or similar. It is used in combination with program
change messages.
• Normally, bank select is specified in two parts,
using the MSB (most significant bit) and LSB
(least significant bit) value.
● Mapping mode
With this method, you use only the MIDI
program change messages to specify the patch.
A program change map is used to assign
program change numbers 0 – 127 to patches,
and patches are then selected using the
mapping information. With this method, a
maximum of 128 patches can be specified.
■ Enable program change send/
receive
The procedure for enabling send/receive of
program change (+ bank select) messages is
described below.

MIDI Usage Examples
ZOOM G9.2tt 45
1. In play mode, press the [AMP
SELECT/SYSTEM] key.
2. To enable the G9.2tt to receive
program change (+ bank select)
messages, turn the [TYPE] knob to
bring up the “MIDI PC Rx” (receive
program change) parameter and turn
parameter knob 1 to select the “ON”
setting.
3. To enable the G9.2tt to send program
change (+ bank select) messages,
turn the [TYPE] knob to bring up the
“MIDI PC Tx” (send program change)
parameter and turn parameter knob 1
to select the “ON” setting.
4. When the setting is complete, press
the [EXIT] key to exit the AMP
SELECT/SYSTEM menu.
The indication “Store... ?” appears on the display,
to allow you to store the changes.
5. Press the [STORE/SWAP] key to save
the changes.
The setting is accepted, and the unit returns to
play mode.
In the above condition, only the [STORE/SWAP]
and [EXIT] keys are active. By pressing the
[EXIT] key, you can abort the changes and return
to play mode without saving.
■ Using direct mode
By using a combination of MIDI bank select and
program change messages, you can specify a
patch directly.
NOTE
Before carrying out the following steps, verify that
the send/receive MIDI channel setting of the G9.2tt
is as required (
→ p. 43), and that send/receive of
program change messages is enabled ( → p. 44).
1. In play mode, press the [AMP
SELECT/SYSTEM] key.
2. Turn the [TYPE] knob to bring up the
“MIDI PCMODE” (program change
mode) parameter.
3. Verify that “DIRECT” is selected as
program change mode.
If not, turn parameter knob 1 to change the
indication to “DIRECT”. This enables direct
selection of patches using bank select and
program change messages.
HINT
For information on which bank number/program
change number is assigned to each patch, see the
list at the end of this manual (→ p. 79).
4. When the setting is complete, press
the [EXIT] key to exit the AMP
SELECT/SYSTEM menu.
