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

change or bank select + program change

messages.

There are two ways (program change modes) for

doing this, as described below.

●Direct mode

With this method, you use a combination of

MIDI bank select and program change

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.

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.
