■ Using MIDI to change effect parameters
The 1204 allows the use of MIDI control change messages to change effect parameters. This includes all
parameters except changing the effect type (as performed with the EFFECT selector or BANK switch) and
adjusting the INPUT and OUTPUT level controls. Using control change messages to change effect parameters is
called real-time modulation and differs from the parameter editing process described in the previous section. When
real-time modulation is used, the effect sound as heard in the output changes, but the actual effect settings are not
altered. Consequently, if memory store is carried out in this condition, the same settings as before will be stored.
To change effect parameters via MIDI, proceed as follows.
1. Connect the MIDI OUT jack of the external device to the MIDI IN jack of the 1204.
Turn all devices off before making this connection.
2. When connections are established, turn on the devices and use the MODE key of the 1204 to set it to the
memory mode.
3. Set up the 1204 so that the MIDI receive channels match the MIDI send channels of the external device.
4. Send control change messages from the external device to change effect parameters at the 1204.
Note: The relationship between MIDI control change messages and effect parameters of the 1204 is as
shown below.
Recalling Factory Default Memory Settings
The 1204 is shipped from the factory with 100 recommended effect settings already stored in memory. When the
user stores settings in memory, these factory defaults are overwritten, but they can be restored using the recall
function. The recall mode is a special mode of the 1204 that is separate from the other two operation modes. It
cannot be activated when the unit is already turned on. The unit must be turned off and then turned on by a special
procedure, as described below.
In recall mode, all 100 settings can be restored together, and it is also possible to restore individual settings.
To use the recall mode, proceed as follows.
1. Turn the unit off.
2. Keep the STORE key depressed while turning the unit on with the POWER switch.
3. The indication
AL
"AL" flashes on the display.
4. When wishing to restore all 100 settings together, press the STORE key once more in this condition.
The indication on the display flashes more rapidly. When the recall process is completed, the unit
automatically switches to the memory mode.
5. When wishing to restore only a particular memory number, use the ▲ and ▼ keys to select the desired
number in step 3.
6. When the desired memory number is displayed, press the STORE key. The indication on the display
flashes more rapidly and the contents of that memory number are returned to the factory default.
7. Because the unit does not automatically switch to the memory mode when individual memory numbers
are being restored, it is possible to restore several numbers in succession. When you wish to terminate the
recall mode, press the CANCEL key. The 1204 then switches to the memory mode. Turning the unit off
also terminates the recall mode.
