Diamond Amplification MAC-2 - Manual (Page 11)

1. Plug a ¼” cable into Switch 1 on the MAC-2 and the jack for
your channel switching on your amp.
2. Make sure your MAC-2 is connected to your MIDI controller
with a MIDI cable.
3. Using your MIDI controller, step on preset 3.
4. Using the MAC-2 buttons, press Switch 1. The LED will light
up and your amp will change channels.
5. Hold down the MAC-2’s write button until the MAC-2’s
LEDs flash.
6. That’s it! Test your setting by stepping on another preset,
make sure the Switch 1 LED is not lit on the MAC-2 (if it
remained on, manually press the switch), then select preset 3
on your MIDI controller. The Switch 1 LED should light up
and your amp should switch back to Channel 2.
7. Repeat these steps for all of your presets.
Remember, the MAC-2 remains in the last state you put it in. So if
you step on a preset that activates a switch, it will stay activated
until you tell it to do something else. So when programming your
MIDI controller, you should repeat these steps for every preset,
even if it seems duplicative.
If the LEDs don’t flash after a few seconds of holding down the Write
button, it means that your MAC-2
did not receive the MIDI Program
Change message. Check your MIDI cable connection, and make sure
that the MIDI controller and MAC-2
are set to the same MIDI channel.
Now that your settings have been saved, you can recall your settings by
pressing the appropriate button on your MIDI footswitch. The MAC-2
will call up your saved settings and set the switches whenever it
receives a MIDI Program Change message.
Continuous Controllers
In addition to supporting MIDI Program Change messages, the MAC-2
supports MIDI Continuous Controller messages. This allows you to
have direct access to each switch. If your MIDI footswitch supports
Continuous Controllers you can, for example, assign one button on
