Diamond Amplification MAC-2 - Manual (Page 10)

Programming
Programming the MAC-2 lets it know which switches to turn on when
you select a program number on your MIDI footswitch. For each
program number on your footswitch, you can choose which channel
and which features are active on your amplifier. For example, you can
set up button 1 on your MIDI footswitch to select channel 2 on your
amp, and button 2 on your MIDI footswitch to select channel 1 and the
boost function.
The MAC-2 is designed to work with any standard MIDI footswitch.
You can store different switch settings for MIDI program numbers 1
through 128. When a Program Change message is received on the
correct channel, the MAC-2 will automatically recall the saved settings
for the given program number.
To program the MAC-2, simply connect your MIDI controller’s MIDI
output to your MAC-2’s MIDI In jack. The MAC-2 is set for MIDI
Channel 1 by default. Either make sure your MIDI controller is set up
to transmit on Channel 1, or use the MAC-2’s setup mode to change
which MIDI channel the MAC-2 responds to. See the Setup Mode
section for more details.
To save a program setting, perform the following steps:
1. Using your MIDI controller, select a MIDI program number.
2. Using the MAC-2 buttons, select the amplifier channel (and
other features) you’d like to assign to that MIDI program.
3. Hold down the Write button on the MAC-2 until the LEDs
flash. This should take about 3 seconds.
That’s all it takes. You can repeat this for any or all of MIDI program
numbers 1 though 128.
So, for example, let’s assume your amp is a two channel amp with a ¼”
jack for channel switching. Follow the following steps to make your
amp switch to Channel 2 when you step on preset 3 of your MIDI
controller:
