Interesting question. Depends on what your controller will send. You won't be able to assign one button to alternate between A and B of any/all modules on "the fly" because each channel is obviously a different "note" number. Might be a question for the pedal maker? Do you mean DMC Pro or is this a different controller?
From the owner's manual:::
CHANNEL SWITCHING:
If there are four preamps installed, pressing & releasing the Channel Select switch within half-a-second will change the channel from 1 to 2, pressing & releasing again 2 to 3, and again 3 to 4, etc.
DIP SWITCH SETTINGS:
On the rear panel you will find a dip switch for setting up the midi/channel switching parameters. The unit is shipped set up to receive program change data on midi channel one. This setup is compatible with most standard setups. Should you have some specialized needs, the following paragraphs should provide the information you need.
The M4 “reads” the DIP switch positions only on power up. Whenever a change is made to any dip switch, the M4 must be powered off and back on to “read” the change.
DIP SWITCH SETTINGS:
Using a pen or similar pointy device, move the eight small switches ON or OFF according to your specific needs. See below for the switch functions.
S1 through S4 are used to set the midi channel (1 -16) that the M4 will receive data on. See the chart below.
CHAN. S1 S2 S3 S4
1 OFF OFF OFF OFF
2 ON OFF OFF OFF
3 OFF ON OFF OFF
4 ON ON OFF OFF
5 OFF OFF ON OFF

S5 is used to activate the “omni” mode. “Omni” is a special mode that allows the M4 to receive data on all 16 midi channels simultaneously. Turning the omni mode on overrides S1 through S4. Set actuator 5 ON to turn the “omni” mode on or up for off.
S6 is the “Program change enable” function. This is the most common mode of operation that allows the M4 to receive program change (patch) commands from your midi controller. Set this switch down for on or up for off.
S7 is the “Controller data enable” function. Activating this mode allows the M4 to respond to instant access data from midi controllers. Below are the “note / controller” numbers that will turn on the modules.
Note Module
#56 ……… 1A
#57 ……... 1B
#58 ……… 2A
#59 ……… 2B
#60 ……… 3A
#61 ……… 3B
#62 ……… 4A
#63 ……… 4B
#64 ……… MUTE ALL
S8 has no function at this time.
