I can't answer questions about the device's capability... but if you're asking whether or not it is possible to change patches on a sound module in the middle of a song in BIAB, the answer is yes. This would be accomplished by embedding Midi CC program change commands in the song at the place where you want the patch to change

But it sounds like you want to use the pedal to change patches as a completely stand-alone solution. Whether or not that is possible may be a question for the Solton user group.

But, it's worth noting that most sound modules can use MIDI foot pedals to change patches. Usually, foot pedals will let you scroll through the patches in order. Setting it up so the pedal jumps to a specific patch may require changing the patch order or other device programming.

I know this isn't a very helpful reply, but this isn't a question that is easily answered in a forum.
