I have the Catalyst 60. I use an iPad for lyrics/chords with an app called "UnrealBook" and this app will let you send midi messages over USB. I use the Apple camera connection dongle into the lightning port on the iPad, and a midi cable into that and then into the Catalyst 60. After I've decided what preset I want to use for a song, I put that midi info into the page for that song. So when the lyrics/chords pdf comes up, the amp automatically changes to that amp preset I've got set up, including whether I want the effect on or off.
Alternatively, if you didn't need the lyric/chord charts, you could just set up a pdf for each particular preset, name the pdf for the preset, put them in a "setlist" which would simply be blank pages with the midi preset information in them.
No foot control, but I hope that helps.
