You could use automations for this. Set up two tracks with AmpliTube 5 one with each preset. Then use an automation (if CW has a mute operation use that if not use a volume) at the start. On one track you turn on mute, and turn it off for the other track. Then you reverse that when you get to measure 12 and reverse it again at measure 22.
If that's confusing
here's a 15-min video that will walk you through the idea using Reaper. Then you can do something almost identical with volume on Cakewalk and this
two-minute video demos a couple of ways to do it.
In Reaper if you just arm the track and use play you can practice and hear this in action. That is, you don't have to record to get the functionality.
