I’ve been using ImageLine Minihost Modular to play live w/ my band. It worked very well for a while, I was able to run multiple controllers and wire everything as needed. I ran into a problem where Minihost was filtering out all PC messages which is how Amplitube changes presets so this made it a no go.
I then was searching for another live host and ran across Cantabile. I grabbed the free version and it worked perfectly. I was able to insert Amplitube, Tyrell Synth, and GLoop into Cantabile and route both Amplitube and Tyrell to GLoop so regardless of what I was playing I could loop/overdub.
I then decided that this was really cool and I wanted to see what the Solo version was like so I started that trial. The setlist feature is just so fantastic its ridiculous. I was able to create a “template” song that had Amplitube, Tyrell and GLoop already configured. The trick I did in the template was to use 4 pizMidi midiProgramChange plugins so I could set my pedal controller to always send PC 1-2-3-4 for the switch buttons, but the midiProgramChange plugin lets me change the PC number sent so in Amplitube I can simply set the presets I’m interested in using to those PC numbers and very easily get 4 full presets per song.
I use 3 controllers, Arturia Minilab and Line 6 FBV Shortboard and FBV Express. The bank up and down on the shortboard control navigate the setlist, the ABCD buttons choose a preset. I’ve globally mapped the two rocker pedals to a WAHWAH and a Volume pedal in Amplitube and the other 4 buttons on the Express control GLoop, record/overdub, play/stop, undo, and reset. That still leaves me 7 foot buttons for Amplitube preset specific control.
This is like a dream come true 
I love gigging with my MS surface pro for guitar direct to the PA, unlimited sounds, nothing to lug around. I will definitely be buying Solo this month.
Question though, if I get Solo now, and then later try Performer, is there a discounted upgraded?
EDIT:
If anyone is interested in a more thorough explanation or screenshots let me know I’d be happy to take the time.
