I use three midi expression pedals connected to a Morningstar controller. (Pictures in the attached)
The only thing you will really lose in this setup in alternate tunings but to me its worth it to not have to carry an extra hardware device.
Midi Guitar 2 is the way to go. As regards synth tones, I like the Roland ones (Roland Cloud Manager) and the Arturia ones. The Rolands are close to what you are used to. Hit me up if you want to pursue this. I’m pretty familiar with it now.
