Hello and welcome! I'm aware of plenty of guitarists that manipulate effects on the fly as part of their style, I think that's why you can buy those big knobs (settle down at the back, yes, you @bad alice ) to allow you to use your foot to adjust the settings, right? There's plenty of space in the market for stuff like this, even if it isn't for me. I'm a Kemper user and I also use a FAMC Liquid Tracks Mp3/Midi player to trigger samples. The Liquid Tracks has the ability to record and send Midi to the Kemper so I've started to automate my expression pedals. For me, the simplicity of pressing a footswitch to trigger a number of sequential changes, CC values and such is a god send; mostly because I'm rubbish at multi-tasking! In fact, if my drummer was prepared to play to a click track, I'd happily automate everything by Midi, expression pedals, patch changes, you name it just so I'd never have to press a button for the whole set. However, I get why that is something that horrifies some! Not sure what I would be able to help but feel free to ask if you can!
