I'm looking at the Source Audio Reflex as an alternative to the Mission Expressionator. I'd like to be able to control other pedals separately and have the Reflex retain the last value for the treadle after I've switched to controlling a new pedal. The demo I've seen shows the Reflex simultaneously controlling a few pedals at once, but doesn't make it clear whether I can provide individual control over other connected pedals while keeping those pedals active. The problem, of course is that what you do for one, you do to them all. I know there is some level of programmability and preset recall, but not sure how that's done, unless it's through midi, which means I need a midi controller to control my expression pedal. It's possible to do this, but an Expressionator just seems a little bit cleaner. Thoughts?
