You seem to be pegged on what current controllers can do... And that's exactly what I am saying: they often suck! But they can improve and I am confident they will. When I am learning a brand new instrument I can literally feel my brain knowing exactly what I want to do way before my fingers/mouth/feet are able to perform the task at hand. How is this not an interface problem? With button controllers the best you'll get is one chord per button with no fine shading of levels, no control over inversions or voicings, and so on. No way. If you don't have to be memorizing stupid things such as "where is the minor 7th again on this one particular instrument?" maybe you could use your free mental cycles (and fingers, feet, mouth) to control that instead... And who knows, maybe you could now do 4-5 inversions in the same amount of time it would take you to do a single one on a piano. Or maybe you can do inversions way more effortlessly on another instrument and focus on really nailing the vibrato. It's absolutely fine to make music like this, but it's not fine to demand that all music be made like this. I never said this, I'm just saying that a lot more can be done with a lot less effort if instrument/controller interfaces improve.
