The problem with linnstrument and similar things is exactly equality of any note, it's not easy to think like "ok, here we move to another key, so we have to add one sharp here" on a controller like that. For me, even on a guitar I have to "see" the notes to play well and understand what I'm playing, so I had to learn "white keys" on the fretboard, and on top of that, learn octave numbers for each note, only then it really works for me and it's still hard compared to the keyboard where you see all sharps and flats and can treat them as you like. That's more important than using the same muscle memory imo

Fighting notation is like fighting piano keyboard which is also extremely convenient thing to play compared to other stuff, even to grid controllers.
