Muscle memory’s fine. It’s the “Wait a minute, what was the next part again …”-thing that’s not so good. Or it is, but when playing the piano, I need sheet music to learn the piece, then eventually I don’t, and some of the stuff I learned years ago, I still know by muscle memory.
So I’m suggesting the exact same thing for the Octatrack, just for my own sake, and looking at your picture, I’m thinking this is what I mean.
To each his own, especially in electronic music. But it’d be good for me, and I’m sure one or two out there would benefit from it also.
