That’s not a bad idea, although the whole point is that a company that makes user interfaces (a musical instrument is essentially a user interface for making sound) should, you know, think about user interfaces, not leave it up to their customer base to help them figure out how to make their user interfaces. I could easily say a couple of things: focus on content management during design, not after the fact (Overbridge). Talk to people about fairly straightforward structural storage hierarchies (simple path file specifications). Continue to label things better (MKII models tend toward this direction). Consider making your screens a bit bigger so there is less need for remembering multiple keypresses that are not rationally related to what they do (example, “Function” + “Mix” is a shortcut for unison mode on the A4). Nice to have the shortcut, but doesn’t make sense on its face. Straighten our or add buttons so “Yes” and “No” mean the same thing no matter where you are (sometimes “Yes” means “enter” sometimes it means forward in the menu structure, etc., sometimes it means “toggle” on and off). Not intuitive, at all, when it should be, could be.
I find it very intuitive once you understand the general file structure. Devices as deep and versatile as elektron products will demand some understanding and menu diving. Intuitiveness also is generally closely tied to ones familiarity with something. Riding a bike is generally intuitive, but it takes practice and experience to get there.
