Im just gonna put it here since I've got no time for doing it myself.
What about an app for your phone where you could patch with all the basic objects for max, but. The patch wont work of course, it will only be visual. And The only thing it'll report if You get "feedback" in The code.
Im constantly sketching on papers. After using max for a while you'll ger that point where You can patch in your head. You know how it'll sound, sort of. It would be super to do it in the phone.
