Incomplete. . . Why is there no access to the FULL version? Incidentally, the notation associated with this instrument is not really new. KLAVARSKRIBO is also a 12 note - based system, which is even more intuitive.
I don't like it. It may be good as a concept but it's still easy to play piano.The only advantage is that all scales are going to look alike
Cool idea, but lousy in practice Its just harder to play. Also the app is kinda clunky. Tries to imitate a physical chromatone keyboard rather than optimising for touch screen. Doesn't use full width that it could. Multi touch is buggy.
H Superior to medieval piano concept
Good concept could use some translations for english.
