Yeah. I know a few people who'd pay for this. And given the rising rise in Android market share AND the new, far more powerful machines coming on-line, it'd be a pity for the developer to avoid such a huge revenue stream merely in order to avoid dev headaches and actually, like, get sleep and have a life.
Seriously, though, some of us musicians would die to have this on Android. Which, of course, presents the problem that if that were the price, we'd be left unable to use it once obtained, since we'd be dead.
Bother. There's nothing for it.
