Creative musical exploration
When I first watched the videos for this app, I was a bit put off,as it seemed like a lot of tapping to get ideas going. I couldn't have been more wrong. The controls are minimalist, and there's a bit of a learning curve: it takes a bit to remember when you should be double tapping, flicking, triple tapping, or tap-and-holding, but once you have that down, there's a definite workflow that is very smooth and fast.
I wouldn't call this a "serious" music app. It has a few limitations which make it a four-star app (limited sounds, no record or export) However, if you enjoy building and layering musical ideas, don't hesitate, you'll enjoy this app.
