However, exporting your work can only be done in the proprietary ReBirth format or as a low-quality MP3, which is a serious shortcoming. Also, the multitude of controls available are difficult to get to grips with on a touchscreen, especially on the iPhone version.

Figure, like ReBirth, is the work of Propellerhead Software, and is brand new to the App Store. Costing 69p, Figure is designed to be easy for first timers to get to grips with, letting you program Drums, Bass and Lead Synth on the move.

It is very easy to use and sounds great, though unfortunately there is no export function whatsoever.
