Check out this cool iOS (iPhone) music creation app called Figure by Propellerheads.

Very easy to use and get going, in fact, I downloaded it on the train this morning and started making beats straight away. It's an initial release so it can be forgiven for missing a few things I'd like to see such as export/save for the songs you've created and more sequencing.

Still at $0.99 AU, it's a bargain and another tool to add to my music creation arsenal.
