Don't know who Skrillex is? It doesn't matter. The point is, you can now make and create beats and tunes using your iPhone! The two I have discovered are as follows:

1. Figure - as for now, just for iPhone

2. NodeBeat - for iPad and iPhone

NodeBeat HD 1.5 - iOS Music Sequencer from AffinityBlue on Vimeo.

The only reason I really point these two out are for design and functionality purposes but I'm sure there are more apps than anyone will ever care to download or use.
