John Holdsworth’s SoundMatrix (App Store link) is a free iPhone version of the ToneMatrix Flash Application, by Andre Michelle, that allows you to create music sequences on your iPhone.

SoundMatrix builds on ToneMatrix, though, letting you  email your creations to your friends or submit them to an online gallery.

SoundMatrix is a 16 note sine wave sequencer. There is also a two track drum kit to bring your compositions to life.

Tap on the display to add notes to the seqence. For Best results add individual notes gradually to build your composition. Tap undo remove the last notes added or clear to start again. To save a composition use the email button to send it to yourself for posterity.
