Any pro music apps for android?

[doclee07]

I am a musician looking for suggestions for music apps for professional use. I know that the "i" gadgets have a lot of things out (iRig, recording software, composition software) but I haven't seen anything for the android platform. Suggestions other than moving to the Apple products?

I also wonderd this. Not that it would be great recording quality. I would like a multi track editing program.

Something that records as well. Just for fun.
