best composing/music app for iphone?

So, are there many good composing/music apps for iPhone?

Preferably I'd like something with a piano-roll style interface for composing.

I see "8bitone Micro Composer" has piano roll .. is it any good?

iSyn is fucking wicked - 2 synths with 2 occilators, 1 LFO etc. the piano roll is pretty intuitive and you can also 'freestyle' with it. i've been meaning to record some of the tracks i made on it. there's also technoBox, which is made by audiorealism - it's a cute 303/808/909 emulator. i used it live once for a laugh.

ok, so i recorded some of the wee tunes i make on the bus;

isyn01.mp3Fetching info...

isyn02.mp3Fetching info...

technobox01.mp3Fetching info...

i like those

cheers. realised recently that the bassline on the first one is like that 'sexy back' song. think i was going for something dopplereffekty... but failed.

eno has an ambient app that i didn't want to put down the one time i had a go on it

ah yeah, looks interesting, but I'm after something more sequencer-like that I can use to sketch out melodies and harmonies

iSyn does look pretty good (thanks idrn) but it looks like you're limited to 2 monophonic synths, so no chords allowed presumably

looks fun though
