Best Audio/Music Composition App Yet

I have downloaded and auditioned almost every music comp app available for iPod touch. This iSampler app has the best features for anyone serious about multi-track recording, editing,mixing, and saving on the ipod and iPhone.
Really? I can add effects and edit waveforms on recordings I make with the ipod or import?!! Im creamin!
Really! This is a serious and well written tool for any musician or audio engineer.
Get it and see for yourself!
