Welcome onboard Derek.

I can't listen to the clip @ work, but I've recently dived head first into iOS recording, firstly with Garage Band on my iPhone, and as of the last 2 weeks, with my sexy new iPad 2.

I've been using Garage Band to assemble song ideas (I use a LOT of imported loops/samples though and GB isn't so great at organizing them) and I've tried Amplitube with the iRig adaptor and am not loving it so far, I very much prefer my 'real' guitar sounds and have a Blue Snowball USB mic on its way to me so I can get those into my iPad

I'm curious though, whilst MultiTrack DAW looks amazing and I'll almost certainly grab it tonight, have you had any experience with amplitube and/or Garage band in iOS based music production? I'd be interested in your thoughts.
