Derek,
This is great! I do a lot of recording in my home studio but I've not made the leap to my mobile device yet to see how good these tools are for recording from a tablet or smartphone. I need to get into this though, since I do travel a lot for my day job and I often wish that I had some kind of recording setup that I could take on the road. Are you using an iPad or iPhone for your platform or some kind of Android phone/tablet? (I use both for my work so I could go with either one) I'm guessing that there is more for the iOS platform now since that seems to be the one with the best media apps.
Do you have any favorite midi controllers that you use playing synth parts or do you just use the touch screen?
Thanks,
--Jim
