Hi folks, new to this forum and also relatively new to digital recording. I'm curious if anyone knows of a way to do basic multitrack recording using an Android smartphone (I have a Samsung Galaxy S2). I'm looking for the capability to record from an externally connected mic or instrument, the ability to record at mic or line levels, and the ability to bounce tracks.

Put another way - I'm looking for a way to do on my smartphone the kinds of simple recordings I do on my old Tascam 4-track :)

I'm a recording novice at best, so it may be that this is simply not possible, but I figured I'd ask. If anyone has any advice to offer, I'd be grateful.
