4-track recording software?

[Jomboni]

My friend has this 4-track software on his iphone that also lets you do very basic mixing on the phone - you can obviously also transfer the recording to your PC to work on it too. He can even hook up a higher quality microphone to the USB port on his phone to get a better recording. He uses is to get halfway decent sounding reference recordings of us at band practice.

Is there anything remotely similar on the Android? If not, would I at least be able to buy a USB mic and use that to record instead of my phone's built in mic?

Thanks!

This guy has created a simple four track recorder app which is rather good! It's open source too, so who knows, other may join in and start to create additional cool features!

It would be great to have an AUX FX send, and whatnot for it!

You can just get it free on Marketplace.
It's called "SONG MEMO".
