Ableton Live: midi and audio?

[ml@dadaprod.org]

is it possible with AL to record live and synchronise, Midi notes and audio
signal..

I mean at least two loops (a midi and an audio one), that will be 
synchronised
in AL.. the midi loop could be related to several Vst instruments, and the
audio could be used to sample acoustic or electric signal (guitar, drums 
etc..)

cheers
