Just got Ableton Live 6 for my mac, and was messing around with it with my Dad this weekend. He plays the accordian very well, so I thought I’d have a go at recording him and giving him a backing band. Since I can only record one track at once, I tried to get him playing to a click track, but this turned out to be a bit of an effort since he has to play with a band to keep time (and I’m useless, I’ve got no rhythm at all). I ended up just letting him play how he wanted and not worrying about tempo etc. This meant that loops were tricky to do, so I gave up on that, stuck the guitar and bass on, and let him tap out the drums on the keyboard himself 
It’s all pretty much first take so it’s a bit scrappy, but I’m quite happy with it! Naturally, my Dad is astounded by technology these days. Took about an hour all in all.
