Hi, maybe this is stupid question, but I wonder if this is possible in Renoise? 
what?
I meant set a sound file looping and then trigger another sound file while the first is still playing and overdubbing, recording, reverse over the first one and so on. And you do that everything live. You know, like in mobius VST or sooper looper I think 
Yes, it is possible.
