I thought I’d share this. Apologies if it has been posted before, or if it’s too obvious. Here’s how I use Renoise as a multitrack audio looper (sort of):
-Turn ‘auto capture instrument’ on.
-Set up a few tracks, and put a C4 note on the first beat of each track. Use a different empty instrument on each track.
-activate the Sample Recorder window, and activate ‘sync start&stop’ (it works best if you have a key assigned to ‘start/stop recording’)
That’s it. You can now record audio, and the recording will automatically start playing in sync with the pattern. If you want to record a new loop that plays simultaneously, just go to the next track, and start recording again.
I say ‘sort of’ because it has a disadvantage compared to ‘real’ loopers: the recorded loop doesn’t start playing immediately after the recording has ended, you have to wait until the next time the note is triggered. (In the meantime, you can just play the loop again, of course). Still, it’s a lot of fun, especially once you start adding effects. Could be useful in live performances, too.
