How to Record Live Musicians Efficiently
If you’re recording real instruments, most of the time it is better to let them finish a take even if it contains some errors. These errors can be later patched from another take or you can use parts of this take to patch another take and maybe even if the first half runs badly, the second half might be the best take you get.
I would only stop a take if something goes really wrong like out of sync musicians not finding their way back together, or massive errors. In the end most of the time, you get more out of not stopping a slightly bad take than doing a re-take. This applies more to longer cues than short cues.
