Re: Audio and MIDI not recording in sync

Sun Mar 07, 2021 3:10 pm

To sum it up, It seems that the only case when recording timing is correct, is when recording only audio with external zero latency monitoring. MIDI will always get compensated for latency, but not the exact amount, whether it is monitored or not, resulting in offset between MIDI and audio recordings. In fact, any MIDI recordings will always end up with a 'non-correct' amount of compensation. This becomes noticeable with higher latencies and/or when recording audio and MIDI simultaniously. When recording audio through software monitoring, it doesn't get compensated at all.

Re: Audio and MIDI not recording in sync

I have a problem with audio/midi recording sync, but I'm not quite sure whether it is the same problem as described here.

I'm doing live multitrack recording of the whole band, including the audio outputs of the electronic drum kit, 8 tracks total. At the same time, I'm recording the MIDI of the drum kit on a separate track. Set all tracks to recording, press record, 1-2-3-4 and go.
(the intention is to use the drum kit audio, which is so-so, for monitoring (direct through the Behringer XR18 we're using for recording) and then later using the MIDI track for the mix).

MIDI drums and audio drums are not only out of sync initially, but also seem to follow a different clock. At the start of a take the midi drums are much further ahead of the audio than at the end of the take. So the solution of carefully moving the MIDI track in time to sync it up doesn't work...

Any ideas on how I could fix this?

My solution was to jump ship, because of this and the neverending automation and PDC problems. Adjusting the audio recording offset on ad hoc basis can work on a very simple setup, but basically requires trial and error approach.
