I’m having real difficulty getting OB to sync my Rytm with Live.
If I use OB to route my audio and send sync, there is an unacceptable level of jitter, maybe around 6ms total.
So I turn off OB sync and use expert sleepers to send sample accurate MIDI clock to RYTM. This is fine if I take the resulting audio directly from the Rytm’s outputs to my sound card. The latency is constant and jitter is <1ms.
But if I take my audio from OB, the audio shifts around with a latency than starts at around 20ms, and gradually slides down to zero over 10 seconds or more. The jitter is <1ms like this though.
Does this sound familiar, having to wait for over bridge’s audio to catch up with audio coming from the analog outs? If I listen to OB and analog outs simultaneously I can see/hear them coming into sync over ten seconds or so after i start the transport on my DAW.
I’m starting to think I should go back to using a desk…
I dont understand how audio can drift without clicking or something. Wierd, but thats what seems to be happening - OB audio drifts relative to the analog outs.
It’s the clock, not the recording.
Rytm is just playing back at a tempo according to what the DAW’s clock is telling it through the Overbridge communication.
If the clock (or probably in this case, the transmission of the clock via OB) slows down, or speeds up, Rytm plays slower or faster.
That’s why you aren’t getting any clicking.
Its not the clock or response to clock that is drifting. I am using expert sleepers sample accurate clock with ob sync disabled. I am recording the analog outs panned hard left and ob usb audio panned hard right. I can clearly see the ob audio starts with 20ms latency and gradually catches up over ten seconds or so. The audio from the analog outs is bang on from the moment i press play on my DAW. So im guessing the audio itself must be getting stretched by OB during transmission.
I had a very similar issue and couldn’t work it out, I figured the problem was Ableton’s clock. I ended up fixing the issue by using my TR-8 as the clock and having Ableton track that, not it’s internal clock. The subsequent issue was that my TR-8 then started suffering -15ms latency compared the rest of my set up. So I delayed the track I record my TR-8 on, and now my set up is tighter with only a slight midi jitter. Hope that can help you
In summary, using Ableton and OB exclusively to sync is very, very, very very very unstable.
Sometimes there is something weird with audio via overbridge and the sync.
I recorded a track. OT was masterclock, sending sync to AR and A4. OT recorded via soundcard, A4 + AR via Overbridge in Ableton. OT was sending Midi to Korg Volca Bass. Korg Volca Bass was sending audio to A4 ext. in.
So I performed a huge break in the track Unmuted the bassdrum, tweaked some knobs and the AR went ot of sync for 2 or 3 bars.
