I’m aware of the description in the online manual: “If this is activated, the plug-in latencies are taken to account during recording”
I’ve also perused a few threads on this, that mention it specifically adjusts for latency due to any plugins on input track.
But here’s why I’m after some clarification…
Been having real trouble recording guitar parts recently - takes that I would have sworn were dead locked into the groove, when listening back, the timing sounds off. Nothing awful, just not locking in to the groove in a satisfying way. Was starting to despair at my timing - figured I just needed more metronome practice - but then I de-activated the “adjust for record latency” box, and the next take, when played back, seemed to lock in to the groove exactly as intended!
What confused me at first was, if did the latency test where you record a click back into cubase (to check if the recorded file lines up with the output one) it makes no difference whether this box is checked or not, or if any plugins were active on the channels used.
Here’s what I’m guessing is going on: with “adjust for record latency” checked, cubase calculates the latency of what I’m hearing thru the amplitube plugin (which must be a couple of ms at least on full quality settings?) and moves the audio slightly to compensate for this. However, I think I’m timing my notes physically - i.e. matching pick hitting string with the click, as opposed to timing the presumably-slightly-delayed-guitar-signal-I’m-hearing-back-thru-the-monitors with the click. So, whatever the latency caused by monitoring thru Amplitube, I’m ignoring this, but cubase isn’t - hence it’s moving my takes slightly off from where I intended. To put it another way - though I’m monitoring thru cubase (and the Amplitube 4 plugin inserted on the channel I’m recording on), I’m playing (timing-wise) as if monitoring directly - however, with this box ticked, cubase is adjusting the audio as if I had compensated in my playing/timing for whatever latency Amplitube 4 has. I’m struggling to describe it any more clearly than this, so hope this makes sense!
Now it can’t be adjusting by very much - I am surprised that it’s enough to ruin the feel of a take, but I currently have no other explanation.
Could anyone confirm I’ve understood properly what the “adjust for record latency” box does? And does it sound plausible that whatever small adjustment it makes is just enough to make the timing sound slightly off in the recorded audio?
(btw, I don’t use direct monitoring as it’s hard to play guitar parts clean and get the tone you want - I need to hear how the virtual amp is responding to picking strength etc. - however I’ve got the asio buffer size as low as possible for recording, system latency about 4ms, hence tolerable.)
