Pro Tools placing sound EARLY??

[Zarabozo]

Hello,

Today I noticed the strangest thing: ProTools is placing a recording 5020 (yes, 5020) samples BEFORE it should!

Or, Am I missunderstanding something? Am I too tired today??

This is how I noticed it:

1) I started a new session, just to test a new mic I got yesterday.
2) I created 1 audio track (no plugins, no routings, nothing, directly from the Digi002 input to Monitors), 1 Master track and 1 click track.
3) I started singing (with headphones) while listening to the click).
4) When playing back the recording, I could hear that the click I was hearing in my headphones was bleeding into the microphone. I noticed the recorded click (I mean the click bleed from the headphones to the mic) was sounding BEFORE the real click!!

So, I inserted a time-adjuster in the audio track and started putting time until the recorded click until they sounded exactly at the same time. The result: 5020 samples.

I started playing with the I/O sample buffer. No resulting change with that. I'm using the low-latency-monitoring feature to record the track.

So, I don't get it. I noticed in the past delayed tracks, because of the plgings and so. But This is the first time I notice a track is actually sounding before it was supposed to sound.

Both tracks, the recorded one and the click one, are going straight to Monitors. No plugins.

Has anyone seen this before?

However, that's a fix on version 8. Anyone should be on Pro Tools 10 or later to also enjoy Automatic Delay Compensation, which makes recording in Pro Tools a completely different experience.
