More Carbon Sync Issues...Must Get Solved...

[tomhartman]

So today I did two acoustic guitar tracks. Both were sent directly to the main mix out.

When I played back the first track (against a reference track), it was fine. Then I noticed I still had the DSP button engaged, so I turned it off. Now the first track was out of sync. In the edit window you could see the part came in exactly where it should have, on Bar Two, but I was HEARING the audio a good half second early.

What? This has happened before as mentioned in my previous threads on this. We sent a session to engineering at AVID and they came back with a reply about me routing things wrong, which turned out NOT to be true, as later that session worked fine after rebooting Carbon and the Mac.

After doing that today, the first acoustic guitar track played back fine.

Now I went to record a second guitar track, played back, and all was fine...UNTIL...I disengaged the DSP button. Once again, now the SECOND track is playing early.

Again, both guitars are assigned out the main mix outs, no plug ins on the master or the individual tracks.

I have lost more time dealing with this over the months that I don't know whether have a funky Carbon unit or what.

Where do I go from here? Am I misunderstanding something? Once in DSP mode, does the button have to stay engaged even on playback? If I turn it back on, playback is fine. But the first track has DSP button OFF and after restarting plays fine, so it can't be that.

Right now the only way to hear guitar 2 in sync is to keep the DSP button in on playback.

Thx
