Logic and Apogee Rosetta recorded delay

Hey All,

I have a problem that has reached epic proportions. It started about a month ago and has progressively gotten worse.

My recorded audio via an Apogee Rosetta 800 (via firewire) is getting to the computer late. On input I have no delay listening through the Apogee monitoring software but listening back to what's recorded on disc I have a large delay. It's not latency per se, I can see the input reaching Logic in time from the meters. Very odd. A restart of my computer and the Apogee has solved this in the past (a pain) but now it seems to be with me for good.

I'll call Apogee on Monday, but till then anybody have a similar problem?

Dual 2 gig G5, iBook G4, iBook G3, Logic 7.1.1, Apogee Rosetta 800, Mac OS X (10.4.4)

Is Logic's plugin delay compensation turned on? When you record, always make sure Delay Compensation is turned off to make sure everything will be sync.

Hey Thanks for the response..

I have it set to tracks and instruments (I guess the middle setting) as suggested by the Apple Doc. So I should turn it off completely?

Yes, you should. I usually record with delay compensation off and no plugins and then, when I begin to mix and adding plugins, I turn delay compensation on all the way. If you use plugins like AdLimiter or Linear Phase EQ, you can be really off sync when you record.

This might be true but how come I get this delay on a fresh Autoload as well? No plugs, no audio inst, nothing. Just the one test track I recorded.

Also, why would they mess with the actually timing of recorded sound? It seems like stealling from someone to feed another, not really a solution. One thing I could ALWAYS count on since Logic 4 was if I played it, it was recorded to disk in time as I played it. So tracks recorded in time depend on my plug/inst load? Wow.

Honestly who here doesn't find it troubling that if your in the final stages of a mix and realize you need to make one overdub you can't do it in time?

If you have this problem with a fresh Autoload with no plugins, your problem is probably elsewhere.

What happens with PDC is this: if you have a plugin that delays the track for 512 samples, Logic will delay every other track for 512 samples to make sure everything is perfectly in sync. Now, if you're recording, you're playing in sync with the audio played back but since you're hearing the tracks a little late, you're recording your new track a little late.

I agree with you, it's a mess to switch PDC on and off everytime we want to overdub something. Logic should automatically adjusts this. Guess it's time once again for Logic Feedback.

Good idea - I left feedback about this a while back. It seems easy - if any tracks are record enabled, then PDC off. If no tracks are enabled, PDC on. Of course, Logic will include a handful of preferences to muddy the waters, but it should be possible.

Switching PDC automatically is another solution but what I wanted to say is that Logic should be aware of the amount of PDC used when recording and automatically adjusts the recorded audio to be in sync.

Touché...recorded audio should be in SYNC. Jeeez. This is insane.
