plug-in slows down tracks?

I use Pro Tools LE with a 002R, on a dual 2.0Ghz G5 with 1.5 gigs of ram...

but i still get horrific latency when i use waves plugins on more than 1 or two tracks.

The latency only affects the tracks that have the plug-ins, but it throws absolutely everyting off

i was wondering what i need to upgrade to prevent this delay?

thanks very much
 
Well, latency is set before you even begin to apply plug-ins, so an effect plug-in wouldn't change your latency setting. If your CPU is bogged down, your CPU meter might spike, and you might have a drop-out, but your latency setting should stay the same. What do you mean by 'latency'?
 
If the plug-ins are being used in real time, there could certainly be latency problem depending on the application and the drivers that it's using.
 
it's called plugin delay.
every plugin you add to a track delays the track somewhat. as the audio passes through a plugin, it has to have time to process the audio...and while that track is processing your audio the other tracks without plugins are playing straight through, 'causing a delay in the sound on that track.

Pro Tools LE unfortunately does not have plugin compensation. It's one of the many things LE users have complained about for awhile. Your best bet is just to choose your plugins wisely or render them down as files once you get your settings that you like. Some of the waves plugins are very CPU intensive and may cause more delay than other program, so use them sparingly. In the mix windows down below the fader there is a little black box telling you what your volume for that track is....CTRL+click it a couple times until you see "DLY" and this will show you your plugin delay for that track in samples. You can either nudge that region back in time that many samples or add delays to the other tracks to help correct it.
 
Try not to use effect during tracking, otherwise you will have timing issues. In this scenario, you'll have to re-align the tracks manually.

However, if your tracks are already complete and lined-up, then adding an effect throws anything off...well...then something is terribly messed up or your sequencer sucks.
 
that did it

I think it's the plug-in delay that Benny is talking about. I tried nudging the tracks with the plugins back by the number of samples of delay, and that cleared the problem right up

thanks very much for all your replies.

Click to expand...

be careful when you do that though. you may want to time stamp each region before you move them. because down the road you may forget you moved them, and then forget how much you moved them by, and then all your regions are way off and you can't put them back in place....it can be confusing with a lot of regions.
 
cant you set up an Aux bus? i do that in tracktion a lot now...
 
Mix down the track and use the mixed down file.

I use Sonar 4, but when I was getting dropout from too many plugin's I'd "bounce" the track to another track to mix the effects into the sample. Not really sure if bouncing is a Sonar specific function though.

Maybe you could apply the same principle with a mix down of the track that has latency, then replace the original sample with the mixed down one.
