Large latency when side chaining compressor

[Alex Banks]

Hi there.

I have a problem with latency induced when side chaining.  I'm on a fairly new project with low plug in count.

When I try to side chain one track form another I get a delay from when I press start to when the music starts, and a delay from when I press stop to when the music stops.  I have tried Logic stock compressors and 3rd party ones,  still the same.  The delay is quite large and affects changing plug in settings as well.

I have tried creating new channels and no difference.  

Thanks!

By this do you mean that if you change a plugin parameter during playback, there's a delay (similar to the other delays you're seeing) before the change takes effect?

Het scg,

Thats right,  the latency is there.

Thanks!

Often with latency compensation issues in Logic, tracks are out of time with each other. Are you having issues with track timing relative to other tracks? Or is everything in time with itself, and it's just that overall, things like playback start and stop are delayed?

[Alex Banks]

It's just the overall thing.  As soon as I add one side chain comp it produces this latency problem.  It's a big jump.  I've had 100+ tracks with large processor loads and get the same thing,  but not when I add 1 comp with side chain.

I don't have an immediate answer, but if the tracks are in time with each other, that at least seems like it might be less of a problem than timing issues within or between tracks. There's low-latency mode, but that's likely to disable important aspects of the project. You could also experiment with buffer size. (Maybe someone else can offer further suggestions.)

Thanks.  I've done a lot of variations with buffer size etc.  It's a real pain!

Solved. 

It had something to do with Izotope De-crackle 6.  Removing this plugin removed the latency problem.

Go figure!
