Not talking latency, Fran. You insert a compressor on a group, or a channel send, and that audio path becomes delayed (actually, ANY plug in adds delay, but compressors with look-ahead functions are some of the worst culprits), now, when mixed back with the original signal, there are phasing issues or even worse, audible delay...

Most TOTL DAW's compensate for plug-in delay at ANY point in the signal path. This feature, to be honest, is more needed by amateurs than professionals who are usually aware that this is going on (and can compensate manually), but it's a feature of just about all modern DAW's.

I was just concerned that I couldn't find this feature trumpeted (which you would think they would if implemented)...
