Yeah, sorry that I said there was no latency, I do know that every software needs to process. What I meant to say was that the latency while recording was so low in fx Pro Tools, that I don't hear it. That is not the case with PD.
You don't specify which type of PT, but Pro Tools HD has only 5 samples (not ms) of latency. The LE systems have very high latency compared to what Logic and other apps can do though.
I use both Pro Tools LE and M-powered. You probably right, I have never made a comparison. I really didn't meant the discussion to be about latency in pro tools or any other software besides PD (though spinoffs of couse also can be very interesting). It was just that Roman Haefeli asked whether Babsycos experienced a similar latency in other software, and thereby indirectly saying that it could simply be a hardware setup problem and that PD not nessecarily has more latency than other software.
In my experience (and don't claim to be that experienced at all) I've been troubled with the latency in PD and not in any other software. But I would be very pleased if I'm wrong in the underlying assumption here and that is just a question of the right hardware/software setup, to decrease the PD latency to the unhearable.
So Babsycos original question still goes unanswered (besides the really good advice about jack): can you decrease the latency with improving you hardware?
