[LAU] ArdourVST - Latency Management

Hello List, I worked with a (jacklab) VST-capable Ardour version and some free VST - plugins today and created some kind of a mic- channel strip with a deesser, eq, compressor, reverb, etc. The problem is: When I bypass the whole strip voice and music are perfectly synchronized. but when I turn all the effects on I have a bad latency between the (effect-free) music and the (channel-stripped) voice. When I use like 50 ladspa eq's, limiter or whatever at the same time in the same channel the voice in on time, so I assume that LADSPA plugins are either producing no latency (which i cannot believe) or there is some kind of a latency management. Is there something I can do about it (except delaying the other channels which is basically not possible since the delay changes with the number of effects) my machine is based on openSuse 10.2/JAD1.0 and I build ardourVST, following this link: http://wiki.jacklab.net/index.php/Ardour_with_VST thanks in advance -- Regards, Sebastian Tschöpel.
