Forget this bad example. I caught a severe cold and my head is a bunch of

Use that description:

Test scenario:
- 1 drum track with fluid synth
- 1 audio track with the recorded drum track, aligned to perfec sync
- LADSPA plugin with noticable latency, e.g. autotalent or 4 instances of 
multiband eq

fluid synth track without plugin
audio track without plugin
-> perfect sync

fluid track without plugin
audio track with plugin
-> perfect sync

fluid track with plugins
audio track with plugins
-> perfect sync

fluid track with plugins
audio track without plugin
-> latency between both tracks, drums not perfectly in sync

So it looks as if there's no delay for an audio instrument added when
latency on a synth module instrument is detected.
