One more test: I added the autotalent-LADSPA module to all 5 slots of an unused audio track to make the delaying effect stronger. Tracks I recorded with my MIDI-Keyboard were deleyed by 1/8 note! So I guess rosegarden calculates somehow the maximum delay of each track and delays every other track in a way that they are in sync to eliminate different delays of different tracks. 1.) This doesn't work always. I remember shiftig vocal recordings a bit after inserting plugins. 2.) This should be compensated and applied as a negative shift for recorded tracks. I think it wouldn't be a bad idea to add a global setting "max. latency". If it's set to - say - 20 ms then every track's plugins are supposed to get things done in this time, summed up. If they need longer then something bad should happen (red light, distortion) so the user can set it to a higher value. Every recording should then be shifted back in time by this "max. latency" to get it in sync. Any facts or ideas? Maybe 1000 times discussed already?
