Unfortunately its a case of the LADSPA effects not being as well written as
you'd hope, and they don't work particularly well on a real time system.

You may get better results if you go into qjackctl and boost your periods
per second, however you may still run into problems. You might also try
finding a comparable effect (some work better than others).

Unfortunately Ardour doesn't have a feature where you can quickly mix-down
your effects destructively to the wave file - however there is nothing
stopping you doing this in an outside recording program (I recommend Sweep).


Regards
Niko
