On Phil his laptop it works without problems (specifically when he 
raises his DSP latency a bit), so I think my patch is very CPU-intensive 
and my and your computer aren't fast enough...

I'll see if I can make my patch more efficient (but I'm not sure if I 
can still find significant solutions... I thought about this efficiency 
from the beginning on...)
