Ubuntu Studio & Qsampler

Wowzer.. So, quite the output from that command you gave me - Very.. err..

And here's the output qjackctl's Messages gives me when I try to run as
realtime:

Thanks a ton, Chris!

On a related topic, can anyone point me toward a good guide to understanding

realistic, and how to achieve it.

Thanks!
