Thanks for the reminder - I do forget that and get lazy and often use
the rt all the time.

Mostly audio/jack ie duplex 32 channels at 48k with a B* X32 mixer. To

But the truth is that use takes a very small part of my time and
normally a different machine so really I should use the rt kernel less!
