[Jack-Devel] Jack Problems

Thank you Holger

I will work through this, I see what you mean.

If I can just get jack to have repeatable problems, then I can work with 
it, but at the moment it all seems random.

Re Motu, it cuts my dependency on a specific OS and has a great web 
based mixer, while it is usb complaiant with linux, Heaven! That way at 
least I can cut my problems in half. I will still have the jack usb/midi 
problems, but at least I have a rock solid os independent mixer option. 
The 1818vsl is Do$e only and is a horrible flakey piece of software. 
Huge upgrade. At least Motu is Linux friendly compared to most of the 
other manufacturers, so I go that way.
