[PlanetCCRMA] [PlanetCCRMANews] the Planet lands on Fedora 10

First off, Windows or a Mac will probably not perform better than a 
Linux machine.

Second, do you really *NEED* the NVidia drivers? Can you get by with the 
NV drivers? They do not accelerate anything, but they do work, and they 
don't cause any problem with the -rt kernel.

Third, which kernels have you tried? Right now, the "stable" solution 
seems to be Fedora 8, with the 2.6.24-series -rt kernel from CCRMA. 
Fedora 9 and 10, and the newer -rt kernels, have stability issues.

Fourth, I've never used the Tranzport, so you'll probably have to find 
information on that from the Ardour home page.

Lastly, you **CAN** use Jack without a -rt kernel, by turning off the -R 
option if you start from the command line, or un-checking the "realtime" 
box in the settings dialog in qjackctl. However, you will probably have 
to use very large latencies in order to get it to work without xruns.

Good luck. We're all pulling for you.

This has put me a couple of weeks behind schedule, and I just don't seem to have an answer.  I don't seem to have a problem when I don't use the realtime kernels.  But I see lots of xruns with jack. Which brings up another question.  Can I make some decent multitrack recordings WITHOUT using the realtime kernel (I"m using a Pentium D dual-core CPU running at roughly .2.8 gigahertz, 2 gig of RAM).   Or do I HAVE to have the realtime kernel.
