<div><br></div>Hello everyone. I have been having some great fun with the low latencies using qjackctl, sooperlooper, audacity, a dunlop crybaby wah-wah pedal, and a seymour duncan tweakfuzz pedal. Anyways, my question is about jack and more specifically, jackdmp. I recently compiled and installed jackdmp from a subversion link provided on the official jack page. I read that the jackdmp installation 'replaces' files in the existing qjackctl and is made to operate better with multi-core CPUs. I use an Intel Quad Core @ 2.4GHz x 4 so this would be good for me. Is there a way I can make sure that I have installed this properly? <div><br></div><div>Fernando. I think saw that you were on the contributors list as making jackdmp compatible with fedora 13. That's what I put your name in the subject. :) Also, I was wondering if there was a site where people post the latencies they are able to achieve using jack. I think it would be interesting to see how people achieve very low-latencies and what those latencies are. <br><br>> From: planetccrma-request@ccrma.Stanford.EDU<br>> Subject: PlanetCCRMA Digest, Vol 30, Issue 13<br>> To: planetccrma@ccrma.Stanford.EDU<br>> Date: Sat, 14 Aug 2010 12:00:01 -0700<br>> <br>> Send PlanetCCRMA mailing list submissions to<br>> planetccrma@ccrma.stanford.edu<br>> <br>> To subscribe or unsubscribe via the World Wide Web, visit<br>> http://ccrma-mail.stanford.edu/mailman/listinfo/planetccrma<br>> or, via email, send a message with subject or body 'help' to<br>> planetccrma-request@ccrma.stanford.edu<br>> <br>> You can reach the person managing the list at<br>> planetccrma-owner@ccrma.stanford.edu<br>> <br>> When replying, please edit your Subject line so it is more specific<br>> than "Re: Contents of PlanetCCRMA digest..."<br>> <br>> <br>> Today's Topics:<br>> <br>> 1.
