JACK in F15
by William Blackburn
I am having trouble starting JACK in Fedora 15. I really want to try out some ladspa effects in JACK-rack. Can someone help me configure it properly?
Maybe someone can write a how-to? i'll write it if you tell me how to set it up. a short explanation should do me
thanks,

Fernando,
I usually try to get 5ms or less of latency with 41000 smaple rate and 64 frames/period and 2 periods/buffer.I do use JACK and I usually limit my self to use JACK as a guitar effects processor. I think it will also work fine with a recording app like qtractor as well. Actaully I was getting super low latency with the liunxDSP reverb effect. About 1.667ms believe it or not :) Here is a link to the patch and the kernel to patch against http://users.on.net/~ckolivas/kernel/. I think this is a better alternative b/c it does not require any c group privileges. Please feel free to try it and let me know what you thought. The maintainer of the patch can be found on OFTC at #ck. Btw I get freezes with the ccrma F14 kerenel-rt. Is this normal?
Cheers guys,
Bill

Looking to get involved
by William Blackburn
Hello, you guys have most likely seen me on this before when I was
asking questions about something. However, I have been using Fedora
for a while now and I would like begin to get involved with the music
community. I am looking to maybe learn how to package things or to do
anything that would help out. Basically, I want to be part of the
team.
I wrote a wiki in the past but it has since been obsoleted.
This is the link.
https://fedoraproject.org/wiki/User:Tertl3/real-time
What could I do to help out?
Thanks a lot everyone!

kernel I use for music production
by William Blackburn
Hello, I want to share something with the music community. I have been using the stock 2.6.38.4 kernel with the "ck" patch and have had nothing but great results with it. No X-runs or anything. If anyone is interested, feel free to ask me some questions about it. If you are on Fedora 15 it might be a good options since I don't think CCRMA has a rt-kernel for Fedora 15 yet. I can tell you how I went about installing the patched kernel if you need. The patch also is said to speed up basic responsiveness, but this subject is up for debate.
Cheers everyone,
Bill

What is the best GUI program for a guitar reverb effect. I really like the linuxDSP effect, but it is no longer free.

hello,
I have recently installed F15 Beta. I have forgotten the fix to get JACK working. I remember it was something about disabling the firewire driver. Can someone please send me the short command that fixes this issue. I searched for it, but no luck. Sorry to ask twice, but I forgot to write it down.
