[PlanetCCRMA] Try to configure Qjackctl, may be bug, etc.

[Aznar Jocelyn]

Hi,

I'm almost new to this list, I subscribed some times ago but I
couldn't make at all
anything work and my knowledges weren't enough to do and to ask something
about it at that time. But now things have changed, I hope :)

So, first, a short description of what I'd like to do. I would like to
use my digital
piano, combine it to a software synthesizer, like ZynAddSubFx or WhySynth,
and hear the sound produced by the software in my computer. As far as I've been,
I could only produce sounds with the software synthesizer on my computer
but without using the digital piano.

About my computer :
Sound card : Juli@ http://www.esi-audio.com/products/julia/

The digital piano : yamaha P-60 :

I'm not sure about how to configure it, really not :( and reading the
doc didn't help
me much because of, probably, lack of knowledge in this field.

Linux Violette 2.6.27.12-170.2.5.fc10.x86_64 #1 SMP Wed Jan 21
01:33:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
but for music I use this kernel : 2.6.26.8-1.rt13.1.fc10.ccrma.x86_64.rt

I installed planetccrma-apps.x86_64 and planetccrma-core.x86_64 and
some other packages.

About the issue now. Well first, Qjackctl and jackdmp make my computer
almost freeze when I
start them, most of the time. And when trying to use QjackCTL, I can't
manage to have
my piano starting the sound of the software synthesizer. I did try a
lot of different setting
for QjackCTL, like this one : http://pastebin.com/m4f21ec62

If you have ideas about how to solve the problem, not having some
generating by the
combo Piano/synthesizer and QjackCTL/jackd freezing the computer, I
would be very
happy to read them.

Something strange is that the computer doesn't freeze actually, it is
very, very, and yes very
slow, maybe it could be a clue.

Hope you won't mind the English mistakes, I'm not a native speaker.
Jocelyn,
Who still hopes to play music with its computer.
