I've got some probleme with the CPU Load of ardour when I
use rakarrack (I do not know if this is a ardour,jackd or
rakarrack related issue).
My test scenario:
I route the output of a ardour track to the input of
rakarrack and I route the output of rakarrack to the ardour
Then I turn "FX on" in rakarrack.
When I play a song everything is OK. But when I stop the
transport the CPU load increases dramatically. The result is
that I get the message similar to:: "Ardour is too slow..".
And the jack connection is lost.
When I turn the FX off while playing the CPU load does NOT
increases, when the ardour transport stops.
Any help would be appreciated.
P.S.: Some system information:
Debian Lenny, ardour 2.6.1, rakarrack 0.2.0,
jackd 0.109.2 in relatime mode,
M-Audio Audiophile 24/96 sound card.
Please try the CVS version, I think this bug is solved in this version.
In order to compile in debian lenny ... do the following:
apt-get remove rakarrack ...
Install the following libraries:
Get the sources:
cvs -d:pserver:firstname.lastname@example.org:/cvsroot/rakarrack login
( when the prompt ask for password ... just press enter)
cvs -z3 -d:pserver:email@example.com:/cvsroot/rakarrack co -P rakarrack2
Then run autogen.sh configure make make install
many thanks for your help. I've installed the latest CVS version.
When I stop transport in ardour jackd dies after getting some
xruns with the error:
subgraph starting at rakarrack timed out (subgraph_wait_fd=14, status = 0, state = Running)
jackd watchdog: timeout - killing jackd
P.S. my jackd settings are:
/usr/bin/jackd -R -p128 -m -dalsa -dhw:0 -r48000 -p128 -n3
Ummh .... that's really bad thing .... I will check .... I think I need some luck to solve that ...
good luck from my side. Greetings for your famous application.
I hope you are able to fix, because I'ld like to use it for my recording sessions :-)
Well ..... update your CVS sources ... and try again :)
Here works now .... but I do it in a non elegant way .... probably I'm worst programmer in the world :)
But ... I only know small ways to do the things ... and I'm to old to start learning how to code.
I was check with a Drum Machine program ... I will check now with Ardour and hope they works too .... anyway ... they are some changes in some math functions ... I need to test if that changes the effects... but seems fine.
I've done some first quick tests and it seems to work now.
I'll do some more tests later and I'll let you know the result.
