pd-extended

I tried using Pd a little on the current fc21 and I can't get pdextended to
load the defualt settings file. I understand that packaging pd is always
tricky but am wondering if I may be missing something. I noticed that
pdextended is just a link to pd binary (is this how it should be?). I am able
to add one of the extensions (freeverb~) and then load the object. Do I need
to manually add each library to the path?
thanks

Invalid signature

Hi,

I recently installed Fedora 21 on a new system. After installing the planetccrma core packages, attempting to boot the realtime kernel gives the following:

  error: /vmlinux-3.18.9-201.rt5.1.fc21.ccrma.x86_64+rt has invalid signature.
  error: you need to load the kernel first.

  Press any key to continue...

Has anyone else seen this, or know what causes it?

Thanks,
Len

JACK 1 vs 2

Hi Fernando and all,

I've been doing some light testing of an Ardour4 rc build in the last day or so, and I ran into some issues with JACK2 1.9.10 - the current version for Fedora 21, including:

  - Ardour UI locked up at the end of exporting; had to kill it.
  - After restarting, UI is "awake" but, eg, clicking on buttons doesn't have the intended effect; Session > Quit also didn't quit Ardour, so eventually had to kill that one too.
  - The second kill results in a run-away jackd process.

Other issues have been mentioned in Ardour-land as well, including the lack of an option (-T) that allows for Ardour to stop JACK itself, if it started JACK when the session was opened.  Apparently that's been added to a newer version of JACK2, but it doesn't seem to have been published yet -- even in Git, the latest tag is 1.9.10.

I built JACK1 0.124.1 - itself over a year old - from source, and ran qjackctl and Ardour with PATH and LD_LIBRARY_PATH augmented to pick up my JACK1 installation[1], and with that I haven't seen a single issue so far. As a (minor) bonus, qjackctl and Ardour now show 100% DSP load during export, whereas JACK2 typically showed 8-10%.  (This has been the case for some time, even with A3.)

So, just wondering whether others have seen any of these issues.  If so, might it make sense for CCRMA (or, Fedora?) to switch to JACK1 ?  Or are there dependencies on JACK2 functionality that would make that problematic?

Thanks,
Don

[1] - Note that this is not the recommended installation method.  In fact the JACK web site clearly states that > 1 JACK installation on a machine is a recipe for failure.  At the time I was in a hurry to test, and it worked for what I was doing at least.

Pure Data on Fedora 21 - can't connect with jack

Hallo,
I have several problems with pd on Fedora 21 64bit:
1. I can't install pd-extended-extra. YUM complains about missing 'mpg321'. There
is no such package in repository, so I compiled and installed mpg321
myself.It doesn't help. I also tried 'yum install --skip-broken'
but with no success.
2. I installed pd-extended but I can't connect it to jack properly. When
I choose Jack as my Audio Driver (the same options as my qjackctl
session - 44100 Hz, Block size: 512) jack throws these messages:

JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = pure_data_0 was not finished, state =
Triggered
JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = pure_data_0 was not finished, state =
Triggered
...
It continues without end. Pd window "Audio Settings" just freezes and I
can't change my settings. Other pd options works fine. 
How can I remedy these problems? 
Thanks in advance.
Best regards,
Piotr Komorowski

PS. I've used planetccrma for several years now (from fedora 12) and for
me it's the most stable linux audio workstation. Many thanks for yours
efforts!

Broken dependency with planetccrma-core on Fedora 21?

Hello,

When updating my system today I observed the following dependency issue:

Error: Package: planetccrma-core-2015.03.22-1.fc21.ccrma.x86_64 (planetcore)
           Requires: kernel-rt-3.18.9-201.rt5.1.fc21.ccrma

I removed the planetccrma-core package and updated again, and
kernel-rt-core was installed.  Maybe package renaming caused the issue?
 Is planetccrma-core not the recommended way to pull in dependencies
anymore?

In any event, I'm leaving planetccrma-core uninstalled for now.

Thanks,
Michael Wilson

another nvidia driver problem

hello,

I've tried following the instructions posted to this list about a year ago
(http://ccrma-mail.stanford.edu/pipermail/planetccrma/2014-April/018347.html)
to try and get nvidia graphics working. But after I install akmod and reboot I
can't login any longer. I had to move the nvidia config files (*) in order to
be able to login.
any idea how I track the problem and possibly get the driver working? 
Also in the process I lost the option of 1440x900 screen resolution so the
image is stretched. Any clues how I can restore that resolution option if
fixing the drivers doesn't work?
thanks

(*) mv /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
mkdir /etc/X11/nvidia-backup && mv /etc/X11/xorg.conf.d/*nvidia* 
/etc/X11/nvidia-backup

Re: external soundcard future

USB is fine as long as you don’t have to use 44.1 or 88.2 - USB soundcard frames are 1ms long, so if there’s a
non-integer number of samples per ms you get variable sized frames, which is… yuk!

i went to f20 because of the ccrma repo's. i noticed that the last (work in progress) was the version 20 so i
went for that...
also noticed that the pd-extended is buggy... doesnt load pdp or gem libs and doesnt respond to the quit
program command.
