packaging of swh-lv2 / announcement: update in swh-lv2

Hello CCRMA community!

First, thanks to everyone involved in providing this very nice

I saw that you do not package Steve Harris' LV2 plug-ins¹.
Is there any specific reason for this?

As a plug-in was added to his repository recently², it would be very
nice you would include Steve's LV2 plug-ins in CCRMA as well.



PS: As I am not on the list, it would be nice if you CC me explicitly.

Problems with Pure Data in CCRMA-Repo

Hi Fernando,
many thanks for the work.
Is there a place where I can file bug-requests?
Particularly after the latest update, when I open pd, it says:

opened 0 MIDI input device(s) and 0 MIDI output device(s).
/dev/dsp (read/write): No such file or directory
(now will try write-only...)
/dev/dsp (writeonly): No such file or directory
/dev/dsp (readonly): No such file or directory

Gem: can't load library
pdp: can't load library
audio I/O stuck... closing audio

I have Fedora 22 and use alsa. Even if I now play sounds, there is no
output in the speakers. The bar at the upper right shows that sound
should be played.

All the best

Re: problems with cpupower under ccrma kernels for Fedora

I have similar issue - my CPU always run underclocked and making latency while transferring to faster or slower mode.

Is there a solution for this someone?

No pure data in repo for Fedora 22

There is no package for pure data in the CCRMA-repository for Fedora 22.
Are there any plans to incorporate it? If so, when can I expect it?

Best regards

fedora 22... some packages

Hey hi all,

I release a first batch of packages for Fedora 22, very lightly tested 
but seems to work. I have not tried to build failed builds yet. The 
packages include a 4.0.4-rt1 based kernel. Everything is to be found in 
the usual repositories...



Some "important" stuff is missing (supercollider does not build, did not 
try to build pd-extended as rpmfusion for fc22 is still not available).

How to create a 4.0 rt kernel package?


I'm looking for advice on compiling a 4.0 rt kernel "the proper way",
i.e. to have an -rt package that is similar to the official PlanetCCRMA
packages. Perhaps just some pointers to information on how this is done
for planet ccrma. I know how to compile kernels from the bare source
(from kernel.org), but haven't yet compiled rt kernels into rpms.

Do you have any scripts you use to build the rt kernels?

The reason I have to do this is because I'm on a machine that has an
Intel Broadwell graphics unit that only works properly with 4.0+
kernels:( That's why I've upgraded to Fedora 22.

Would be enormously grateful for any hints,

If I remember correctly, however, the X32 has a fan, has it not?  That
would make recording quiet sounds tricky if it's in the same location.

[SPAM:###] hardware digital mixing console


Has anyone tried Behringer X32 USB ports with ALSA and Linux?.

Looks like having a console by itself can solve the issue of channels on
audio interfaces. Although, not sure how low is latency on this board.

Aside from the above, seems to me that the X32 has many options for
concert and studio situations. High on priorities are options for
recalling snapshots of console's states.

It might as well serve as a surface for Ardour (Jack).

As far as sound X32 brochure claims that this console uses MIDAS

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?

Invalid signature


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?
