My first realization with Pd Vanilla, based on Joahnnes Kepler "Harmonices Mundi" (1619). A simple video mounted to highlight the planets sound.

Thanks, that's what I'm looking for, for the time being. I confirm it perfectly works with Vanilla (on Windows).

@alexandros & @oid, in my file /etc/security/limits.conf there were no one of the two lines suggested. So I added them
@audio - rtprio 90 # maximum realtime priority
@audio - memlock unlimited # maximum locked-in-memory address space (KB)

and...
the warning on priority 6 disappeared!
Something magic should be happened
Thanks a lot

@oid unfortunately priority 6... still present after restart. As told, if I run from terminal "sudo puredata", no error/warning message. Can't understand, but I guess it's a problem of my Linux knowledge, not of Puredata

@alexandros: done, after adding myusrn to the audio group I get
$ grep audio /etc/group
audio29:pulse,myusrn

but priority 6 message is still present

Update.

Removed and reinstalled all the libraries in a new folder: everything seems to work!

Thanks to all, herafter some comments.

If I run PD as root, "sudo puredata", the message 'priority 6 scheduling failed; running at normal priority' disappears. By the way, even if I opend directly the patch, so with the above error message, everything related to audio seems OK. So that's good, even if not so clear to me what happen...

[envgen] issue
Does [envgen] work if you call it with its full name including library name, [ggee/envgen]? -> No, it is not recognized (dashed box, not continuos line, for the object appears in the canvas)
Do other objects from ggee work? -> No, same dashed box
Do any other externals work? -> not fully clear, for instance the object [counter] that should be part of cyclone works, other object tried not
Path are set in the correct way, and is not clear to me what to do to install library with Deken.

I'm getting lost, what disappoints me is that on Windows I got no issue, but I'm trying to switch to Linux...

Hi, this is my first post. Started a couple of months ago studying PD. I'm using it on a Windows desktop and now also on a Linux based laptop. I've installed release 0.52 on both OS, with some external libraries. The object [envgen] of ggee works perfectly under Windows. Nothing to do with LinuxMint. I've the error message
"priority 6 scheduling failed; running at normal priority envgen 200 140 1 0 ... couldn't create".
I've set the correct path in preference. The library is present but it seems PD cant't find envgen when run in Linux.
Any help? What I'm doing wrong?
Thanks a lot
