Instantly closes audio programs when adding
Linux Debian based distro GTK based Desktop Environment Ardour 8.6 Carla 2.5.5
I recently came across this plugin, have never used it before but it looks nice. I tried opening this up in Carla as well as in Ardour and in both applications I noticed that the second I try inserting this plugin they instantly close.
I was wondering if anyone else has experienced this before?
I tried both of the following plugin versions, I am not sure what the V3 Ratatouille.lv2-v0.8-linux-x86_64 Ratatouille.lv2-v3-v0.8-linux-x86_64
Thank You
I can confirm this issue.
Using Opensuse Leap 15.6 with an old Intel Core i5 CPU 750 here. Carla as well as Ardour crash when loading either version (binary; x86_64 OR V3).
In my console it says: "Ungültiger Maschinenbefehl (Speicherabzug geschrieben)" [= Invalid machine command (memory dump written) ]
This happens with all releases since 0.4, release 0.3 is the last that runs fine.
Probably the cpu optimizations introduced are the culprit.
Yes, that is a issue with the optimisation flags. Could you please post the output from
cat /proc/cpuinfo
Here the output of the first core, others have same feature set anyway.

So your CPU should be good for x86-64-v2 level optimisation (not v3). I've implemented some better checks for optimisation levels in the makefile, could you try to build from the latest git
git clone https://github.com/brummer10//Ratatouille.lv2.git
cd Ratatouille.lv2
git submodule update --init --recursive
make
make install
if that still don't work (let me know please), you could switch off all optimisations by using
make SSE_CFLAGS="" FFT_FLAG=""
Hallo Hermann
after struggling with fixing dependencies and OpenSuSE's old g++ version I come to this error:
Ratatouille.cpp:23:10: fatal error: lv2/core/lv2.h: Datei oder Verzeichnis nicht gefunden
Can't you provide me with a binary? I'm in a time-crunch lately
Yep, I've just pushed a new version (v0.9.1) out, here is the one without any optimisation flags applied https://github.com/brummer10/Ratatouille.lv2/releases/download/v0.9.1/Ratatouille.lv2-v0.9.1-linux-arm64.tar.xz
Ratatouille.cpp:23:10: fatal error: lv2/core/lv2.h: Datei oder Verzeichnis nicht gefunden
you need the lv2-devel package.
Yes, right, LV2. I thought it was automatically loaded as subpackage.
OK, the binary works here, though with some side-effects. It doesn't crash anymore.
When I first started it in Carla or Ardour, it wouldn't load neither NAM-files nor IRs. Then after restarting both applications, it suddenly worked ??
In the file selection dialog i can't find directories set up as symbolic link. I use this as a shortcut, so i don't have to go through the directories (direct entry of the path to my NAM-folders not possible). The symbolic links don't show up anymore.
Yes, symlinks didn't work in the browser.
The browser supports the XDG user dir specifications, that mean you could add a "Place" in your
~/.config/user-dirs.dirs file (If you don't have this file, simply create it) by just add a new line like this:
XDG_NAM_DIR="/path/to/NAM/"
That will add a place "NAM" to the left side Places in the browser. You could do the same for aida-x files, IR files, . . .
Alright. I got the compile to run through now.
The symlinks used to work in version 0.3.
Thanks for the user-dirs tip, this is a good work-around for me. The only thing I find annoying is, that in the files dialog all paths are displayed as full path. But that should probably go into another issue, right?
So for me the original issue here is fixed and can be closed.
Should I open a new issue for the symlinks?
yes, please open a new issue for that so I can't forget it. It may take some time before I could look into it.
OK, habe ein neues Issue dafür eröffnet.
Hermann, vielen Dank für die schnelle Hilfe und den Fix. Und deine hervorragenden Leistungen rund um Open-Source Amp-Simulation. Danke !
Hier zwei Tipps, die evtl. interessant fü dich sein könnten:
- Physik der Elektrogitarre, inkl. fundierter Info zu Röhrensound vs. Transistor
- Tweed Deluxe Emulation JSFX, inkl. detailliertes Paper zur Umsetzung/Verfahren
@DevFreeTwo Danke. Dein Hinweis das symlinks in version 0.3 noch funktioniert haben half mir den Fehler schnell zu beheben. Danke für die Links, die tweed Deluxe simulation ist sehr interessant, ist das von dir?
@brummer10 Gerne geschehen.
Der Tweed Deluxe ist nicht von mir. Bin eher durch Zufall über das GITEC Forum darauf gestoßen. Das ist ein Verein, der sich der Förderung der wissenschaftlichen Erforschung der E-Gitarren Technik widmet. Also kurz, die Fakten beleuchten, statt dem Marketing.
Auf deren Website gibt es allerhand interessantes zu erfahren. Auch zu Modellierung oder DSP Programmierung. Der ebenfalls verlinkte Youtube-Kanal hat auch etwas mit dem Verein zu tun.
Helmut Keller freut sich bestimmt über Feedback..
