Tracktion plugins (retromod, waverazor) crash in all my DAWs

Hi all,

Since yesterday, i'm unable to use tracktion plugins (Waverazor LE, Retromod Fat, Retromod 106) in Harrison, Ardour and Bitwig.
Here are the messages from the DAWs

Bitwig :

Code: Select all

Could not load plugin
Plugin host died: Could not read async reply: End of stream

My plugin hosting mode was on "By manufacturer", i was unable to load every project with Retromod inside, Bitwig was just stucked.
I changed plugin hosting mode to "Individually" and it capable to load everything but Tracktion plugins.

Ardour & Harrison :

Code: Select all

Erreur de segmentation (core dumped)

... And the DAW crashes immediately.

Every vst I use works very well, it's just plugins from Tracktion which are crashing.
I tried to reinstall Tracktion plugin, replace the .so file etc... but nothing seems to change.
I did no major update since some days. I'm on Ubuntu Studio 19.10

Does someone have an idea how to solve this problem?

Hi,

I did no major update since some days. I'm on Ubuntu Studio 19.10

Is there way to rollback before all this has been began?
And, actually something was updated?

Does someone have an idea how to solve this problem?

Run in gdb and strace. Not much ideas for now.

Tracktion developers sure will have some ideas on that. Even with open source stuff, developers are the first to contact about any issues. I recently had a problem with Audio Assault's Aural Verb (it didn't work at all, got instantly blacklisted by Mixbus with no explanation provided), they came up with a fix, and the upcoming update will include it as well. Panagement by Auburn Sounds had similar issues, they were resolved in a recent update. If the developer doesn't know about the problem, they can't simply fix it.

I don't know about retromod and waverazor, but I used to love some of the Tracktion stuff (especially the DelayStudio and Master Mix). The crashes started for me a couple years ago. I tried to check out Waveform last year, but it froze my machine entirely. I got no response from the developers after reaching out a couple times.

From time to time I check to see if there are any updates addressing Linux issues, but I get the impression there's nobody home. System requirements on their website still say "Tested on Ubuntu 15". Their Linux thread at KVR is mostly about crashing behaviors.

Maybe it's a very small team and Linux is at the bottom of their to-do list.

Seems to be true. They fixes Linux bugs, but there a bunch of common problems in Tracktion and I doubt that they will rush to discover plugin's crashes in 3rd party DAW in unsupported distro.

As I say it's worth to try isolate crashing place at first.

I'd like to contact the support team but I don't even find a mail... tried on FB & youtube, stills no answer actually
@kott my experience in gdb and strace is near from the absolute zero so i'll don't try, i don't even how to use this...
I think i'll try a timeshift to bring back my songs and go back to present.

I asked them if they ignore any bug reports or not. Let's see.

Worth to try, if you want to resolve the problem. Because It's doubtful that developers can reproduce your crash.
Install strace by apt-get install strace
Run your DAW in strace and redirect output to file: strace -f ardour 2>/tmp/ardour_out.txt (it will run more or less slowly than usual)
Load problem plugins. After crash upload this file /tmp/ardour_out.txt to some hosting for share.

Ok, i'll try this as soon as possible

Ok, I tried to strace this !

I noticed that problem doesn't affect only Tracktion plugins but every JUCE based plugin.

Here's a strace with ADLPlug :

Another one with Tracktion Retromod Fat :
https://framabin.org/p/?6629d7c7a0fba5c0#fmd70lfFdT7IRxoKLbtBR94cBpPbC6Ejt/b6DV2fHW8=

I don't know how to interpret this... I'm completely out, what I have to do ?

Hm, no crash information in logs, is it executed with -f flag to strace?
I can say that I see some strange behavior at my machine, and it's not clear for me yet. Some JUCE-plugins crashes in jack-hosts.
Do you run Bitwig with jack? Can you test plugins with alsa only?

Hey,
Strace was executed with the -f flag
I tried since weeks to run Bitwig with Alsa, but an error occured and i can't do it.

Code: Select all

ALSA: snd_pcm_hw_params: connection timed out


I can load Ardour with Alsa but I have the same crash when loading JUCE plugins...
Another thing : I can load ADLPlug without GUI but I can't load Tracktion plugins at all...
