Public bug reported:
About my system:
It's a new KDE Slimbook with KDE neon pre-installed, which itself is based on
Ubuntu focal.
I used aptitude to install ardour, calf-plugins, and some other stuff I need to
do my audio work.
All installed packages are up-to-date, there are no pending updates.
List of relevant installed packages:
ii ardour 1:5.12.0-3ubuntu4 amd64 the digital audio workstation
ii calf-plugins 0.90.3-1build2 amd64 Calf Studio Gear ...
Steps to reproduce 1:
- Open a new/blank Ardour workspace
- Add the "Calf Limiter" plugin (LV2) to the Master bus
- Double-click on the plugin to see its GUI
- Try to raise the "Oversampling" value to 4 using the knob => crash
Steps to reproduce 2:
- Open an existing Ardour workspace where the Calf Limiter plugin is present
already having an Oversampling value of 4.
- In this case Ardour will crash right during the startup.
- Workaround:
- start Ardour with the '-B' option
- activate all plugins (except the Limiter, which also would lead to an
immediate crash)
- open the Limiter and turn "Oversampling" down to 1.
- then the Limiter plugin can be activated and everything works fine.
PS:
I noticed this bug after I was rsync'ing my audio workspaces from my PC (based
on Debian/buster) to the new laptop. All workspaces and plugins (whether Calf,
Guitarix, whatever) worked fine, except for my "mastering" workspace which is
using the Calf Limiter plugin.
