#18 ardour hangs forever as soon as i try to add a drumkv1 instance

[matthieu imbert]

Hello and happy new year,

Ardour hangs forever as soon as i try to add a drumkv1 plugin or as soon as I try to load a session containing a dumkv1 plugin

There is nothing on ardour stdout/stderr

I use both ardour and drumkv1 from debian testing:

• drumkv1 version 1.2.0 (debian package version: 1.2.0-1)
• ardour version 8.10 (debian package version: 1:8.10.0+ds-1)

best regards,
Matthieu

by the way, where is the right place to submit ticket, here or github or somewhere else?

please try with the drumkv1-lv2 from the repos, either from OBS Debian 12 or the "Applications (noble)" PPA , as they are more suited to run on ardour due to qt6 being statically linked and self-contained.

A few updates:

• I struggled installing the debian 12 packages from OBS, and gave up. Instead I reverted to previous package versions from debian (debian packages 1.1.0 from snapshots.debian and 0.9.29-1 from debian stable) and in both case ardour hangs in the same way
• I was wrong when i said there is nothing on ardour's stdout/err. Here are the messages when I try to add drumkv1-lv2 plugin:

• I tried drumkv1 lv2 in Carla, and it works well
• I tried padthv1 lv2 in adrour and ardour hangs in the same way

So I suspect that maybe the issue is more related to ardour (but still, i would like to solve it!)

also i submitted a bug to debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1092795
