I’ve installed mod-pitchshifter from the KXStudio repositories in Debian (Sid/Unstable):
mod-pitchshifter:
Installed: 5:20191001.5
Candidate: 5:20191001.5
Version table:
*** 5:20191001.5 500
500 http://ppa.launchpad.net/kxstudio-debian/plugins/ubuntu bionic/main amd64 Packages
100 /var/lib/dpkg/status
It provides a few different plugins, which I can load in Carla, but not in Ardour. For instance, 2Voice give the following error:
URI: http://moddevices.com/plugins/mod-devel/2Voices
Bundle: file:///usr/lib/lv2/mod-2voices.lv2/
Unsupported required LV2 feature: 'http://lv2plug.in/ns/ext/buf-size#fixedBlockLength'.
Unsupported required LV2 feature: 'http://lv2plug.in/ns/ext/buf-size#powerOf2BlockLength'.
Any ideas if that can be fixed?
