Anyone out there successfully using the Ambix (0.2.8) LV2 plugins with
I am having problems loading any of the plugins into Ardour5. This
happens with both the Fedora ardour package and the demo install from
Ardour.org. The Ambix plugins do load, for example, in Qtractor, but not
Ardour shows them in the plugin manager, you can select one, "Add" it
and then when you do an insert it a panel pops up that says "the plugin
xxx could not be loaded". Looking at the log I see (for example):
[ERROR]: LV2: Failed to instantiate plugin
The directory looks like this:
ls -l /usr/lib64/lv2/ambix_converter_o1.lv2/
-rwxr-xr-x. 1 root root 5171056 Nov 29 20:43 ambix_converter_o1.so
-rw-r--r--. 1 root root 5504 Nov 29 19:50 ambix_converter_o1.ttl
-rw-r--r--. 1 root root 901 Nov 29 19:50 manifest.ttl
-rw-r--r--. 1 root root 378 Nov 29 19:50 presets.ttl
I built the plugins according to the build instructions, and nothing
weird is shappening there that I can see (the build uses a recent
lv2-devel package, etc). All the Ambix standalone applications that are
also built work just fine with jack.
Any help appreciated! (I have students that want to use them... :-)
At some point in the past this was working but I don't know how recently
this broke (I think this was fine in Fedora 24, it is broken in my tests
on both Fedora 28 and 29).
Thanks in advance!
