I'm sure this has come up a few times, but...
I still do think that having and LV2 external for Pd (Linux) would be really useful for various reasons:
effects) on Linux
usable host is Carla [1] which does have a set of limitations especially for more 'dynamic' / 'creative' stuff.
frozen by now
somewhat more limited ecosystem on Linux [*]
programming and LV2 capabilities would be great and allow many interesting possibilities...
I see there is still this page: https://puredata.info/dev/summer-of-code/PluginHostLV2
where LV2 is cited as "the new emerging standard for audio plugins" (sic.)
[*] I'm wondering also if most of the Pd users' community is now on non-Linux platforms and therefore just happy to use VST therefore making something like LV2 (and by extension Linux) less relevant?
Just thought it would be interesting to re-open this discussion.
