lv2vst w/ radium?

[autumncheney]

actually already posted this at linuxmusicians.com, but i figured i'll just copy it here too

downloaded the radium demo today and it looks like a really cool program, but it doesn't support lv2 as of now. it only supports linux vst

of course, lv2vst exists and i'm trying to use that, but whenever i scan for it it doesn't seem to load, it keeps timing out and i have to cllck "cancel", and then no lv2 plugins show up in the menu

is it even possible to use lv2vst with radium? or am i doing something wrong?

I haven't tried lv2vst, but Radium is using JUCE to host VST plugins, meaning that it's using a stable code base for hosting VST plugins. Same as Tracktion for instance. Have you tried using lv2vst with other VST hosts?

[autumncheney]

i would, but the host would also need to lack lv2 support to get a reliable result, and i don't know any linux vst hosts that don't also support lv2

of course, maybe i could try to find a setting to just turn off lv2 plugins and test it that way

i'll test this tommorow, i'm in bed atm

If you use Ardour, you can check under "Type" in the plugin manager whether it's a VST or LV2 plugin.
I've compiled the lv2vst plugin now, and I guess it works, but I haven't been able to make it find any lv2 plugins yet.

From the readme of lv2vst it says that it loads all lv2 plugins when the plugin instantiates. I guess you an lv2 plugin that doesn't work with the lv2vst wrapper. Have you tried using "whitelist" to load only one plugin?

[autumncheney]

whelp screw my sleep schedule lmao

i'll try using the whitelist (actually the readme has an example line for the x42 plugins). i'll test that

It's working for me now. I just had to set LV2_PATH to /usr/lib64/lv2. I have the example lv2 plugins working ("fifth" and so forth) and also zynaddsubfx.

[autumncheney]

really? i have my LV2_PATH set to /usr/lib/lv2 and it still isn't working

also tried adding fluida (https://github.com/brummer10/Fluida.lv2) to the whitelist and that isn't working

by any chance, did you get something like this whenever you scanned for plugins?

No, but I don't have that many lv2 plugins. 3 seconds is not that much, so just click "wait 20 seconds more".

Do you have eg-amp, eg-fifths, eg-metro, eg-midigate, or zynaddsubfx? If so, try to set the whitelist to only contain one of those. Those are working for me.
Here's my whitelist:
