developing LV2 plugins for REAPER

be1 · 11-26-2022, 11:48 AM

Hello,

Being using REAPER on Linux, I rewrote one of my LV2 plugins with UI from Gtk2 to pure X11 in the hope REAPER could display it, but, despite the plugin works well with jalv and Qtractor, REAPER doesn't show it. Instead, a blank black surface is shown (when activating UI).

Is there somewhere a documentation on REAPER support for LV2 under Linux, so that I can adapt my plugin for REAPER ?

FYI, the source code is browsable at: https://git.noise.rocks/ben/lv2-ben
It is a simple 2D binaural stereo spacializer plugin.

I would be very glad if someone could provide any help to adapt it for REAPER.
Any idea ?
Thanks

Can't provide you with help on what you ask, just a comment: I don't know if it is wise to rewrite for X11 as it is getting replaced by Wayland in many mainstream distros.

Maybe for GTK3? Reaper lists it as a dependency anyway.

Oh thanks, I'll give a try rewriting it with Gtk3 too.

May I recommend that you use GTK4 instead of GTK3 if you are determined to use GTK?

i'll take a look to see if I can figure out why (plain X11 should work!), thanks!

ah looks like there's a typo in the .ttl: it should be ui:idleInterface rather than ui:idle . Made that change and it works.

(should also put it an optionalFeature, technically)

Not recommended considering we use GDK and not GTK.
