[SOLVED] TrackFX_AddByName: JS effects can not be added after updating REAPER

[FeedTheCat]

After updating REAPER (to any version?) you can not add JS effects through API.

This returns -1:

reaper.TrackFX_AddByName(track, 'JS:Distortion', 0, -1)

until you open a "Add FX" window (which apparently triggers a JS effect re-scan?).

Tested on Linux.

Yeah since you need to build the database first (which is triggered by ADD FX")
Been like this forever.

Hmm, so what's the workaround? Running "View: Show FX browser window" twice?

[Sexan]

Maybe you can call EnumerateFX? maybe that will trigger rescan also

Thanks, that works!

Oh nice! Was just a hunch since my script does that on startup (in order to populate its internal FX BROWSER) and does not suffer from this issue

EDIT: But beware of very long fx list it will take a while... (I do caching after first run). I guess checking if jsfx.ini is populated in your case is the best solution here

You don't have to go through the whole list, this worked for me:

local fx = reaper.TrackFX_AddByName(track, name, is_input, instantiate)
if fx < 0 then
    reaper.EnumInstalledFX(0)
    fx = reaper.TrackFX_AddByName(track, name, is_input, instantiate)
end

I marked this thread as solved, but I guess it would still be nice if reaper.TrackFX_AddByName itself checked whether the database is built or not. (or better even if REAPER just rebuilds the JS database after updating). I've had this issue for months now but couldn't pinpoint what was causing it.

BTW EnumerateFX is V7 exclusive api

Two related things here:


1) the JS finding by filename is/was case-sensitive on Linux but not on other OSes. Changing this.
2) generating the JSFX name/filename translation cache is/was done on demand rather than at startup. Changing this too.

Great, thanks!

Can you please also add a feature to rename JSFX from FX browser like other plugin formats do? Primary for #hiding purpose because now there is no easy and fast way to temporarily hide some JSFX.
