DISTRHO 3 band EQ - https://github.com/DISTRHO/DPF-Plugins
TAP has a couple EQs (dunno about GUI, don't have them installed) - https://github.com/tomszilagyi/tap-plugins
Steve Harris has a few EQs (no GUI) - http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html
@dried Thanks! I know about DISTRHO (forgot to list it), but should look at TAP - these were LADSPA IIRC, so no GUI. Maybe Invada had something?
@unfa there is a TAP LV2 port at https://github.com/moddevices/tap-lv2/
Maybe available in AUR, not sure..
Then extra eqs:
- caps (ladspa officially, lv2 port at https://github.com/moddevices/caps-lv2, maybe in AUR?)
- eqinox (from distrho-ports / juced-plugins)
- melmatch-eq https://github.com/brummer10/MelMatchEQ.lv2/
- kuiza (from artyfx)
airwindows might have some, not sure.
and there are a few mixer-like plugins around, they may have an integrated eq.
@falktx I've tried loading EQuinox yesterday, but it crashed Carla :D
I should try again.
Also - thanks for the TAP and CAPS suggestions, I should check them out!
