looks cool
By the way, have you thought about implementing a non-convolver reverb?

Sadly but not currently. There is a bunch of things to do before we can start working on a reverb plugin.

well, at least it’s good to hear that you plan on doing it at some point, because free software needs more reverbs :~)

hi @SadKo

a Manjaro user found a minor glitch with v1.1.14 plugin - spectrum_analyzer_x1

plugin still works no problem but with error message:

error: /usr/lib/lv2/lsp-plugins.lv2/spectrum_analyzer_x1.ttl:278:2: missing ';' or '.'
WARNING - Broken plugin parameter 'Channel': min >= max - pulseeffects 4.7.2-1 kills audio and locks PC after updates

i tried to use the feedback form on website but it does not appear to be working

many thanks for making some excellent audio tools

1.1.15 was released 3 days ago

Maybe the glitch is already fixed

Sorry for a bit late reply.
Yes, there was an issue of generating LV2 TTL files for some plugins which caused your problem.
Release 1.1.15 has fixed it.
