- `VST3_CATEGORIES`
- Should be one or more, separated by spaces, of the following: Fx, Instrument, Analyzer, Delay, Distortion, Drum, Dynamics, EQ, External, Filter, Generator, Mastering, Modulation, Mono, Network, NoOfflineProcess, OnlyOfflineProcess, OnlyRT, Pitch Shift, Restoration, Reverb, Sampler, Spatial, Stereo, Surround, Synth, Tools, Up-Downmix
The delimiter should be a semicolon, not a space right?
According to the function _juce_get_vst3_category_string
on the line 1445 in extras/Build/CMake/JUCEUtils.cmake
string(REGEX REPLACE ";" "|" result "${vst3_categories}")
When I separated with spaces, the category shown in hosts was like Fx | <One Long Concatenated String Category>
