Vst 2.4 source

hello all.
some applications i use do not support vst 3 but only 2.4. where can i find the opensource git for this please?

See this post:

is the full sdk in there?

I don’t know for sure, I never downloaded the “full” SDK from Steinberg, I always relied on what JUCE provided.
FWIW, that’s all what was needed to build VST2 plug-ins with JUCE back then
