I saw that you guys removed the VST2 interfaces from the latest VST3 SDK as you announced you would.
For legacy reasons/preservation it would be extremely unfortunate to not be able to get a hold of the VST2 interfaces anymore. It is also very obvious that the 10s of thousands (maybe way more) of VST2 plugins that have been written are not going to be ported to VST3.
So here is my suggestion: simply release the VST2 interfaces open source. I am not asking you to maintain them in any shape or form. simply post them on your github account for example, with a big disclaimer that this will not be maintained and is discontinued. But that way for people who have projects relying on them they can still be compiled “legally”.
