Steinberg ASIO/VST3/VSTGUI

VST3

Steinberg no longer licences (simpler) VST 2
Seemingly no need to sign their license agreement for GPLv3 open source VST3 plugins.
VST 3 Developer Portal

ASIO

Not open source from Steinberg;
ASIO plugin for OBS-Studio has an open source portaudio fork
My impression is that Steinberg supports building ASIO drivers,
but not communicating with those drivers.

Windows 11 considerations

• using Visual Studio 2022 Community
• added CMake and path to it
• added path to MSBuild.exe (VS/2022/Community/MSBuild/Current/Bin)
  and bash alias msbuild=MSBuild.exe
• C:\Program Files\Common Files\VST3\

Building VST3 using msys64 ucrt64.exe, from How to build VST3:

• created C:\Users\bleke\AppData\Local\Programs\Common\VST3\
• temporarily enable Developer Mode in Settings > System
  

Using MSYS2 ucrt64.exe:

$ cd /d/my/GitHub/
$ mkdir VST3
$ cd VST3
$ git clone --recursive https://github.com/steinbergmedia/vst3sdk.git
$ mkdir build
$ cd build
$ cmake.exe -G "Visual Studio 17 2022" -A x64 ../vst3sdk
$ cmake --build .
