Would be nice keeping some log about which hosts only supports VST2:
- Ableton Live
- ACID / Vegas (* announced VST3 support coming soon)
- Audacity
- AudioMulch
- Ardour (eg. Harrison Mixbus, Podium and forks of it…)
Bidule- Cantabile
- DeVinci Resolve
- Deckadance
- Goldwave
- LLMS
- MultiTrackStudio
- Native Instruments (Maschine for example)
- OpenMPT
- PreSonus Notion? (not sure)
Pyramix- Reason
- Psycle
- Renoise
- VinylLab (though it seems JUCE based so VST3 can/will? be added)
- Yamaha’s Vocaloid (though Yamaha is affiliated with Steinberg so I guess it will be resolved)
And that’s only based on VST in wikipedia
