I presume you are trying to use the STANDALONE with asio? No solution for that. I wonder if it will work if you use the VST DLL in a different ASIO host? https://www.hermannseib.com/english/savihost.htm This runs as an exe, so maybe you can get going. I'm using the VST DLL in reason 11, under my audiobox ASIO and it works ok. Maybe you could try another sequencer that supports ASIO ?
