NEVERMIND it doesn’t work so far only my original method; Scaler state isn’t saved inside of the wrapper

Multi-MIDI VST wrapper version 2.1 by soaria on maxforlive.com Download this and the companion device. You can’t hear audio from the inside of scaler 3 anymore in the wrapper but if all you want to do is route midi it works just fine. DAW Sync works!

I tried it in the past, but I found it so much cumbersome, that I preferred changing the DAW

Respectfully, telling people to change their whole DAW just for one workflow fix is a bit ridiculous. But if it works for you then all the best! 
Ridiculous?
And why, if you get rid of many other issues?
Many tools exist so people can improve their workflows, don’t you think so?
Just as many cars or photo-cameras exist

Thanks a lot!!! I just made the setup as you said… works like a charm!
This doesn’t work if you want DAW sync to be a thing. I should mention that in my original post. The wrapper integrates poorly with Ableton on that front. If you just click play in your DAW, Scaler 3 doesn’t play automatically with it if working with the insta composer 2 wrapper solution.
