FL Studio has a very useful feature: you can load the whole DAW as a VST plugin into another DAW. The implementation is done with a seemingly light VST bridge component that opens up the application.
The FL Studio approach takes care if audio rooting and the song tempo & position sync in a perfect way. Effectively the setup setup works as ReWire was intended to work when it was still a thing.
Please implement the similar VST wrapper for Renoise. I’m pretty sure that this would make the Renoise much more interesting software to many professional producers.
