Someone asked me this and i see posts about this all the time, so i made a video. How can you control multiple layers/instruments/libraries in ONE vst instance (in this case kontakt) from multiple tracks in bitwig (2.3). Besides showing how you can do this, i dont recommend it. It´s too much setup work, "maybe" its not a performance saver at all (i think bitwig handles multiple instances better) and you complicate your setup (what channel routes to which instance and which output etc). Always keep things simple and straight forward.
