Hello everyone. I've got extremly Basic question. I'm connecting my midi input in interface with keyboard midi output . Everything is clear, i play some notes so keyboard is sending midi information to interface and then daw. Next, i am connecting interface midi output to keyboard midi input. I do know that daw is sending some information to midi keyboard, but what kind of information? It's hard to say but i really don't get it. Does connection "interface midi output to keyboard midi input" is a must when we want controll daw with keyboard additional faders and play/ stop/ rewind button ( on keyboard)?
