Cool man!I configured the keyboard in FL Studio as a midi device and now I play directly on the keyboard
I also have small midi controller (Alesis V25) for some quick sound or melody test.
I don't know if it is common, but playing via midi controller in FL (or DAW generally) has some lag from time to time. Maybe it is about USB entry or processor speed, don't know.
Anyway, playing on hardware is more satisfying to me and I prefer it, especially when jamming with a friend.
