I have a digital piano (Yamaha DGX640) and I have BIAB software on my laptop. Other than enabling BIAB-generated sounds to play thru the Yamaha keyboard's speakers, are there any other reasons for connecting the two via MIDI? Wouldn't it be just as good to play BIAB songs thru the laptop (with external speakers) and to just play along on the Keyboard independently?

I'm not trying to be difficult or a troll, but I'm not sure I see any other reason to connect the two (laptop and keyboard) except for playing BIAB sounds thru the keyboard. Perhaps I'm missing other reasons to connect the two?

Thanks!
