The BIG problem is Yamaha (others too) are now LEAVING OFF the MIDI 5 pin out connection on the lower end keyboards. Instead they use the USB to host so you connect to a PC. What a PAIN. do they really ever ask customers how they use these things?

Now to hook up a NP12 or 32 or whatever you have to buy an expensive USB host device or have a PC in between the arranger and lower.

Probably saves them a dollar.
