I was hoping to get a Yamaha p-125 to be used as a master keyboard. I wanted to use it with my PSR SX900 as I wanted to get a hammer action instead of that organ type keys. But the Yamaha p-125 doesn't have a midi out rather it has a USB type B port which is used as a host port. So, is there any way I can use it to control the SX900 ? Really need help. Moreover I saw some options like midi host hubs but these are not available in my country. Just I need a simple way to connect these two boards. Really need the help.
