This is a great interface, but it may be a bit challenging initially to set up correctly for your application. Be patient! I highly recommend using a computer and the iconfig software to set it up and to make changes. If using an iPad, the included lightning to usb-B cable is essential, but a bit short. Do not try to extend this cable. Bad things will happen. I use this with a PC, an iPad, 2 usb keyboards, and a 5 pin DIN midi keyboard, all simultaneously in a live band situation.
