Using Usb-Midi Directly To The Keyboard; Using A Usb Midi Adapter - Yamaha Tyros Series Manual

3.3 Using USB-MIDI directly to the keyboard

Keyboards with a USB to Host port can be connected using a USB printer cable. As the iPad
doesn't have a USB connection, you need an adapter (commonly called a camera connector)
to connect the iPad with the USB cable.

3.4 Using a USB MIDI adapter

Many USB to MIDI cables can be also used with the iPad. The cable is connected to the 5-pin
MIDI port (either midi A or midi B). Since the iPad doesn't have a USB connection, you need
a camera connector to connect the USB end of the cable to the iPad.
To avoid the adapter draining the iPad's battery, you can use an active USB Hub (with power
supply) between the iPad and USB MIDI adapter.
