What are Bluetooth MIDI and Bluetooth Audio?
Bluetooth MIDI transfers musical performance data wirelessly. Bluetooth Audio streams audio wirelessly to or from your piano.
Bluetooth MIDI is a wireless protocol that allows your piano to send and receive musical performance data — such as note on/off, velocity, and control changes — to apps and software on a connected device, without a physical cable.
Bluetooth Audio is a wireless protocol that allows your piano to receive audio from external devices (so you can stream music through its speakers) and in some models also send audio to wireless headphones or speakers.
