Notes on USB MIDI Usage

When both MIDI jacks and the USB port are connected simultaneously, the USB port has priority.
When connecting a USB cable to the CP139 digital piano, first connect the USB cable and then turn the CP139
digital piano power on.
When connecting the CP139 digital piano to a computer via the USB port, there may be a short delay before
MIDI communications begin.
If the CP139 digital piano is connected to the computer via a USB hub and the USB communication becomes
unreliable/unstable, please connect the USB cable directly to the USB port of the computer.
Turning on/off the power of the CP139 digital piano while connected via USB, or disconnecting the USB cable
suddenly, may cause computer instability in the following situations:
If there are any further problems experienced with USB communication while the CP139 digital piano is connected,
please consult the documentation provided with your computer and double-check all connections and relevant operating
system settings.
