Roland KR-11 Owner's Manual

To perform a factory reset on your Roland KR-11, turn off the piano, then press and hold the "Rec" and "Play" buttons simultaneously while turning the power back on. Release the buttons when "Fct" appears on the display.
First, ensure that the piano is properly connected to a power source and turned on. If the issue persists, try performing a factory reset. If the keys still don't work, there might be a hardware issue, and you'll need to contact a professional technician.
To connect your KR-11 to an external amplifier, use a standard 1/4-inch audio cable to connect the LINE OUT jack on the piano to the input jack on the amplifier. Adjust the volume levels on both devices as needed.
To adjust the touch sensitivity, press the "Functions" button, navigate to "Touch," and use the "+" or "-" buttons to select the desired sensitivity level (Light, Medium, or Heavy).
Routine maintenance for the KR-11 includes dusting the keys and exterior with a soft cloth, ensuring the power adapter and connections are secure, and occasionally checking for software updates on Roland's official website.
Check the headphone connection to ensure it is securely plugged into the headphone jack. If distortion continues, try using a different pair of headphones. Adjust the volume level on the piano to ensure it is not too high.
Press the "Rec" button, then select a track using the track buttons. Play your song on the keyboard, and press "Stop" after finishing. Press "Play" to listen to your recording.
Yes, you can use the KR-11 as a MIDI controller. Connect it to your computer using a MIDI-to-USB interface. Ensure your computer recognizes the device and configure your digital audio workstation (DAW) to receive MIDI input from the KR-11.
Ensure the piano is properly connected to a power source and the power switch is turned on. If the display remains off, try a different power outlet or adapter. If the issue persists, professional servicing might be required.
Press the "Tone" button to access the sound bank, then use the "+" or "-" buttons to scroll through the available instrument sounds. Select the desired sound by pressing "Enter" or simply start playing.
