How to fix no sound when pressing keys on Casio Privia PX-870 Musical Instrument?
If no sound comes out when you press a key on your Casio Musical Instrument, first, increase the volume using the VOLUME controller. Then, make sure nothing is plugged into the PHONES/OUTPUT jacks. Finally, ensure that the Local control setting is turned on.
Why is the pitch off on my Casio Privia PX-870?
If the pitch of your Casio Digital Piano is off, you can try the following: * Set the transpose setting to “0”, or turn the power off and on again. * Adjust the tuning setting to 440.0 Hz, or power cycle the instrument. * Ensure the octave shift setting is set to 0. * Verify that the temperament setting is set to “0: Equal”, which is the standard modern tuning.
Why does my Casio Privia PX-870 take so long to turn on?
If your Casio Digital Piano takes a long time to start, it's because it performs a memory format operation that takes about 20 seconds. Please wait until this operation is complete. Avoid turning off the Digital Piano while transferring data with a computer.
Why can't I transfer data from my Casio Musical Instrument to my computer?
If you cannot transfer data after connecting your Casio Digital Piano to a computer: 1. Ensure the USB cable is properly connected to both the Digital Piano and the computer, and that your computer’s music software has the correct device selected. 2. Turn off the Digital Piano, exit the music software, then turn the Digital Piano back on before restarting the music software.
Why does the tone quality vary on my Casio Privia PX-870 keyboard?
This is normal for Casio Musical Instrument. The slight differences in tonal quality and volume between sample ranges is an unavoidable result of the digital sampling process.
Why do notes cut out when pressing buttons on my Casio Privia PX-870 Musical Instrument?
This happens when multiple parts are sounding simultaneously (layer, Duet Mode, built-in tune playback, recording, etc.). Pressing a button changes the effect setting built into the tone, which causes notes to cut out or effects to change slightly. This is normal behavior for Casio Musical Instrument.
