  If the auto accompaniment on your Yamaha Musical Instrument isn't working correctly, ensure that all accompaniment tracks are turned on and set to appropriate volume levels. Also, verify that you're using fingerings recognized by the selected fingering mode and playing in the correct section of the keyboard for auto accompaniment. Check that the auto accompaniment split point is set correctly and that you're playing chords the PSR-330 can recognize.

  If not all simultaneously-played notes sound on your Yamaha Musical Instrument, you are probably exceeding the maximum polyphony. The PSR-330 can play up to 31 notes at the same time, including split, dual, auto-accompaniment, song, and multi pad notes. Notes exceeding this limit will not sound.

  If a cartridge style or song cannot be selected or doesn't play correctly on your Yamaha Musical Instrument, make sure an appropriate Yamaha Music Cartridge is properly plugged into the cartridge slot, or the cartridge contacts are dirty. Try re-inserting the cartridge. If that doesn't work, try wiping the cartridge connectors carefully with a soft, dry cloth.
