      If your Casio Synthesizer doesn't produce sound when you press the keys, several factors could be at play. First, ensure that the VOLUME knob isn't set to MIN; adjust it towards MAX. Secondly, if headphones are connected, disconnect them. Also, verify that Local Control is turned on. Finally, check that the accompaniment mode is set to NORMAL.

      Benjamin FloresAug 6, 2025
      If you're not getting any sound from a connected external MIDI sound source when you press the keys on your Casio Synthesizer, there are a couple of things to check: 1. Make sure that the digital piano's Send Channel matches the Send Channel of the MIDI sound source. Change the Send Channel settings, so they are identical. 2. Verify that the volume or expression setting of the external sound source isn't set to 0. If it is, change it to an appropriate value.
