What to do if SYNCHRO/FILL-IN, ONE TOUCH PRESET, or SUSTAIN button does not work on Casio Synthesizer?

If the SYNCHRO/FILL-IN, ONE TOUCH PRESET, or SUSTAIN buttons aren't working on your Casio Synthesizer, it might be because the instrument is in Song Bank Mode or a demo tune is playing. To resolve this, press the TONE or RHYTHM button to exit Song Bank Mode, or stop the demo tune and then press the TONE or RHYTHM button.
