Why doesn't the ACMP ON indicator appear on my Yamaha PSR-EW300 Musical Instrument?
If the ACMP ON indicator does not appear when the [ACMP ON/OFF] button is pressed on your Yamaha musical instrument, always press the [STYLE] button first when you are going to use any Style-related function. Also, the ACMP ON indicator does not appear when the Duo mode is on.
Why do some voices not sound on my Yamaha Musical Instrument?
If not all of the voices seem to sound, or the sound seems to be cut off on your Yamaha musical instrument, it could be because the instrument is polyphonic up to a maximum of 48 notes—including Dual voice, Split Voice, auto accompaniment, song, and Metronome. Notes exceeding this limit will not sound.
