• কোন শব্দ নেই: Check the master volume level. Ensure headphones are not plugged in if you expect sound from the speakers.
• Bundled Computer Game Not Starting: If the EZ-250i is connected to the computer and the game won't start, the Yamaha USB MIDI driver may not be selected as the preferred MIDI Music Playback Device in Windows.
