Appendix Troubleshooting No sound? Wrong sound? When a problem like this occurs, please check the following points before assuming that the product is faulty. Many problems can be solved by executing the Factory Set operation (page 19), after backing up your data to an USB flash memory device (page 57). If the problem persists, consult your Yamaha dealer. No Sound.  Is this instrument properly connected to related external equipment (e.g., amplifier, speaker, headphone) via audio cables? Since this instrument has no built-in speakers, you will need an external audio system or a set of stereo headphones to properly monitor it (page 17).  Is the power of this synthesizer and any external equipment connected to it turned on?  Have you made all the appropriate level settings-including the Master Volume on this instrument and the volume settings on any connected external equipment? If the Foot Controller is connected to the [FOOT CONTROLLER] jack, operate the Foot Controller and check the sound volume.  Check the Local Control parameter in the Utility mode. When this instrument is used by itself and this parameter is set to off, no sound is produced even if you play the keyboard. [UTILITY]  [F6] MIDI  [SF2] SWITCH  "LocalCtrl"  Check the Direct Monitor Switch parameter in the Utility mode. When this instrument is used by itself and this parameter is set to off, no sound is produced even if you play the keyboard. [UTILITY]  [F5] USB I/O  "DirectMonitorSw Part"  When the Performance/Song/Pattern produces no sound, is the "ArpPlyOnly" parameter of each Part turned on? When this parameter is turned on, the corresponding Part produces sound only via Arpeggio playback. [PERFORM]  [EDIT]  Number [1] - [4]  [F1] VOICE  [SF2] MODE  "ArpPlyOnly?"

If you are using the filter, try changing the cutoff frequency. Some cutoff settings may filter out all of the sound.
