Troubleshooting
Troubleshooting
The following table provides troubleshooting hints and page references for some common problems. You may solve
your problem by executing the Factory Set (page 145) after backing up your data to an external storage device. If the
problem persists, then contact your Yamaha dealer or service center.
No Sound
 Is the S90 XS/S70 XS properly connected to related external equipment (e.g., amplifier,
speaker, headphone) via audio cables?
Since the S90 XS/S70 XS has no built-in speakers, You will need an external audio system or a set of stereo
headphones to properly monitor it.
 Is the power of this synthesizer and any external equipment connected to this
synthesizer turned on?
 Have you made all the appropriate level settings—including the Master Volume on this
synthesizer and the volume settings on any connected external equipment?
Is the Foot Controller pressed down (when it is connected to the FOOT CONTROLLER jack)?
 Are all four sliders set to appropriate levels (other than zero or minimum)?
 Is the Local Control set to OFF?
If this is set to off, the internal tone generator will not sound.

 Are the MIDI volume or MIDI expression settings too low when using the external
controller?
 Are the effect and filter settings appropriate?
If you are using the filter, try changing the cutoff frequency. Some cutoff settings may filter out all of the sound.
