Troubleshooting
If you hear no sound or a strange sound, first check the items described below and take appropriate action. You may be
able to solve the problem by resetting the instrument to the factory settings (
page 21). (Make sure to back up any important
data to an external device first.)
If the problem persists, consult your Yamaha dealer.
■ No sound comes from the speakers.
•Are all four Control sliders set to appropriate levels (other than zero or minimum)? (page 16)
• Has the Local Control switch been set to off?
If this is set to off, the internal tone generator will not sound.
• Have you turned on the power of the S90 ES and all connected external equipment?
• Have you made all the appropriate level settings—including the Master Volume on the S90 ES 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 you using an external MIDI controller and are the MIDI volume and/or MIDI expression settings too low?
• Is the S90 ES properly connected to related external equipment (e.g., amplifier or speaker) via audio cables?
•Are the effect and filter settings appropriate?
If you are using the filter, try changing the cutoff setting. Some cutoff settings may mute the sound entirely.
•Are the volume or level settings too low?
•Are the element switch, note limit, velocity limit parameters set appropriately?
• When the Performance/Multi produces no sound, has a Voice been assigned to each Part?
• When the Performance/Multi produces no sound, is the output setting of each Part set appropriately?
