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 (
). (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?
