Yamaha Clavinova CVP-900 Owner's Manual page 165

Problem
• The sound is distorted or noisy.
• A strange "flanging" or "doubling" sound
occurs. Also, the sound is slightly different
each time the keys are played.
Possible Cause and Solution
• The volume may be turned up too high. Make sure all relevant volume settings
are appropriate.
• This may be caused by the effects. Try canceling all unnecessary effects,
especially distortion-type effects (page 123).
• Some filter resonance settings in the Custom Voice Creator display (page 91)
can result in distorted sound. Adjust these settings if necessary.
• Is the gain of the Low band set too high in the Master Equalizer display
(Mixing Console — page 125) ?
Both the Main and Layer parts are set to "ON," and both parts are set to play the
same voice. Set the Layer part to "OFF" (page 57) or change the voice for each
part (page 55).
