Setting The Dde (Dynamic Damper Effect); Returning Settings To Their Default Configuration (Reset All) - Yamaha GB1K Owner's Manual

Setting the DDE (Dynamic Damper Effect)

The DDE (Dynamic Damper Effect) recreates the subtle resonances that occur when you depress the damper
pedal on an acoustic piano. You can set the DDE to suit your preferences.
Operation
Turn the DDE off
Turn the DDE on (5 levels)
The DDE setting does not change when you turn the power off.
Note
Even when the DDE is turned off, the sound continues as if you had pressed the damper pedal, but without any
resonating effect.
