Reverb
The Reverb effect is used to add ambience to the sound. It features the
following controls:
predelay: the predelay dial enables you to delay the processed signal by
a given amount so as to achieve a more natural reverberation. Normally,
shorter predelay times are applied in the case of smaller room sizes
while longer predelay times are applied in the case of bigger room sizes.
The predelay time can be synched to the song tempo using the pop up
menu beneath the predelay dial. See Appendix C for a list of all sync
settings.
room: the room dial is used to set the size of the simulated room. The
room size varies from a small chamber up to a huge hall.
damp: the simulated room's wall materials can be adjusted with the
damp (Damping) control. This parameter ranges from practically loss-
free reflecting walls up to very absorbent walls. In practical terms, the
amount of damping determines the amount of higher frequencies that
are contained in the processed signal: The higher the damp setting, the
less higher frequencies are contained in the processed signal.
