27.6 Reverb and Echo 
A click on FX in the View Options / Mixer Setup brings up the Output FX panel. Here all pa-
rameters for the effects Reverb and Echo are adjusted. 
Reverb. Activated by the On button. 
Type. Lists different reverb algorithms for selection. Available are: 
¾  Rooms 1 - 4. Algorithm for room simulation with different tonal 
colours. Room 1 and 2 sound dry and small, Room 3 and 4 brilliant 
and a bit bigger. 
¾  Envelope. Reverb effect in multitap technology, where the volume 
course (envelope) is freely adjustable. 
¾  Gated. Simpler version of the Envelope reverb for cut reverb 
effects. 
¾  Classic. Classic feedback-based reverb with comb filter, generating 
both the typical sound and the very long reverb times. 
General Settings 
PreDelay. Delay of the reverb signal. Adjustable from the current buffer 
size (some milliseconds) up to 999 ms. 
Low Cut. High-pass filter before the reverb generation, removes low 
frequency signals which should not cause a reverb sound. Adjustable 
from 20 Hz up to 500 Hz. 
Smooth. Softens the reverb effect, affects stereo width, density and 
sound colour. Adjustable from 0 up to 100. 
Width. Adjusts the stereo width of the reverb signal from 100 (stereo) to 
0 (mono). 
Volume. Adjusts the level of the reverb effects signal sent to the FX 
return bus. 
Special Settings for Room 1-4 
High Cut. Low-pass filter after the reverb generation. A reduction of the treble often lets the 
reverb sound more natural. Adjustable from 5 kHz up to 20 kHz. 
Room Scale. Determines the size of the room, thus changing density and length of the reverb 
effect. Adjustable from 0.5 up to 2.0.
