MiniVerb is a versatile stereo reverb found in many combination algorithms, but is equally useful on its
own because of its small size. The main control for this effect is the Room Type parameter. Room Type
changes the structure of the algorithm to simulate many carefully crafted room types and sizes. Spaces
characterized as booths, small rooms, chambers, halls and large spaces can be selected.

Each Room Type incorporates different diffusion, room size and reverb density settings. The Room Types
were designed to sound best when Diff Scale, Size Scale and Density are set to the default values of
1.00x .
If you want a reverb to sound perfect immediately, set the Diff Scale, Size Scale and Density parameters to
1.00x , pick a Room Type and you’ll be on the way to a great sounding reverb. But if you want to
experiment with new reverb fl avors, changing the scaling parameters away from 1.00x can cause a subtle
(or drastic!) coloring of the carefully crafted Room Types.
Diffusion characterizes how the reverb spreads the early re fl ection out in time. At very low settings of Diff
Scale, the early re fl ections start to sound quite discrete, and at higher settings the early re fl ections are
