SECTION 4

REVERB

Reverb can be thought of as a great number of distinct echos, called reflections, that occur so fast that our ear hears them blurred together as one. In nature, different size spaces give distinctly different sounding reverbs, depending upon the size and shape of the space (called Reverb Density), and the texture of the surfaces that the reflections bounce off of (called Reverb Diffusion). The various parameters of the MIDIVERB III make it possible to simulate nearly any natural reverberant space that can be imagined, and a few artificial ones as well.

The programmable parameters are:

REVERB ALGORITHM

There are 20 different Reverb Algorithms, or Reverb versions, in the MIDIVERB III. Each algorithm has a different sound and simulates a different acoustic environment. See Figure 5.
