Page 31 - REVERB; REVERB ALGORITHM
SECTION 4 26 REVERB Reverb can be thought of as a great number of distinct echos, calledreflections, that occur so fast that our ear hears them blurred together asone. In nature, different size spaces give distinctly different soundingreverbs, depending upon the size and shape of the space (called R...

USING MIDIVERB III 27 REVERB DECAY The Reverb Decay determines the length of time that the Reverb willsound before it finally fades away. It is not used in the Reverse 1 and 2Algorithms. It is functional in all others. DELAY The Delay section of the MIDIVERB III can be used in two modes,depending up...
Page 33 - FIGURE 6
SECTION 4 28 There are 24 different Chorus Algorithms (Chorus versions), in theMIDIVERB III. Each algorithm has a different sound and simulates adifferent pitch based effect.There are two major types of algorithms: Chorus and Flanging (seeexplanation below). Both Chorus and Flanging have 6 algorithm...
