SECTION 4 26 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[...]

USING M IDIVERB III 27 REVERB DECAY The Reverb Decay determines the length of time that the Reverb will sound before it finally fades away. It is not used in the Reverse 1 and 2 Algorithms. It is functional in all others. DELAY The Delay section of the MIDIVERB III can be used in two modes, depending upon the configuration. In some configura tions,[...]

SECTION 4 28 There are 24 different Chorus Algorithms (Chorus versions), in the MIDIVERB III . Each algorithm has a different sound and simu lates a different pitch based effect. There are two major types of algorithms: Chorus and Flanging (see explanation below). Both Chorus and Flanging have 6 algo rithms of mono and 6 algorithms of stereo. See F[...]

USING M IDIVERB III 29 variables are available, from varying the Speed and Depth of the LFO to feeding back part of the signal to make the effect stronger. In the case of a Stereo Flange , the signal is split into three parts with a dry signal and a separate Delay section for both left and right channels with one channel flanging up while the other[...]

SECTION 4 30 INPUT EQ The INPUT EQ is a high-cut filter that rolls off the high frequency response of the input signal before it is sent to either the Delay, Reverb, or Chorus. The VALUE button selects the frequency where the signal has been rolled off -3dB. See Figure 7. EFFECT EQ The EFFECT EQ is a high-cut filter that is part of the currently se[...]
