GoldVerb reverb parameters in MainStage
GoldVerb provides the following reverb parameters.

GoldVerb reverb parameters
Initial Delay slider and field: Set the time between the original signal and the diffuse reverb tail. If you are trying to attain a natural-sounding, harmonic reverb, the transition between the early reflections and the reverb tail should be as smooth and seamless as possible. Set the Initial Delay parameter so that it is as long as possible, without a noticeable gap between the early reflections and the reverb tail.
Spread slider and field: Control the width of the reverb stereo image. At 0%, the effect generates a monaural reverb. At 200%, the stereo base is artificially expanded.
High Cut knob and field: Filter frequencies above the set value from the reverb signal. Uneven or absorbent surfaces—wallpaper, wood paneling, carpets, and so on, tend to reflect lower frequencies better than higher frequencies. The High Cut filter mimics this effect. If you set the High Cut filter to its maximum value, the reverb sounds like it is reflecting off stone or glass.
Density knob and field: Control the density of the diffuse reverb tail. Ordinarily you want the signal to be as dense as possible. In rare instances, however, a high Density value can color the sound, which you can fix by reducing the Density knob value. Conversely, if you select a Density value that is too low, the reverb tail sounds grainy.
Reverb Time knob and field: Set the time it takes for the reverb level to drop by 60 dB—often indicated as RT60. Most natural rooms have a reverb time somewhere in the range of 1 to 3 seconds. This time is reduced by absorbent surfaces, such as carpet and curtains, and soft or dense furnishings, such as sofas, armchairs, cupboards, and tables. Large empty halls or churches have reverb times of up to 8 seconds, with some cavernous or cathedral-like venues extending beyond that.
Diffusion slider and field (Extended Parameters area): Set the diffusion of the reverb tail. High Diffusion values represent a regular density, with few alterations in level, times, and panorama position over the course of the diffuse reverb signal. Low Diffusion values result in the reflection density becoming irregular and grainy. This also affects the stereo spectrum. As with Density, find the best balance for the signal.
