Algorithm Control
This control selects one of seven reverb algorithms: Hall, Church, Plate, Room 1, Room 2, Ambience, or Non-linear. Selecting an algorithm changes the preset provided for it. Switching the Size setting changes characteristics of the algorithm that are not altered by adjusting the decay time and other user-adjustable controls. Each of the seven algorithms has a distinctly different character:
• Hall
A good general purpose concert hall with a natural character. It is useful over a large range of size and decay times and with a wide range of program material. Setting Decay to its maximum value will produce infinite reverberation.
• Church
A dense, diffuse space simulating a church or cathedral with a long decay time, high diffusion, and some pre-delay.
• Plate
Simulates the acoustic character of a metal plate-based reverb. This type of reverb typically has high initial diffusion and a relatively bright sound, making it particularly good for certain percussive signals and vocal processing. Plate reverb has the general effect of thickening the initial sound itself.
• Room 1
A medium-sized, natural, rich-sounding room that can be effectively varied in size between very small and large, with good results.
• Room 2
A smaller, brighter reverberant characteristic than Room 1, with a useful adjustment range that extends to “very small.”
• Ambient
A transparent response that is useful for adding a sense of space without adding a lot of depth or density. Extreme settings can create interesting results.
• Nonlinear
Produces a reverberation with a natural buildup and an abrupt cutoff similar to a gate. This unnatural decay characteristic is particularly useful on percussion, since it can add an aggressive characteristic to sounds with strong attacks.
