Inverse The Inverse algorithm allows you to vary the slope of the initial portion of the
reverb envelope. The slope can decay, remain level, or rise over a variable time
interval. When the time interval is up, the reverberation cuts off abruptly. The
resulting effect is similar to a gate, but is not at all dependent on the level or
complexity of the input signal. Slopes are adjustable over a negative, even, or
positive slope. Positive slopes create inverse effects, while more even slopes
create gated effects. Negative slope values have rather natural reverb tails.
