Algorithms and Parameters

DUAL-INV

This algorithm includes a dual pitch shifter combined with the
Inverse reverb. The pitch shifter has two voices. Each voice has
independent controls for pitch, level, delay, pan, feedback and
cross-feedback. The pitch of each voice is adjustable up or
down over a 3 octave range with a resolution of 1 cent.
Maximum delay time for each voice is 1.250 seconds.
Inverse reverb 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.
