OK here's a quick synopsis of the Dattorro "Expert Reverb" algo in the Ensoniq DP/Pro

Lo Cut frequency and gain parameters

Hi Cut frequency and gain parameters.

Pre Delay 0-100ms

6 series diffusors on each input.
6 left, 6 right, each adjustable from 0.00 to 23.0ms in 0.1ms increments.

Master Diffuser Size 0-100%
Diffusion amount scaler -100% to +100%




Reverb Tank

Master Reverb Size scaler 0-100%

Mid Decay: 0.00 (produces no output) to 1000s
Low Decay 0%-400%
Low-Mid Xover 3hz-20khz
HF Damping 3hz - 20khz

Density 0%-100% this controls diffusion within the reverb tank, so it's possible to create a "constant density" reverb by setting this parameter to 0%.

8 delays in the reverb tank each adjustable from 0.00ms - 200.0ms These delays are matrixed somehow and there is an "Expert Reverb 2" algo which has a different arrangement of these 8 delays.

4 modulation LFOs which modulate the delays in the reverb tank, each has a depth adjustment from 0.00ms to 200.0ms and a rate adjustment from 0.00hz to 1.760khz.


Quite a flexible algo.... Certainly called "Expert Reverb" for a good reason...
