Wallace Reverb

Plate / Room / Hall - FDN tunings (base delay scaling, Decay→RT60 range, tonal damping bias).

The reverb time, 100 ms – 20 s, read in ms (e.g. 1500 ms). Changing Type keeps the time. A session saved before 1.9.3 runs the old engine and shows the old Decay % knob instead, sounding exactly as it did.

Scales the delay-line lengths (space / density).

How much faster highs decay than lows.

Input-diffuser allpass amount (smooths the onset).

Per-line delay LFO depth - breaks up metallic ringing on sustained / tonal input.

0–250 ms delay line in front of the FDN.

The final mix (last reverb knob). out = dry·(1−mix) + wet·mix, then output gain + polarity. A new Wallace and every factory preset start at 100% (fully wet, for a send); saved sessions keep their own mix.

The curve has two views. MAG is the familiar magnitude response. PHASE swaps in a −180°..+180° grid on the same log-frequency axis and draws the wet EQ’s own summed phase response, including the low cut - drawn from the exact same coefficients as the audio, so what you see cannot drift from what you hear. Useful for seeing what a steep cut or a high-Q bell is doing to the tail’s phase.

Static + upward/downward dynamic EQ on the wet tail (identical to Denzel’s engine).

Per-band drive shapers Saturate / Drive / Bitcrush / Wavefolder, oversampled where needed. Since 1.9.3 the drive works on the sound going into the reverb, so the reverb’s damping softens what it adds (no fizz on the tail), and raising a band’s drive changes its character, not its level. Bitcrush runs from about 5 bits down to half a bit, so it is clearly audible from the middle of the knob.

Each dynamic band can key detection off an external sidechain input instead of its own energy. Standard use: duck the reverb tail from the dry source. Falls back to internal detection when nothing is routed.

A high-pass on the wet signal only, 0–500 Hz (fully left = Off), on the meter bridge. The knob is spaced by ear: a quarter of the way ≈ 45 Hz, half ≈ 150 Hz, three quarters ≈ 300 Hz.
