Illthy Springsspring, hall and ambient reverb with Freeze

VST3 modulein the NoAMP zipv0.10.0

Four reverbs in one box, no impulse responses: the drippy chirp of a spring, a full boinging spring tank, a clean hall, and Bloom, a huge ambient wash with five shimmer voices. The panel shows only the knobs the selected engine uses.

Always there

ControlWhat it does
EngineAllpass: the dispersive spring, the chirp and drip. FDN: a smooth room or hall. Tank: a dispersive spring tank where every lap is an upward chirp, the real boing. Bloom: the ambient shimmer tank.
GateGates what goes INTO the reverb, so tails still ring out. −80 dB reads Off and is a true bypass.
AmountEqual-power dry/wet (default 33%).
DecayTail length. In Bloom it spans about 1 s to 300 s (50% is about 6 s).

Per engine

EngineExtra controls
AllpassDispersion (how spread the chirp is) and Boing (how much your picking dynamics kick the spring).
TankDispersion, Boing, and Tone (brighter as it goes up).
FDNTone, Width, Density, Mod (slow motion in the tail) and Freeze.
BloomTone; Shimmer (how much of each pass comes back pitch-shifted); Mod (slow random motion); High Cut (1.5 to 16 kHz); Size (the tank from half to double length); Freeze; and the voice menu beside Engine: Glass (octave-up halo), Choir (octave plus fifth), Grotto (octave down, dark), Haze (near-unison thickener), Waves (octaves up and down with a slow breathe).

Freeze (FDN and Bloom) is an infinite, lossless hold of the tail. Play over it.

Tone is hidden on Allpass but its last setting still colours that engine.

On the NoAMP board

The SPRING card on the board offers Tank, FDN, Convolution (load any reverb IR) and Bloom, adds Pre-dly, Low Cut and Sustain, gives Bloom Swell and Duck, and its Freeze turns the held chord into an endless pad. See SPRING in the NoAMP manual.
