Halo

A reverb built for the long end. Decays of twenty seconds and beyond stay readable instead of collapsing into a grey wash, and the freeze holds indefinitely without drifting.

Where the long decays come from

Drag size and decay and watch the tail. The faint line behind is the starting position, so you see the difference and not just the state.

How it works

Built for decays nobody else survives

The trick is not more diffusion, it is less. Halo thins the reflection density as the tail decays, so what remains stays open rather than piling up into noise.

Size5 to 200 metres of modelled space.
Decay0.2 to 60 seconds. Everything above 20 seconds is the point of the device.
FreezeHolds the current tail indefinitely with no drift and no build-up. Latching or momentary.
DampingSeparate high and low damping, both following the decay rather than a static filter.
WidthMono to wide, with a mono-below control for keeping low end centred.
CPURoughly 2.1 percent of one core on an M-series Mac at maximum decay.
RequiresAbleton Live 11 or 12 with Max for Live. Tested on macOS 13 and later and Windows 11.
DeliveryZIP containing the .amxd device, 24 presets and a PDF manual.
