Geometry Reverb

Hall is the original, default algorithm: a smooth, spacious hall with a dense late tail. Start here for sustained synths, pads, and long washes. The original Hall sound is unchanged by the addition of the other modes.

Random is an irregular, chamber-like space with more prominent individual reflections and less emphasis on a smooth late wash. Its reflection pattern is controlled by the geometry, not by free-running random changes. Room Size stretches the reflection spacing and late-network timings; walls, height, angles, and node position reshape the paths and their balance.

Nonlinear builds a finite cloud of reflections instead of a continuously recirculating tail. It can swell and then end in a gated-like shape rather than fading like a conventional hall. It works on sustained sounds as well as short hits; there is no input-triggered gate to open.

Nonlinear controls use Tail Length to set the cloud's duration, Bloom to push it toward a slower, more pronounced buildup, and Decay to soften or tighten its ending. Reflections changes the density, Damping controls brightness, and geometry still shapes the reflection timing and stereo balance.

Moving between spaces choose one mode, then store contrasting sizes, shapes, and positions in the slots. Use Slew and the sequencer to move through them, or orbit the node continuously. In Random, try a small room in one slot and a much larger room in another to hear the reflection pattern expand as it moves.

Switching modes briefly fades the wet signal down, clears the previous reverb, and fades the new mode in. It does not morph or carry the old tail into the new algorithm. Use slot and geometry changes for continuous movement within a mode.

Input Gain sets the level entering the reverb. The center position is unity gain.

Decay sets feedback and the overall persistence of Hall and Random, with internal protection against unstable buildup. In Nonlinear it controls the softness of the cloud's ending.

Tail Length extends or contracts the late reverb independently of Decay, or sets the reflection-cloud duration in Nonlinear. Small feedback-based rooms automatically apply extra protection at long settings.

Reflections controls the strength and density of the surface-derived reflections feeding the reverb.

Damping removes high-frequency energy as sound circulates. Higher values create a darker and more controlled tail.

Bloom shapes the buildup and balance of the late field behind the early reflections. In Nonlinear it shapes the cloud's rise, with higher settings creating a more pronounced swell.

Width sets the stereo spread of the wet signal.

Duck reduces the wet signal while new input is present, then lets the reverb rise as the input falls.

Dry/Wet crossfades between the original input and the complete reverb output.

Output Gain sets the final plug-in level. The center position is unity gain.

Room Size sets the main time scale from a compact space to a broad hall. Smaller rooms receive stronger damping and feedback protection.

Walls morphs continuously from a three-sided room through as many as nine walls. Intermediate values fade a surface into the model instead of switching abruptly.

Height sets the distance between floor and ceiling and changes the vertical reflection paths.

Wall Angle leans the walls toward or away from the center, changing reflection distances and variation in the late network.

Ceiling Slope raises one side of the ceiling while lowering the other, changing the ceiling path as the node moves across the room.

Walls exchange energy with other walls, the floor, and the ceiling. The visualization shows the current control geometry and active paths.

Position X moves the node left and right and changes horizontal reflection timing and stereo balance.

Position Y moves the node vertically between floor and ceiling.

Position Z moves the node through room depth, bringing one set of surfaces closer while moving away from others.

Radius sets orbit size. Small values create subtle movement; larger values make the modulation more obvious.

Rate sets free-running speed and direction. The center position stops motion; opposite sides reverse the orbit.

Sync changes Rate to host-clock divisions. Orbit phase resets with transport only while Sync is active.

Ellipse stretches the orbit on one axis, passes through a circle at center, and stretches it on the other axis beyond center.

Rotate X / Y / Z rotate the path around the three room axes from -180 degrees through 0 at center to +180 degrees.

The node remains constrained inside the current room even when the intended orbit would cross a surface.

1-4 select a slot for editing. Changing a stored parameter automatically updates the active slot.

Copy / Paste copies or pastes the complete stored state of the active slot.

CLK OFF stops automatic stepping. Slots can still be selected manually.

CLK INT advances through enabled slots from the internal Rate in Hz.

CLK HOST advances from the DAW transport and changes Rate to musical divisions.

Rate sets internal speed or the host-clock division, depending on the clock mode.

Slew sets transition time with the clock off. In clocked modes it becomes a percentage of the current step.

Holding a parameter while sequencing writes only that parameter into every incoming slot. Unrelated parameters continue their own slew.

Random rewrites the active slot with new reverb, geometry, position, and orbit values.

Slew sets how long the random transition takes when the slot clock is off. In clocked modes it follows the current step length.

Reflection mode, global gain, mix, ducking, and Slew are excluded from randomization.

Geometry changes use the same smoothing as slot transitions, avoiding abrupt delay-time jumps while the room changes shape.

For subtle movement, keep Radius low and randomize related slots. For stronger transformations, combine larger room, node, and tail differences with a longer Slew.
