Three rooms, each with its own voice. Pick one by ear. $9 · VST3 and AU on macOS (Apple Silicon and Intel) · VST3 on Windows.
Most reverbs hand you a list of algorithms and leave you scrolling. KUBBE gives you three rooms, and you hear the difference the moment you switch: a bright marble dome, a long dark cistern, an open valley whose echoes can land on your beat grid. Pick the one your track is asking for, set the decay, and get back to the song. It wears the face of a 1979 rack unit as it looked the day it left the factory, and every tail is made by the engine itself: no impulse responses, nothing recorded from a real place.
Short and bright. Dense first reflections, a flutter between parallel walls, a ring in the low mids.
Long and dark. Late, sparse early slaps and a long tail that moves slowly.
Open and rhythmic. Discrete echoes answer one by one, each answer darker and more blurred. With Echo Sync they land on the beat grid.
The decay display runs the engine on an impulse every time a setting changes. It draws the energy per 20 ms and the Schroeder curve, and prints the T60 it measures — at the default settings about 2.4 s in Hammam and about 6.6 s in Cistern. The Decay knob is scaled from that measurement.
Hammam is a marble dome: dense, bright first reflections, a flutter between parallel walls and a ring in the low mids. Cistern is underground: the column slaps arrive late and sparse, and the tail is long, dark and moves slowly, like water. Valley is open air: the far slopes answer one by one, each answer darker and more blurred, and with Echo Sync on the echoes land on the beat grid. Switching place lets the old tail ring out for 1.5 seconds instead of cutting it dead.
Duck steps the tail back while the source plays, by up to 24 dB, and Freeze holds it about 6 dB under its level while you keep playing. Pre-delay runs from 0 to 250 ms or syncs from 1/64 to 1/4, Distance moves from near to far and darkens the tail as it goes, Width runs from mono to 150 %, and the low and high cuts shape the wet signal only.
