Kubbe

A reverb in three modes. $9, out October 1 · VST3 and AU on macOS (Apple Silicon and Intel) · VST3 on Windows.

“Kubbe” is Turkish for dome. Instead of the usual list of algorithms, Kubbe has three modes, each an algorithmic reverb inspired by a kind of space, on the face of a 1979 rack unit as it looked the day it left the factory. Nothing in it is recorded or measured from a real place: there are no impulse responses.

Modes

Hammam

Inspired by a marble dome. Dense, bright first reflections, a flutter between parallel walls, a ring in the low mids.

Cistern

Inspired by an underground cistern. The column slaps arrive late and sparse, and the tail is long, dark and moves slowly like water.

Valley

Inspired by open air. The far slopes answer one by one, each answer darker and more blurred. With Echo Sync they land on the beat grid.

Measured, not nominal

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.

The controls

Mix — Dry to wet.
Decay — Shown in measured seconds.
Pre-delay — In milliseconds, or synced from 1/64 to 1/4.
Distance — Near puts the early reflections up front; far is the room, darker.
Low Cut · High Cut — Shape the wet signal only.
Width — Stereo spread of the tail.
Duck — The tail steps back while the source plays, by up to 24 dB. It ducks, it does not mute.
Freeze — Holds the tail while you keep playing.
Echo Sync — Valley only: the echoes land on 3/4, 5/4, 7/4, 5/2 or 7/2 beats.

Price and licence

$9, or $15 for both plugins. There is no demo or trial version. A licence comes from a purchase or from a launch code. Without one, the plugin shows an activation card and passes audio through untouched.
