Exact neutral state
All transformation controls at zero preserve the source for predictable gain staging.

VST3 cinematic audio processor · v1.6.2
UMBRA
One PENUMBRA engine, ten musical macros.
A sound-transforming processor with exact dry behavior at zero, host-synchronized movement, saved presets, and a portable DSP path toward dedicated hardware.
Architecture
The system behind the surface.
The audio engine is separated from the JUCE wrapper and editor. Each macro adds an independent layer around the source, while Hold, preset recall, smoothing, and transport-aware movement remain synchronized with the host.

Engineering decisions.
One engine
The same portable DSP direction supports plug-in and embedded hardware work.
Host synchronization
Patterned movement follows the DAW transport and tempo.
Stateful interface
Ten macros, Hold, and preset recall use the same host-visible parameter state as the DSP.
