Dual engine architecture
Engine A and Engine B each switch between Delay, Comb and Granular, making parallel, serial and hybrid textures easy to set up.
Phantomexposure audio software
Dual-engine comb delay and granular texture processor.
CombGrain combines delay memory, comb resonance, granular smear, routed dual-engine interaction, Phasefield movement and a compact character Space section.

Core idea
A hybrid environment, not a single-purpose delay.
CombGrain is built around two engines that can each run as Delay, Comb or Granular. The engines can behave independently, interact directly, feed one another, cross-channel ping-pong, or act as a send/return texture layer.
Its character comes from how those blocks push into each other: Delay gives memory, Comb gives pitch and resonance, Granular gives texture, Phasefield gives motion, and Space gives environment.
Routing as sound design
Coupled, Decoupled, Series, Ping-Pong and Send/Return modes change the relationship between the two processors.
Phasefield motion
Attract, Orbit and Shatter pull the engines together, circulate them or break them into unstable fragments.
Mode-aware modulation
The fixed matrix stays readable, but destinations change meaning depending on whether the engine is in Delay, Comb or Granular mode.
Space section
Room, Hall, Cathedral and Spring add character, with Size, Pre-delay, Scatter, Duck, Mix and Tone controls.
Wet-only and LIMIT
100% Wet can be fully wet with no dry layer, while LIMIT catches hotter experimental settings.

Useful sound directions
Resonance, dust, motion and spatial bloom.
- Metal comb shimmer — use two Comb engines in Series with Hall or Cathedral Space and slow TIME movement.
- Granular halo cloud — use Granular with Orbit, Position, Density, Stereo and moderated Scatter/Duck.
- Broken spring texture — send Granular into Comb or Delay into Spring, then try negative feedback.
- Resonant room pulse — combine Comb and Delay, Coupled or Ping-Pong routing, and slow LFO movement.
