Grain Discharge

Input Gain sets the level entering the detector and rolling grain buffer. Raising it makes quieter details excite the simulation more readily; extreme levels can produce intentionally harsh digital clicks and clipping inside dense grain combinations.

Mix moves from direct input to the grain output. At zero the plug-in uses a dry-only bypass and the simulation stops, so it is not merely an output crossfade at that endpoint.

Output Gain sets the final level after the direct and grain signals are combined and before output protection.

The recent-audio buffer, cavitation detection, grain rendering, and particle state all run in the audio processor; the sound does not depend on the interface being open.

Burst controls how readily and strongly the simulation forms cavitation events. Higher values increase transient sensitivity, lower the event threshold, and create more frequent, energetic ruptures.

Density controls how much grain activity each excitation can support. Higher values increase the number and weight of grains produced around an event, making the cloud fuller; Burst is primarily about event formation, while Density is about how populated those events become.

Friction inversely controls movement. Lower settings create more turbulence, timing variation, stereo motion, and particle drift; higher settings restrain the field.

Size shifts particle and grain scale. Larger grains tend to be louder, longer, and more broadly filtered; smaller grains tend to be shorter, more narrowly filtered, and more strongly affected by pitch modulation.

Speed sets the global simulation time scale. Lower values slow event formation, movement, and grain pacing; maximum runs the model at full speed.

Fade In lengthens grain attack and particle growth. Higher settings soften individual onsets and also darken recirculated tail energy, moving the result away from sharp sprays.

Linger extends the grain release by looping captured material with crossfades. It also increases delayed follow-up grains and particle lifetime, creating thicker, more reverb-like clouds without simply stretching one grain.

Tone moves particle generation vertically and changes grain filtering. Lower particles use lower band-pass centers and darker tone filtering; higher particles use higher centers and retain more upper-frequency content.

Pitch changes the probability assigned to three discrete pitch families for newly created grains. The control moves from base pitch toward a mixture of minor sevenths and octaves, ending with octave-up grains rather than gliding through intermediate notes.

Detune adds a random offset of up to plus or minus 100 cents to each new grain. It does not retune grains that are already playing.

Modulation sets random per-grain pitch modulation. Rates vary from roughly 2.5 to 15 Hz, and smaller grains receive more depth than larger grains.

White particles represent base-pitch grains, yellow particles represent minor-seventh grains, and red particles represent octave-up grains. Detune introduces only a slight hue shift.

Vertical position corresponds to a grain's band-pass center: lower particles are filtered lower and higher particles are filtered higher.

Particle size relates to grain amplitude, loop length, filter bandwidth, and modulation depth. A visual event can summarize several closely related grain voices rather than drawing one particle for every voice.

DENS, FLOW, TURB, and IMPACT summarize current simulation population, movement, turbulence, and event energy. They are readouts rather than separate controls.

1-4 select a slot and show its stored simulation and grain state.

Copy / Paste copies or pastes the complete selected slot state.

Random generates new values for the eleven slot-controlled parameters while leaving the three global level controls unchanged.

CLK OFF stops automatic stepping. Manual slot changes and randomization still use Slew.

CLK INT runs from the internal clock. Rate is displayed in Hz.

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

Slew sets interpolation time between slot states. Each parameter has an independent interpolation lane.

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

Holding a parameter while slots advance writes that value into every incoming slot and prevents that control from jumping. Other parameters continue their existing slew.

Preset arrows step through available presets and wrap between the first and last entries.

Preset name opens the preset browser.

Name generates a preset name.

Save writes the complete state. Saving without first generating a name creates one automatically.

Factory / User / Starting Points / Favorites filter the preset browser.

Versioned Save writes a numbered copy when the current preset has changed.

Folder opens the preset directory for external renaming or deletion.

Refresh reloads externally renamed or deleted preset files.
