Features
Continuously captures live input into a circular buffer. Grains draw from the live stream in real time - no pre-recorded samples needed.
Expressive 2D control surface. X axis controls position/scatter, Y axis controls grain size and density. Touch-and-drag for live performance.
Record and loop your XY pad movements. Creates evolving, organic automations that loop in sync with your session.
Snap grain pitches to a musical scale. Produces melodic, tuned textures from any sound source - even noise or percussion.
Real-time visualization of the capture buffer with active grain position indicators. See exactly where grains are reading from.
Built-in stereo delay and reverb tailored for granular textures. Spread grains through space without a separate FX chain.
Modulate grain density, size, or pitch from the input dynamics. Quiet passages trigger sparse grains; loud passages trigger dense clouds.
Pool-based grain scheduling with configurable polyphony. Smooth, glitch-free grain triggering even at maximum density.
Factory presets from subtle shimmer to extreme texture. Full user save/load so you never lose a great sound.

FAQ
Penumbra introduces minimal latency from grain scheduling (typically under 10ms). Unlike STFT-based plugins, it does not require large block processing, so latency is low enough that PDC compensation is usually not needed.
Penumbra is primarily a live-input granular processor - it captures the audio passing through it in real time. Sample file loading is planned for a future version.
Press Record, then move the XY pad freely. When you stop recording, the movement loops continuously at the length you recorded. The loop syncs to your DAW's transport so it stays in time.
