Nota Grain
Nota Grain is a granular synthesizer. It scans a loaded sample with a cloud of short overlapping grains — freeze on a spot for shimmering textures, scan slowly for evolving drones, or let the keyboard drive the read position. It ships with a procedural default sample, so it makes sound before you drop in your own.

Overview
Section titled “Overview”sample ─▶ [Position / Scan] ─▶ grain cloud (Size · Density · Spray · Pitch · Spread) ─▶ filter ─▶ amp ─▶ outA read position moves through the sample. Grains of a chosen size spawn at a density (overlap), each sprayed randomly around the position, pitched by the note and spread across the stereo field. The cloud then runs into a filter and an amp envelope.

Interface
Section titled “Interface”The card (mockup 2d) stacks a waveform, a scan strip and a tab rail.
- Waveform — the sample with the current grain window highlighted and live playheads for the sounding grains; a grains-per-second readout sits top-left.
- Scan strip — the scan mode (Scan · Freeze · Key) and the
POSITION,SCAN(speed) andSPRAYsliders, reachable from any tab. - Tab rail (left) — Grain · Pitch · Variation · Filter · Amp.
The tabs:
- Grain — the grain shape (four window shapes) and Size · Density · Spread.
- Pitch — Coarse and Fine tuning.
- Variation — per-grain Pos · Pitch · Pan randomisation.
- Filter — type (LP · HP · BP) with Freq · Reso.
- Amp — the A/D/S/R amplitude envelope.

Tips & recipes
Section titled “Tips & recipes”- Frozen pad: set the scan mode to Freeze, raise
SizeandDensity, and add a littleSprayandSpreadfor a lush, static cloud. - Evolving texture: switch to Scan with a slow
Scanspeed so the read point drifts through the sample. - Playable sampler feel: use Key mode so the read position tracks the notes you play.
- Grit and shimmer: nudge
Pitch Rndup for detuned, chorused grains.
