Each row in the grid is a track. There are three track types, each with its own color chip in the row header:

• SMPLR Sampler — plays an AudioBuffer with optional pitch-shifting and granular time-stretching.
• ACID Acid synth — a true 4-pole tanh-saturated ladder filter implemented in an AudioWorklet.
• WT Wavetable — 6 morphable tables, ADSR envelope, stackable unison voices.

Switching a track's type

Click the type chip in the track header → pick Sampler, 303 synth, orWavetable. If the track's name was the original default (e.g. "kick"), it is replaced with the first built-in preset name for the new type. Custom names are kept.

Track-header controls (left column)

• Color dot + type chip + name — click the name to select the track, double-click to rename. × removes the track from every pattern.
• Step-count input — per-track length 1–64 (drives polymeter).
• Volume slider — 0–100%.
• M mute / S solo (any soloed track silences the rest).
• 🎲 dice menu — randomize this track's steps / parameters.
• Q-button (live quantize strength) — 1.0 snaps live taps to the grid; 0.0 keeps the exact fractional offset; in-between is partial pull.
• Sample picker / ⬆ load / ✎ edit — sampler tracks only.

Adding tracks

The + Add Track row at the bottom of the grid creates a new sampler track. Its name and sample default to "Track N"; switch it to a synth via the type chip.
