Purpose

Groove is a drum-pattern generator. Driven by the timeline, it plays a kit as note lanes, one channel per drum voice, ready for a drum instrument. It covers steady grooves, odd math-rock patterns, broken beats, and dense blasts, with per-voice level and fill controls so you can shape the kit balance.

Use

Wire a timeline clock into Input 0, choose a Mode, and route the out note lanes into Drum or any note-lane drum instrument. Set Density and Complexity for the overall feel, then balance the kit with the per-voice gains. Fillheat controls how often fills break up the pattern.

Inputs and outputs

• Input 0: timeline timeline clock. Required, sets the beat grid.
• Output 0: out emits drum triggers as note lanes, one channel per drum note.

Controls

• Mode: groove, mathrock, broken, or blast.
• Density and Complexity: how full and how intricate the pattern is.
• Gate: trigger length.
• Fillheat: how often and how strongly fills appear.
• Kick, Snare, Hats, Toms, Claps, Perc: per-voice levels for shaping the kit.
• Hatrate: hat subdivision multiplier.
• Oddkick: allow extra off-grid kick placements.
• Seed: repeatable pattern generation.

Notes

• Groove outputs note lanes, so pair it with a drum instrument that reads one channel per note.
• Lower Complexity and Fillheat for a steady backbeat, raise them for busier, more broken patterns.
• Seed makes a generated pattern repeatable from run to run.
