Polyrhythm

Game Design Document

Pitch

Three percussion parts share one clock. Set hits per cycle to hear and see a polyrhythm. Play freely, match three Game Mode objectives, or record a looping portrait clip.

How it plays

Three always-on rhythms, each from 1 to 12 hits. Defaults: 1 / 1 / 1 at 120 BPM. The title shows N AGAINST N AGAINST N in orange, green, and purple.

Freestyle is free play. Game Mode shows targets. Press Play, match them, then press Check.

  1. 12 / 3 / 3, Volume 5.
  2. 12 / 3 / 3, Volume 5. Sounds: Hi-Hat Closed, Deep Snare, Brutal Kick.
  3. 12 / 4 / 3, Volume 5. Same sounds as objective 2.

After the final successful Check, congratulations appears for 3 seconds or until OK. Freestyle resumes with current values kept.

Controls

VFX

Start with an empty list. Add Glow, Haze, or Vortex from a dropdown, one of each. Each has its own Amount and can be removed independently. Shared oscillators drive all active effects. Vortex is a static tunnel lit by the three moving dots.

Sounds

13 sounds: Tight Snare, Deep Snare, Kick, Brutal Kick, Ride, Ride Bell, High Tom, Mid Tom, Floor Tom 1, Floor Tom 2, China, Hi-Hat Closed, Hi-Hat Open.

Defaults: Hi-Hat Closed, Deep Snare, Kick.
