Chaos-Driven Composition

Use a Logistic Map node (r between 3.57 and 4.0 for chaotic behavior) or a Henon Map to generate deterministic chaotic sequences. These are not random — they are fully determined by the initial parameters — but they produce sequences that are effectively unpredictable and never repeat.

The output values (typically 0.0–1.0 for Logistic Map) need to be mapped to musical ranges. Connect to a Map Range node to convert to midicents (e.g., map [0, 1] to [4800, 8400] for a 3-octave range). Then pass through Microtonal Quantize to snap to your desired temperament (12 for semitones, 24 for quarter-tones).

The Henon Map is especially powerful because it outputs two correlated sequences (X and Y). Map X to pitches and Y to rhythm durations (via Map Range and Quantize Rhythm) so that both dimensions of the music emerge from the same chaotic process. Small changes to the initial parameters (r, a, b, x0, y0) produce radically different musical results, making these nodes excellent for generating variations.
