Pitch weights — interval profile Randomize

Weight each interval by how often you want it to follow the current note. Weights are whole numbers of any size; each one is converted to a percentage of the row total. With nearest-neighbor octave placement, large intervals usually sound as their inversions — 11 reads as a descending semitone.

▶ Per-pitch row overrides

The interval profile applies to all twelve rows. Override a single row to set exact destination weights for one starting pitch class.

Chain order

Order First order — next pitch depends on the current pitch Second order — current pitch plus the last interval

Momentum +30

← Reverse (gap-fill) First order only Continue →

Momentum reweights the first-order row by what just happened. Positive values favor continuing in the same direction, and favor them more when the interval size also repeats. Negative values favor turning around after a leap. At 0 the second-order term vanishes and the chain is purely first-order.

Register & collection

Lowest note

Highest note

Start on

Each new pitch class is placed at whichever octave sits closest to the previous note, inside this range.

Pitch-class collection (optional)

Accepts 0,2,4,5,7,9,B, 0 2 4 5 7 9 B, or unseparated 02457 9B. Hex throughout: A = 10, B = 11. Pitch classes outside the collection get weight zero.

Rhythm weights Randomize

Each event draws a duration from these six weights. Durations that would cross a barline are split and tied automatically.

Pitches follow the Markov chain; durations are drawn independently from the rhythm weights. Output is MusicXML 4.0, readable by MuseScore, Finale, Sibelius, and Dorico.
