What this does

Praat script.

Process Description: This script adapts the Random Walk model from the previous melody generator to focus purely on timbre and texture within a metrically consistent rhythmic grid. Instead of changing scale degrees, the Random Walk controls the frequency of a percussive sound with every step.
