Jev model drives a generative drum demo: 5x5 vision, temperature turns it into a random walk

teropa · x · 2026-09-30

Tero Parviainen shared technical details of a generative music demo driven by the Jev model: it only sees a 5x5 neighborhood and mainly acts when a backbeat is approaching and a snare is needed.

Temperature directly shapes behavior: Jev's "choice" is used deterministically only at t=0; at higher temperatures it samples, and at t=1 it becomes a complete random walk — a fun example of grafting LLM decision-making onto rhythm generation.
