WHAT THE CHIP REALLY PLAYS

The instrument catalogue.

Every preset a user can pick - the lead, chord and bass programs and the percussion kit, for every chip - played as one fixed probe: pitch C4, velocity 100, held for 700 ms of a 1200 ms render. What differs below is only what the chip does with it: an envelope and a spectrum measured from the render itself, never from the instrument's declared parameters. The method is in scores/instruments/generate.mjs.
