GM 16-23 additive Hammond drawbars (footage ratios + key-click + percussion + Leslie; free-reed accordion/harmonica). GM 48-55 Szabo JP-8000 7-saw supersaw (string/synth-string pads) + Klatt formant choir (real vowel tables, Aahs /a/ Oohs /u/) + orchestra hit. GM 80-95 subtractive synth lead/pad (SVF + filter-env + chorus; chiff/charang/fifths/sub variants; metallic/sweep/halo pads). New engines: ORGAN, SUPERSAW, FORMANT. Every program stochastic (organ mul 0.3, pads/choir ~0.9). Local cc clean, seed-varied, existing families byte-identical (no regression).
