BELL is a two-operator FM voice voiced as a bell. A gate fires it and the sound does what real struck metal does: the attack clangs with inharmonic energy, then the partials fall away faster than the body and the tail rings pure. BRIGHT sets the modulation depth, and its envelope decays ahead of the body envelope — that split is the whole trick.

RATIO steps the modulator through eight ratios, from consonant and glassy to clangorous and gong-like. TUNE sweeps the carrier from 40 to 900 Hz and tracks V/OCT, so the bell plays melodies as happily as it marks time. DECAY runs from a 0.1-second tick to a six-second ring. Every knob has CV, so ratio, brightness, and decay can all move per hit.
