fm-voice - FM Voice
Two-operator FM synthesis — carrier and modulator with index control.
Overview
Section titled “Overview”A two-operator FM synthesis voice. The modulator oscillator feeds into a multiply node that controls modulation index (depth), then into the carrier oscillator’s frequency input via an add node. Changing the modulator frequency and index creates rich harmonic and inharmonic spectra from just two oscillators.
