FmSynth

Audio

Two-operator FM synthesizer with ADSR envelope.

Classic FM synthesis with a carrier and modulator oscillator. The modulator frequency is set as a ratio of the carrier, and the modulation index controls harmonic richness. Drive it with notes_in from any note source, and use NoteBreakout when downstream envelopes or filters need shared per-voice control lanes.

Tips

Integer mod_ratio values produce harmonic timbres; non-integer values create bell-like inharmonic sounds.

Parameters

Name	Type	Range	Default	Description
mod_ratio				Modulator frequency as a multiple of the carrier.
mod_index				Depth of frequency modulation. Higher = more harmonics.
