EFM1

EFM1 is a 16-voice frequency modulation synthesizer in Logic Pro that produces rich bell and digital sounds characteristic of FM synthesis. It features a multiwave modulator oscillator and sine wave carrier oscillator at its core, with intuitive controls for tuning ratios, modulation, and sound shaping.
