EFM1
Logic Pro EFM1 overview
The 16-voice EFM1 is a simple but powerful frequency modulation synthesizer. It can
produce the rich bell and digital sounds that frequency modulation (FM) synthesis has
become synonymous with.
If you’re new to synthesizers, see Synthesizer basics overview, which will introduce you to
the terminology and give you an overview of various synthesis systems and how they work.
EFM1 is divided into several areas.
Global parameters: The top section contains parameters that set the overall tuning of
EFM1. Further controls enable you to set the Glide (portamento) time, limit the number
of voices, and thicken the sound with Unison. See Logic Pro EFM1 global parameters.
