Ableton Operator

Ableton Operator provides a unique hybrid approach to additive, subtractive, and FM synthesis – and it’s one of the most deceptively powerful softsynths available.

Even so, many musicians shy away from using it fully because FM synthesis remains opaque despite its prevalence for more than 30 years. Fortunately, Operator’s clean interface and streamlined tools make it the perfect synth for getting started with both FM and additive synthesis, so you can start whipping up your own creations with it.

The term ‘operator’ was first popularised with Yamaha’s groundbreaking DX series of synths, where it was generally defined as being an oscillator with its own dedicated amplitude envelope. In modern FM synthesis, configurations of multiple operators are called algorithms. In a nutshell, algorithms govern the interaction between a set of operators, with each algorithm functioning as its own synthesis structure. If you’re a modular-synth fan, think of them as preconfigured cable routings. That is, each type offers different features that make it well-suited to specific applications.

As Operator’s features include multiple synthesis options, the easiest way to get started is with the all-carrier algorithm . While there’s no FM functionality here, it’s great for both analogue-style subtractive synthesis and more
