Operator

Ableton

Where to get itIncluded with Ableton Liveableton.com

Operator is an advanced FM synthesizer that combines frequency modulation with subtractive and additive synthesis using four multi-waveform oscillators. Each oscillator can modulate others to create complex timbres, supported by a filter section, LFO, and comprehensive envelope controls. It excels at both classic FM sounds and experimental textures through its eleven predefined algorithms and extensive modulation routing.

Written from the manual and checked against it. How we check

Key Features

01Four multi-waveform oscillators with FM modulation capabilities
02Eleven predefined algorithms for oscillator routing and connections
03Built-in waveforms: sine, sawtooth, square, triangle, noise, plus digital variants (Sine 4/8-bit, Saw D, Square D)
04User waveform editor with harmonic drawing (16, 32, or 64 harmonics)
05Five filter types: low-pass, high-pass, band-pass, notch, and Morph filter
06Five analog-modeled circuit behaviors (Clean, OSR, MS2, SMP, PRD)
07LFO with seven waveform options including sample-and-hold and noise
08Seven envelopes with looping, beat, sync, and trigger modes
09Up to 32 voices of polyphony with legato monophonic mode
10Polyphonic glide and stereo spread (chorus) functionality

Things to Try

  • 01Use the LFO with a noise waveform to create fantastic hi-hat and snare percussion sounds
  • 02Apply the pitch envelope to the LFO and enable looping to serve as a second LFO modulating the rate of the first
  • 03Loop the pitch envelope and its own LFO envelope together to create a third LFO modulating the intensity of the first
  • 04Set Voices to 1 for monophonic sounds like flutes, which enables legato playback where envelopes do not retrigger between notes
