Ableton/Live/UG/31 Instrument Reference/09 Operator/01 General Overview
- A central display sits between two sides of shell. The left shell has the four oscillators; the right has LFO, filter, pitch and global. Touching a shell control shows that section in the display, so levels and frequencies are reachable together while envelopes and waveforms sit in each display.
- The triangle at the top left folds the display away.
- Each oscillator either outputs audio or modulates another. Eleven algorithms, picked in the global display, set the connections; signal flows top to bottom in each icon. The algorithm can be mapped, automated and modulated.
- Beyond the usual FM sines, Operator offers other waveforms, two noises and a drawable partial editor. Ableton suggests exploring FM without the filter first, since many classic FM synths had none.
