Ableton/Live/UG/31 Instrument Reference/01 Analog/02 Oscillators
- Modeled oscillators, so no aliasing. Each has an on switch (Osc 1, Osc 2) and a level slider.
- F1/F2 — balance between Filter 1 and Filter 2; centered sends equally.
- Shape — sine, sawtooth, rectangular or white noise. Rectangular enables Pulse Width (100% is a square with odd harmonics only; low values sound thin), which an LFO can modulate.
- Octave, Semi, Detune — tuning; Detune moves in cents, up to 300 cents either way.
- Pitch Mod — LFO amount, and Key: how far pitch follows the keyboard. 100% is equal temperament, 0% ignores note pitch. C3 always plays the same frequency, so oscillators with different Key values move further out of tune with each other the farther you play from C3.
- Pitch Env — Initial pitch and the Time to glide to the final pitch.
- Sub/Sync — Sub adds an oscillator an octave down (square for saw or rectangle, sine for sine, off for noise) at a set Level. Sync restarts the waveform from a hidden oscillator whose rate rises with Ratio; 0% has no effect. Mapping Ratio to a mod wheel is a suggested use.
