Ableton/Live/UG/31 Instrument Reference/03 Drift/02 Oscillator Section
- Two oscillators, pitch modulation, a waveform display, an oscillator mixer and a noise generator.
31.3.2.1 Oscillator 1
- Waveforms: Sine, Triangle, Shark Tooth, Saturated, Saw, Pulse, Rectangle. Shark Tooth is based on a classic Moog shape; Saturated suits bass.
- Oct transposes by octaves. Shape alters the harmonics, somewhat like pulse-width modulation, differently per waveform; the Waveform Display shows the result.
- Shape Mod Source — Env 1, Env 2/Cyc, LFO, Key (more modulation for higher notes when positive), Velocity, Modwheel, Pressure or Slide, with an amount of -100% to 100%. Shape Mod can move the waveform even when Shape is 0%.
31.3.2.2 Oscillator 2
- Waveforms: Sine, Triangle, Saturated, Saw, Rectangle. Oct in octaves, Detune in semitones.
31.3.2.3 Pitch Mod
- Two sources modulate both oscillators' pitch, chosen from the same list as Shape Mod, each with -100% to 100%. An LFO in Ratio mode on pitch can produce FM tones.
31.3.2.4 Waveform Display
- Shows the combined output of Osc 1, Osc 2 and noise as you edit.
31.3.2.5 Oscillator Mixer
- Switches and gain for Osc 1, Osc 2 and white Noise.
- With filtering on, raising gain drives the filter's two saturation points, before and after the filter, for analog-style distortion: the first engages above the default -6.0 dB, the second above 0.0 dB.
- Arrow toggles beside each gain send that source through the filter; off bypasses it.
- R — Retrigger resets both oscillators' phase on each note; off lets them run free.
