Ableton/Live/UG/31 Instrument Reference/09 Operator/10 The Complete Parameter List
- Every parameter, grouped by where it sits; the Info View also explains any control under the mouse.
31.9.10.1 Global Shell and Display
- Time — scales all envelope rates. Tone — high-frequency content; brighter means more aliasing risk. Volume. Algorithm — oscillator connections.
- Voices — oldest notes are cut when exceeded. Retrigger (R) — retrigger a playing note instead of adding a voice.
- Interpolation — off sounds rougher, especially noise, and saves CPU. Antialias — off saves CPU.
- Time < Key — faster envelopes for higher notes. PB Range.
- Pan, Pan < Key (low notes left, high right, as for pianos), Pan < Random.
31.9.10.2 Modulation Targets
- For MIDI routings, the LFO's Dest. B and the pitch envelope's Dest. B: Off; OSC Volume A–D; OSC Crossfade A/C and B/D; OSC Feedback (only unmodulated oscillators); OSC Fixed Frequency; FM Drive (level of all modulators); Filter Frequency; Filter Q (Legacy); Filter Res; Filter Morph; Filter Drive (not with Morph); Filter Envelope Amount; Shaper Drive; LFO Rate; LFO Amount; Pitch Envelope Amount; Volume; Panorama; Tone; Time.
31.9.10.3 Pitch Shell and Display
- Pitch Envelope On — off saves CPU. Pitch Env — ±100%; 100% follows the envelope's levels, negative inverts.
- Spread, Transpose (affects playing notes), Glide (G) and Glide Time; legato glides don't retrigger envelopes.
- Destination A–D and LFO switches with Amount A; Destination B with Amount B.
31.9.10.4 Filter Shell and Display
- Filter On (off saves CPU), Filter Type, Circuit Type, Freq, Res (resonance for low- and high-pass, width for band-pass and notch).
- Freq < Vel; Freq < Key, where 100% doubles cutoff per octave around C3; Envelope, where 100% can shift about nine octaves.
- Flt. Drive, Morph, Shaper, Shp. Drive, Dry/Wet.
31.9.10.5 LFO Shell and Display
- LFO On (off saves CPU). Waveform — all band-limited to avoid clicks.
- Range — Low covers 50 seconds to 30 Hz, Hi 8 Hz to 12 kHz, or Sync to tempo.
- R, Rate, Amount, Destination A–D and FIL with Amount A, Destination B with Amount B.
- Rate < Key — at 100% the LFO doubles per octave like an oscillator. Amt < Vel.
31.9.10.6 Oscillators A-D Shell and Display
- Osc On. Coarse — whole-number ratios for harmonic relationships. Fine — fractions for inharmonic ones.
- Fixed, Freq and Multi — a constant frequency, Freq × Multi in Hz.
- Level — on a modulator, higher levels usually mean brighter or noisier sounds.
- Envelope/Oscillator display switches; 16/32/64 partials; Wave; Repeat.
- Feedback — self-modulation of an unmodulated oscillator, also shaped by its level and envelope.
- Phase (one full cycle), R.
- Osc < Vel with Q; Vel and Key for level, centered on C3. Velocity on modulators makes timbre follow touch.
31.9.10.7 Envelope Display
- Attack — linear on oscillator envelopes, shapeable on filter and pitch. Decay — exponential on oscillators. Release — from the current level at note-off to End, or to -inf dB on oscillators.
- Initial, Peak, Sustain, and End (LFO, filter and pitch only).
- Loop mode — Loop, Beat, Sync or Trigger. Repeat — beat time for Beat and Sync. Loop Time — return from sustain to initial.
- Time < Vel — scales segments, not Beat or Sync times.
- A.Slope, D.Slope, R.Slope — filter and pitch envelopes.
31.9.10.8 Context Menu Options for Operator
- Copy parameters between oscillators; set all envelope levels to maximum, minimum or middle; harmonics editor options (even or odd, Normalize, export .ams); Play By Key; and Enable Per-Note Pitch Bend, on by default.
