Ableton/Live/UG/31 Instrument Reference/01 Analog/06 Envelopes
- Besides the oscillator pitch envelopes, each filter and amp has an ADSR envelope, all four with the same controls in the display, plus velocity and looping.
- Attack, with Att < Vel to shorten it at higher velocities; Decay; Sustain (fully left removes sustain, fully right removes decay); Release.
- Env < Vel — velocity scales the whole envelope.
- S.Time — lets the sustain level fall while the key is held; lower is faster.
- Slope — linear or exponential segments.
- Legato — a note played while another is held continues that note's envelope.
- Free — skips sustain and goes straight from decay to release, so notes have equal length; suits percussion.
- Loop:
- Off — plays once.
- AD-R — attack and decay repeat until release.
- ADR-R — attack, decay and release repeat while held.
- ADS-R — no looping, but attack and release play once more on key release, which can mimic audible dampers.
- With Free on, AD-R and ADR-R act as if the key is always held.
