5.15 Envelopes
The general principle is that a set of envelopes are available in Synth which
can be used for modulation patching but are also have some default
patching in the synth engines for control of the lter and amp. The
modulation details are covered elsewhere.
Envelope Concepts
An envelope shapes the journey of the sound over its lifecycle, from an
initial note on state and later to the note off Behavior.
Synth Envelopes
Various envelope types exist with Synth adopting the ADSR model, which
controls the attack, decay, and release times and a sustain level. With an
extended release and short decay time, you can hold a note that decays
faster than if you tap it because then it enters the release phase. There are
up to 3 Envelopes per Synth voice. A default preset model typically controls
the Filter cutoff from one ADSR Envelope and the Amp volume level from
another ADSR Envelope. An optional Aux Envelope in some presets is also
freely patchable. All Envelopes can be patched individually to add other
destinations.

Parameter Description
Attack
The time the sound takes from the note on to reach its maximum
level. This is ranges 0.00 - 10 Seconds in the Synth envelopes.
Typically short attacks are used for percussive sounds and longer
duration to build sound gradually for example a pad.
Decay
The time the sound takes from its maximum level to settling at the
sustain level. This covers the natural decay after an initial ‘hit’ or
‘pluck’ of an instrument. This is ranges 0.00 - 10 Seconds in the
Synth envelopes.
Sustain
The level at which the sound is sustained while the note on state
continues. This would remain high for sustained chords, pads or
drones and may drop low for percussive sounds. 0-100%
Release
The time the sound takes from its sustain level to reach zero once
the note is lifted off. This represents the natural decay and fade
out at the end of a note. This is ranges 0.00 - 10 Seconds in the
Synth envelopes.
