Envelopes
Filter/Amp/Osc 1/Osc 2 Envelope
A (Attack Time)
(ATTACK)
[0.0000…90.0000 seconds]
This sets how long the envelope takes to rise to the peak level.
D (Decay Time)
(DECAY)
[0.0000…90.0000 seconds]
This sets how long it takes to settle from the peak to the
Sustain
level.
S (Sustain Level)
(SUSTAIN)
[–100…+100 (Filter, Osc 1/2) or 0…+100 (Amp)]
This sets the level at the end of the
Decay
time. Once it reaches the
Sustain
level, the envelope will stay there until note-
off, unless it is restarted via the
Trigger Source
. The Filter and Osc 1/2 Envelopes can have either positive or negative
Sustain
levels, while the Amp Envelope has only positive
Sustain
levels.
R (Release Time)
(RELEASE)
[0.0000…90.0000 seconds]
This sets how long it takes the envelope to fall to 0 after releasing a note.
Filter/Amp/Osc 1/Osc 2 Envelope Curve
Often, envelopes are pictured as being made out of straight lines. In actuality, they are more likely to be made out of
curves.
In other words, each segment’s level will change quickly at first, and then slow down as it approaches the next point.
When controlling natural aspects of sound such as volume, brightness, and pitch, this tends to sound better than
straight, linear segments. (See note below regarding Wavetable modulation.)
Classic analog synth envelopes made these curved shapes naturally. The modwave goes a step further than vintage
synths, however, and lets you control the amount of curvature separately for each envelope segment.
