ENV1/ENV2 section

  1. Attack
  2. Attack Curve
  3. Decay
  4. Sustain
  5. Release

An envelope section generates an envelope signal for the oscillators, the filter and the amplifier as a modulation source. Exciton has two envelopes (ENV1 and ENV2) and each envelopes have the identical function.

An envelope generator outputs a signal as shown in the following figure on MIDI note-on and note-off messages. It is used as a modulation source for changing pitch, cutoff frequency and so on.

ADSR description

Attack Time
Time between receiving the note-on message and the end of attack.
Decay Time
Time between the end of attack and the end of decay.
Sustain Level
Signal level after decay time.
Release Time
Time between receiving the note-off message and release to zero.

3.6.1. Attack

Set the attack time.

3.6.2. Attack Curve

Sets the attack curve.

Attack curve can be selected from convex, linear and concave.

Selecting the attack curve is useful for changing the perceptual "speed" of sounds. For example, convex curve fits to the fast attack percussions. On the other hand, concave curve is suitable for slow strings.

3.6.3. Decay

Sets the decay time.

3.6.4. Sustain

Sets the sustain level.

3.6.5. Release

Set the release time.
