Envelopes

The MicroWave II/XT/XTk's envelopes allow you to manipulate sound parameters via rate
or timed modulations. The MicroWave II/XT/XTk offers four independent programmable
envelopes for every sound program:
• A filter envelope with ADSR characteristic
• A volume envelope with ADSR characteristic
• A wave envelope with 8 different times and levels (multi segment envelope)
• An additional free multi segment envelope with 3 different times and levels and a
release time and release level
Most traditional synthesizers feature ADSR envelopes. These envelopes are made up
of four parameters that determine their response: Attack, Decay, Sustain and
Release. The following diagram illustrates the structure of an ADSR envelope:
The envelope is started by pressing a key. It ascends to its maximum value at the rate
determined by the Attack parameter. It then descends at the rate determined by the
Decay value until it reaches the predetermined Sustain value. It remains at this
value until the key is released. The envelope then descends to zero at the rate
determined by the Release parameter.

Filter Envelope

This envelope is designed to control the filter but can also be used for other modulations.
The following parameters determine the envelope's response.
Filter Env
Attack
Determines the attack rate or amount of time it takes for a signal to go from zero to
maximum level.
Decay
Determines the decay rate or amount of time it takes for a signal to reach the Sustain
level.
