Wave Envelope
The MicroWave II/XT/XTk’s wave envelope features a multi segment characteristic with 8
separately adjustable times and levels.
Multi segment envelopes are extremely flexible modulation sources. Their structure is
made of grouped time/level parameters that allows one to generate an almost free
modulation amount over several time segments. The following diagram illustrates the
structure of a multi segment envelope:
As shown in the diagram, the envelope consists of several single segments. Also the
figure can be divided into a sustain and a release phase. The crossover point between
these two phases can be determined by selecting the corresponding segment number.
The envelope is started by pressing a key. It ascends to the
Level 1
value at the rate
determined by the
Time 1
parameter. In the next time segment
Time 2
the amplitude
moves to the
Level 2
value. The same procedure is processed for the following
segments until the end of the sustain phase is reached. In the shown example
Level 6
is the last value of the sustain phase. The amplitude remains at this value until the key
is released. The envelope then moves on to process the remaining segments until it
finally ends with its last value
Level 8.
In fact you can reduce the number of
processed segments to get things easier. Additionally you can repeat specific
segments by installing loops in the sustain phase as well as in the release phase.
