When receiving a trigger-change from 0 Volts to +5 Volts at the trigger input, the three states or phases
of the started envelope are executed.
1. Attack-phase: In the attack-phase, the envelope rises expotentially from zero to its maximum
value within the adjusted attack-time. It is immediately followed by the hold-phase.
2. Hold-phase: Within the hold-phase, the maximum value is held over the adjusted hold-time.
It is immediately followed by the release-phase.
3. Release-phase: In the release-phase, the envelope falls expotentially back to zero and re-
mains there until the next trigger.
The curves, as well as start- and final level of the envelopes are independent from the adjusted times.

9.5.1 The re-trigger-mode

In re-trigger-mode, an incomming trigger resets the envelope-curve back to zero and restarts the at-
tack-phase again, even if the final point of the curved has not yet been reached, as shown in
