The Multi stage envelope is a 5-segment time and level envelope with selectable sustain segment.

A logic control signal is used to start and hold the envelope for as long as the logic signal is high. A green
LED indicates when a gate signal is received.

Click on the buttons to switch between Bipolar with linear time segments characteristics, Unipolar with
exponential attack time segment(s) characteristics, or Unipolar with linear attack time segment(s) char-
acteristics. Note that it is only the attack segments of the unipolar envelopes that can be selected to be
linear or exponential. The decay segments of the unipolar envelopes are always exponential. An attack
segment is defined as a level shift from a low value to a higher value, and a decay segment is defined as a
level shift from a high value to a lower value.

By turning the rotary knobs L1 to L4 you can set the amplitude of each of the four level segments in the
envelope. The levels can be either unipolar or bipolar as described above. The levels are displayed in units
in the corresponding display box. Ranges: 0 to +64 units (unipolar) or -64 to +64 units (bipolar).

Here you set the times between the four levels plus a fifth release time from L4 to zero. The times are
displayed in milliseconds or seconds in the corresponding display box. Ranges: 0.5 ms to 45 s.
short times can produce clicks in the sound. This is only normal according to physics theory. To elim-
inate any click, just increase the times slightly.

The info graph shows an approximation of the envelope gain curve. The yellow line represents the sustain
level, which is not defined in time since it depends on the gate signal hold time. If 'bipolar' is selected, a
horizontal broken line represents the 0 units output level.

By clicking on the up and down arrow buttons you define the sustain segment. This segment can be any
of the four level segments, or, if you wish, none at all. The sustain segment works like in an ordinary
ADSR envelope, i.e this is the level that sustains as you hold down the key(s). After releasing the key(s)
the envelope will continue till the end of T5. Range: None and L1 to L4.
