Legato Mode
This mode is used to choose how the envelope generator reacts when a new note is played before
the end of the preceding one. When this occurs, two strategies are possible. The first one consists in
triggering a new envelope, from the attack phase, when the new note is played. The second consists
in applying the current envelope signal of the first note to the second note which produces a legato
effect. The first strategy is adopted when the Retrig button switched on while the second is applied
when it is in its off position. Note that when the keyboard is in polyphonic mode and the envelope
generator in retrig mode, the envelope generator behaves in a monophonic manner, reacting to a
logical OR between all the gates signal from the different notes played on the keyboard. In other
words the envelope generator is only triggered by the first note played on the keyboard and then
remains in the sustain stage until the last note is released.
Loop Modes
The envelope generator features three loop modes: AD, ADR and Once. These modes allow the
envelope to cycle between several stages of the envelope until the key is released and are selected
from the Loop drop-down menu.

In the AD mode, the envelope begins with the attack and decay phases as usual, but rather than
holding the sustain level, it repeats the attack (from the sustain level) and the decay phases until
