MUSICAL FEATURESCeis is an envelope module that adds the functionality of modularity to the classic ADSR envelope.
Each fader controls Attack time, Decay time, Sustain level, Release time, and voltage can be controlled from the bottom jack. Moreover, the upper part has a gate output that turns on only during the time it is in each segment. It also has a trigger output (bottom center) that issues a short trigger at the moment of moving to the next segment. If you use this function, it also works like a trigger burst generator by reducing each time. The large knob allows you to continuously change the curve shape of the envelope from straight to exponential (exp).
The lower left is the gate / trigger section. The envelope can be activated by the gate signal or manual button. When the switch is set to the Gate position, the envelope will sustain at the specified level while the gate is on. In the Gate position, if the gate turns off during an attack, the envelope will end without waiting for the attack to complete. When the switch is set to the TRIG position, the attack starts at the moment the gate input turns on, and one cycle until release is performed without sustaining. In this mode the gate length has no effect on the envelope.
