Synthrotek's MST Dual Envelope includes a double attack/decay or attack/sustain/release envelope for modular synthesizers in Eurorack format. Both envelopes can be used separately but also influence each other. The envelopes in Synthrotek's MST Dual Envelope are identical. You can work as an attack/decay envelope or as an attack/sustain/release envelope using a toggle switch. The length of the envelope can also be defined via a toggle switch. Both envelopes have an output level to adjust the intensity of the envelope.
The highlight of Synthrotek's Dual Envelope is that a trigger is generated at the end of the envelope curve. The trigger can be picked up at the EOC output. If no cable is plugged into the EOC output (End Of Cycle), the envelopes trigger each other, resulting in very interesting envelopes. In addition to the normal output, an output with inverted signal is also available. Via the +5V switch an offset is added to the inverted output which partly raises the output signal into the positive voltage range.
