The 1003 Dual Envelope Generator is an authentic 16HP imitation of the classic “System 2500” circuit from the '70s compatible with a standard Eurorack case. Containing two identical envelope generators for creating control signals, it has four adjustable parameters; * Attack * initial Decay * Sustain * final Decay Each envelope is initiated by Gate and Trigger signals. Switchable between 2 operating modes for added flexibility. Single trigger mode uses only the gate signal to control the envelope. Multi trigger mode uses a positive trigger pulse to re-trigger the envelope while a Gate signal is present. Manual gate operation via front panel push button with LED for gate signal indication.
