A-143-1 Complex Envelope Generator / LFO

Doepfer's complex envelope generator in 28 HP: four attack/decay units chained by their comparators into an envelope of up to eight segments, or an eight-stage LFO, mixed with a polarizer each.

Key features

• Four units, each with Attack, Decay, Threshold and a Mix Polarizer
• An AD / LFO switch per unit
• Per unit: Trig. In, EOA (end of attack), Cp (comparator) and Env outputs, an Env and a comparator lamp
• Each Trig. In normalled to the preceding unit's Cp: unpatched, an eight-stage LFO
• Mix Out: the four units added or subtracted by their polarizers
• Internal jumpers per unit: gated (AR) or triggered (AD), Env before or after the polarizer
