Quad Complex Envelope Generator & LFO

Overview: Module A-143-1 is a complex envelope generator that consists of 4 Attack/Decay generators. For complex envelope generation the four units can be daisy-chained, i.e. the preceding unit triggers the following unit. The four units can even be used as four separate AD generators (switch position AD) or AD-type LFOs (switch position LFO).

Module A-143-1 contains four separate attack/decay type envelope generators. Each unit can be switched into a free running mode (LFO mode). The slopes are exponential - in contrast to the linear slopes of a normal LFO, and the frequency is defined by both controls. The single AD outputs can be used to control VCAs or VCFs that open one after another corresponding to the AD signals (a little bit similar to the Shepard generator A-191). The default-connection between the four units (CPn = Trig.n+1) can be interrupted by patching cables into the trigger inputs. Consequently the four units can be used as separate AD generators or LFOs. In all cases the mix signal is available (e.g. mix of four AD generators or LFOs with adjustable level and sign).
