Black Dual EG/LFO

Two full ADSR envelope generators, set one at a time, or two simultaneous AD/ASR envelopes, and a looping LFO whose shape you draw with the knobs, in 10 HP from Erica Synths' Black Series, retired.

Key features

• The 1 / 2 switch assigns the four knobs to the first or the second envelope, the lamps 1 and 2 showing which; a knob takes over when it reaches its stored setting
• A, D, S/A2 and R/D2 (RATE): ADSR, or in 2xAD the second envelope's attack and decay, or the LFO's rise, fall, pulse width and rate
• S / L / LFO for each: short (attack 0.125 s) or long envelopes (attack 2 s, release 5 s), or an LFO, 0.2 to 30 Hz
• ADSR / 2xAD; a lamp for each stage
• GATE, TRIGG, OUT and INV.OUT for each; GATE2 normalled to GATE1
