FEG

An analogue ADSR envelope generator in 4 HP, built for short, snappy contours: a very exponential course with rounded edges. Two time ranges, fast and slow, are chosen with the F/S button or remotely with a voltage on the S/F 1V input. LOOP cycles the envelope from attack to release, and 1SHOT plays the whole envelope from a single trigger. A red MAN button fires it by hand, and the envelope leaves on two outputs, normal and inverted.

Key features

• Attack from 0.2 ms to 10 s, decay and release from 0.4 ms to 30 s, sustain from 0 to 100 %
• Two time ranges, switched by a button or by CV
• Loop mode, from attack to release, with a jumper at the back to reset the loop on each gate or trigger
• One shot mode for trigger signals
• Manual gate button
• Normal and inverted outputs, usable for audio and control voltages
