Doepfer - A-140-1 ADSR (Silver)

The Doepfer A-140-1 is a classic, full-range ADSR envelope generator designed for versatility and speed. It offers three selectable time ranges, making it suitable for everything from ultra-snappy transients to slow, evolving modulation.

In addition to the standard Gate input, the module features a Retrigger input—useful for restarting the envelope even while it’s in progress. A three-way switch allows you to toggle between Low (L), Medium (M), and High (H) time ranges to suit different modulation needs: long fades, general use, or fast percussive clicks.

Three outputs are provided: two normal outputs and one inverted, making the A-140-1 an ideal source for both unipolar and bipolar modulation. Whether you're shaping amplitude, filter frequency, or any voltage-controlled parameter, the A-140-1 delivers reliable, musical results.
