Eurorack envelope generator

The A-140 is a fast ADSR type envelope generator with both positive and inverted outputs as well as a retrigger input. The coarse time range of the A-140 can be selected from three settings by a rocker switch.

The A-140 features a gate input for starting the envelope as well as retrigger input fir immediate retriggering the envelope from the startpoint, no matter if the envelope cycle has been finished or not.

A switch selects between three time ranges:

  • L = low. Intended for slow envelopes with long times
  • M = medium. The universal standard setting for most applications
  • H = high. Very short times, from ultra-short clicks to percussive envelopes
There are two normal and one inverted output.
