Dual Envelope/Function Generators

The Model 180 Dual Attack Generator is composed of two ASR envelopes. The length of the sustain phases, here called note duration, can be determined by either trigger respectively gate signals or potentiometers. With the knobs turned completely counterclockwise, the envelopes feature an AD characteristic. While attack or note duration phases are active, the modulators can't be retriggered. Thanks to this, it is possible to use the Model 180 as an unconventional clock divider. The circuit produces linear voltage curves. Small time values lead to very punchy results.

  • Two identical ASR envelopes
  • Two outputs per envelope
  • 3U Eurorack module, 14 HP wide, 45 mm in depth
