Intellijel Dual ADSR


The circuit is based in part on the Roland SH-101 / System100m design with several enhancements.

  • Manual GATE buttons
  • Three timing ranges: (1 second, 10second, 1minute A/D times)
  • Normal and inverted outputs
  • End of Decay (EOD) logic output
  • Cycle mode (which GATE logic control)
  • Retrig input (allows re-triggering of the envelope if source gate held high)
  • Dynamic control of the envelope output level (each ADSR is routed through a linear VCA and the control is normalled to +5V via the LEVEL jack.
  • You can patch another control source like an LFO or VELOCITY level from a keyboard to this jack.

    Width: 14HP

    Max Depth: 38mm

    Power: 60mA @ +12V

                  49mA @ -12V
