The circuit of the Eurorack Module Intellijel Dual ADSR is based in part on the Roland SH-101 / System100m design with several enhancements.

Intellijel Dual ADSR features:
– 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.

Snappy, classically analog envelopes with visually intuitive controls. Add trigger buttons, cycling and a variety of control voltage outputs, then double it:now you’ve got the Intellijel Dual ADSR.

Get In Shape
We tend to prefer sliders for our Intellijel Dual ADSR envelope generators because they provide a clear visual representation of the modulation shape. This circuit is based in part on the Roland SH-101 / System 100m design with several enhancements.
