Intellijel - Tangrams

Dual ADSR/VCA with Cycling Gate Pulsers Tangrams, like our Dual ADSR before it, is a dual analog core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, we have added a voltage-controlled pulser circuit to link the triggering of two envelopes - allowing for delayed one-shots, cycling organic envelopes, and more. In addition, we've added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you'd like to envelope - freeing up your other VCAs. The Pulser The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot
