Page 4: Installation
INSTALLATION Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power supply. We recommend you use Intellijel cases and power supplies. Before installing a new module in your case, make sure your power supply has a free power header and sufficient available capacity to power the module: ●... -

Eurorack case. Ensure the red stripe on the cable lines up with the -12V pins on the bus board. On Intellijel power supplies the pins are labeled with “-12V” and/or a thick white stripe, while others have shrouded headers to prevent accidental reversal. -
Page 6: Overview
OVERVIEW Tangrams is a dual ADSR with a heart… or, in this case, a pulser. It is, perhaps, best understood by mentally dividing its panel into three sections, as shown here: ● ENVELOPE 1 ( RED section ) : The first of two traditional ADSR (Attack, Decay, Sustain, Release) envelope generators. -

0V once the ENVELOPE GATE voltage goes low, The higher the slider, the longer the release time. The slider’s overall range depends on the setting of the ENV 1 SPEED [1.7] switch. Tangrams Manual... - Page 8 Approximate maximum times are: ~10 to 12 s D/R : ~22 to 24 s ● SLOW Long, slow envelope good for pads, drones, and evolving sounds. Approximate maximum times are: ~20 to 27 s D/R : ~45 to 50 s Tangrams Manual...

NOTE: 8V is normalled to this jack by default. So if nothing is patched into it, then ENV 1 OUT [1.D] contains an envelope with a maximum level of 8V. Inputting values above or below 8V will increase/decrease the envelope’s maximum value proportionally. Tangrams Manual... - Page 10 ENV 1 LEVEL [1.C] , and the output of the VCA is sent to the ENV 1 OUT jack. Building a VCA into Tangrams has two benefits: ● It enables you to control the output’s overall amplitude by...

It’s OR’d with the P.TRIG IN [3.C] jack, which performs the same triggering function. Tangrams Manual...
- Page 14 NOTE: Turning on Cycling automatically starts the PULSER, without requiring a manual or external trigger, while turning off Cycling automatically stops it. However, once the PULSER is cycling, P.TRIG IN [3.C] and/or the PULSER’s MANUAL TRIGGER [3.7] will reset the cycle at the beginning of PULSE 1. Tangrams Manual...
- Page 15 ● RIGHT (PULSE 2) : In this position, PULSE 2 generates a HIGH GATE, which lasts for the length of T2 [3.4] , and begins after the completion of PULSE 1. It’s OR’d with the ENV 2 GATE IN [2.A] jack and the ENV 2 MANUAL GATE [2.5] button. Tangrams Manual...

“as long as any one of the inputs is true, then the output is true.” Used in the context of Tangrams, it means “as long as any one envelope gate source is high, then the envelope is gated.” That is, if the MANUAL GATE button is high OR the GATE input is high OR the PULSE is high THEN the envelope is being gated. -

● PULSE 1 is shorter than the GATE IN time RESULT : The PULSER has no effect on the envelope since the GATE IN time is longer than the PULSE 1 time . Tangrams Manual... - Page 19 GATE length determined by ● CYCLE [3.8] = SINGLE ● Envelope’s PULSE SOURCE [3.9 3.10] = P1 ● GATE unused, P.TRIG triggers envelope. ● T1 sets the GATE time. RESULT : A trigger is used to GATE an envelope. Tangrams Manual...
- Page 20 = P2 SOURCE [3.9 3.10] ● PULSE 2 goes HIGH after the GATE IN goes LOW. RESULT : Because PULSE 2 is OR’d with the envelope’s GATE IN, it results in a retriggering and re-gating of the envelope. Tangrams Manual...
- Page 21 ● Envelope’s PULSE = P2 SOURCE [3.9 3.10] ● PULSE 2 goes HIGH after PULSE 1 completes. RESULT : T1 determines how long the start of the envelope is delayed, while T2 determines the GATE TIME for the envelope. Tangrams Manual...
