Quad Function & Trigger Source - 28HP


Introducing Sputnik Modular's new eurorack format modules. Influenced greatly by the west-coast synthesizer styles of Buchla and Serge. Extremely versitile module design!
The QUAD FUNCTION & TRIGGER SOURCE provides four independent or paired (quadrature mode) function generators.


  • ATTACK AND DECAY: 4 generators; The time range of each generator (.005 – 10 seconds) can be controlled via CV pulse input jacks for both attack and decay + control knobs; 3-mode switch per generator: CYCLE (LFO), TRANSIENT, SUSTAINED
  • OUTPUT: Each generator includes CV output + pulse output that generates a transient pulse at the end of the decay segment: if the generator is in CYCLE mode for instance, that cycle will repeat; QUADRATURE MODE SWITCH with green LED: when engaged, 1+2 (or 3+4) work in tandem + a shift of 90 degrees to each other. These pairs can then be linked creating complex ADSR envelopes.  Dedicated outputs for 1+2 and 3+4 as well as attenuator knobs for mixing channels.
