Sputnik Modular Quad Function and Trigger Source

The QUAD FUNCTION & TRIGGER SOURCE provides four independent or paired (quadrature mode) function generators.



  • 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


  • 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.
