Quad Function & Trigger Source

Sputnik Modular

Quad function generator a la Buchla 281.

SPUTNIK QUAD FUNCTION & TRIGGER SOURCE provides four independent or paired (quadrature mode) function generators for creating complex envelopes.
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.

These merchants probably sell this module. Huh?
