he SPUTNIK QUAD FUNCTION & TRIGGER SOURCE provides four independent or paired (quadrature mode) CV function generators for creating complex envelopes. Each generator can be triggered by an external pulse, a sustained gate (for ASR response), and is also able to selfcycle (for looping AD/AR or LFO-like shapes). Attack and decay times are controllable via CV or control knobs and each stage ranges in length from 0.05 to 10 seconds. Each section has a CV output and an end-of-cycle pulse output. Each pair of channels (1+2, 3+4) also features an output jack for an OR logic gate that allows for complex envelope combinations with the help of a control knob. Finally, quadrature mode allows each channel pair to be synchronized 90° out of phase with the duty cycle of its pair (i.e. channel 2 will begin its cycle when channel 1 starts its attack phase). Two slide switches (A/B and C/D) on a back on a module give a possibility to select the maximum envelope voltage level 0-5V or 0-8V.
