Function Generator

4 HP Eurorack module

Analog function generator with voltage-controlled rise and fall stages, usable as an envelope or a cycling LFO/VCO.

Features

Rise/Fall Shape— Continuously morphs both rise and fall curves from exponential through linear (about noon) to logarithmic.
Rise Time— Sets the rise (attack) time of the function.
Fall Time— Sets the fall (decay) time of the function.
Rise CV Input— CV input for modulating the rise (attack) time; approximately ±5 V range.
Fall CV Input— CV input for modulating the fall (decay) time; approximately ±5 V range.
Trigger/Slew Input— Trigger input by default; with the rear jumper set to slew mode, accepts audio signals and gates for slew/envelope processing.
Signal Output— Bipolar ±10 V function output, usable as an envelope/LFO control voltage or VCO-rate audio signal.
End of Cycle Output— 0–10 V trigger output that goes high at the end of the cycle/fall stage.
Output Attenuverter— Attenuates and inverts the Signal Output, setting its range from −10 V to +10 V.
Signal Output Indicator— Bipolar LED indicating the polarity and level of the Signal Output.
Cycle CV Input— CV input that toggles Cycle on or off with incoming positive voltages; approximately ±5 V range.
End of Cycle Indicator— LED indicating the End of Cycle trigger.
Cycle— Locks the envelope into retriggering via its end-of-cycle signal, turning it into an LFO or VCO.
