Sigil

Sigil is an Analog Function Generator in small format with voltage-controlled Rise and Fall stages. It features a voltage-controlled Cycle Function to toggle the output Envelope to an LFO/VCO and vice-versa          and a continuous Shape control that morphs both the Rise and Fall slopes from exponential to linear to logarithmic, ranging from really snappy to very slow slope settings. Sigil also includes an End of Cycle Trigger Output, useful to chain subsequent envelopes. Input can work as a Trigger or a Slew Input, depending  on the position of the jumper in the back of the module. A handy Attenuverter sets the Output voltage range from -10V to +10V. Sigil has been carefully calibrated to deliver musical slopes throughout and packs all the essential features of a Function Generator into just 4hp!
