Dual signal transmutator

SIGNOS is an incredibly versatile dual channel utility and waveshaper module for processing both CV and audio signals in just 8HP.

Both X and Y channels feature a classic / unipolar VCA with separate normal and inverted outputs, a polarizer / four-quadrant multiplier / bipolar VCA, a -5V to +5V manual offset voltage that gets summed with their respective channel's bipolar VCA outputs and a red/green LED indicator for this output. The offset voltage can be used on its own if no main input signal is present.

X and Y sums of their bipolar VCAs output + offset (referred as X+offset & Y+offset from now on) are then feeded to the following logic and waveshaper circuits: an AND analog logic gate that outputs the minimum of X+offset and Y+offset; an OR analog logic gate that outputs the maximum of X+offset and Y+offset; a MOD waveshaper that represents the mathematical modulo operation as an analog CV modulator and waveshaper, with both X+offset and Y+offset affecting different parts of this circuit; and a SHIFT waveshaper that was originally designed to pitch-shift sawtooth waves up an octave, but that can also do interesting wave-mangling to all kinds of signals.

All of the above are just the module’s building blocks, only the tip of the iceberg of what SIGNOS can do. It naturally lends itself to feedback patching techniques within itself and/or other modules, complex waveshaping, external signal processing and more. The limits of what SIGNOS can do are completely up to you.

As all of our modules, it features reverse-polarity power protection.
