A module that allows modification of the 1V/OCT control voltage used for notes, transposing them by octaves, semitones and quartertones with optional inversion of the control signal before transposition with CV-controlled switching of the inversion and transposition.
The inversion point can be controlled (useful for inverting envelopes around the sustain level) with a Learn button to set the level to the current input. Using gates to switch these modes can generate interesting harmonic variations. Using a number of these with voltage-controlled switches or sequential switches can generate interesting harmonic movement.
