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.
To make setting the inversion point as easy as possible, the value can be set to specific notes using the notation A#4, C-1, Gb+3, etc. in addition to entering as a normal voltage value.
