This module is part of the ADMX system.
It blends together two ADMX signals in a proportion determined by the control voltage fed to the A->B CV input.
When the CV is 0 V then the output is the same as the signal fed to A IN. When the CV is 5 V then the output is the same as the signal fed to B IN.
Intermediate control voltages cross fade between the A and B signals. Simple linear interpolation is used for the Pan, Tilt, Aux 1, Aux 2, Aux 3 and Aux 4 values, however the Hue, Saturation and Brightness values are converted to RGB color space before the interpolation is done and the result is then converted back to HSB.
Although this module is related to the ADMX Combine module, it provides explicit control over how the signals combine. Also the color mixing done by ADMX Combine and the ADD IN function of ADMX Color is additive so the result can be brighter than either input color whereas this module interpolates between the colors so the result can’t be brighter than the brightest of the inputs.
