4 x 4 Crossbar Modulation Matrix
Three variations of a 4x4 switching matrix intended to be used for switching modulation sources or audio signals.
The first is a true switch with a toggle for each crosspoint. Each toggle also has an input which will invert the state of the toggle when it is > 0. Then second features knobs which allow a variable amount or signal at each crosspoint. The third is also variable level but is an input only with no manual adjustment. The signal at each cross point is switched or multiplied by the control input then they are added across the row to the output. The modules are 4 x 4 to save screen space, but could easily be expanded if necessary.
