Handling bipolar signals

[JoshuaACNewman]

This cable only gives monopolar signal. But you could split it so that the positive component of a bipolar signal (such as the 0:+2.5v of a Eurorack-standard signal) goes through one side and negative component ( 0:-2.5v) goes through another cable, wired backward. This doubles the amount of signal lost to forward voltage, though. Sending that signal to a box that properly forward biases the LEDs could solve that issue. Using a low forward voltage LED like a yellow or red will also increase the response around zero. Or, alternately, that box could DC offset the signal until it’s entirely positive.
