To obtain the result of the LFO starting at -5 volts instead of +5, when LFO trigger mode is set to note on, thus giving the opposite effect of what normally occurs doesn’t work when I resolder the wires on my patch cable as was previously posted to one of my questions. I was wondering if I was missing something. I simply unsoldered the one end (both wires) and soldered them back on opposite to what they were. When I test the cable with a ammeter/voltmeter thing it show the voltage fluctuating above and below zero but when I use the cable and patch out of the LFO hole in my VX 351 back to the voyager into the volume, or filter inputs no sound occurs. Did I miss something? Has someone actually done this not just in theory?
back to the voyager into the volume
Isn’t volume always an unipolar input?
What should happen to the volume, if 0V means silence and +5V full volume?
I’m not sure what you mean by unipolar. If the LFO starts at +5 which means full volume , or full filter etc etc then I want the opposite effect. For the LFO to start at 0 volts, or -5volts. Whatever. In other words, filter/volume closed when note is pressed, and then filter opens up to full. Basically exactly the opposite of what normally happens.
You need to use a reversing attenuator to do what you are trying or see if there is a pot mapping option to invert the signal for your routing.

That’s what I was referring to. Doesn’t work people. I guess an attenuator is next on the list. I’m currently waiting for the phaser in the mail. Thanks all for the help.
