CV Protection

CV protection is something you have to be aware of when doing CV related mods. If your CV device outputs too high a voltage, or even a negative voltage, then the out-of-bounds input might just hose your x0xb0x.

Here are a few ideas on how to deal with the problem.

Protection from Negative CV

VerifyMe: Just connect the cathode of a diode between the CV in and the rest of your circuit. This should shunt any negative voltage to ground before affecting the rest of your ciruit.

            ^  Diode
            |
           --- GND

Protection from Extreme Positive CV

VerifyMe: Use a ZenirDiode, set up like the above, but instead of shunting it to ground. See http://www.musicfromouterspace.com/analogsynth/SOUNDLABMINISYNTH/SoundLabMods.html#PROTECTCVINPUTS for more information
