Howdy all,
After not playing with it for a good couple of months, I turned on my maple and to my surprise, the dac's output is inverted!! My meter even suggests it's outputting a negative voltage, even, which I didn't think was possible. My synthesizer suggests the same, as its response seems backwards. I measure the voltage coming off of my pots, and they're outputting the usual 0-3.3v, but as that voltage rises, the output moves the other direction. What's happening?!?!

okay...so it's not the maple..hehe. But! It seems the culprit is my jack, but how?! I'm not a super noob or anything, so this is pretty frustrating. I'll switch out another jack and see if it persists, but can anyone explain to me how wiring a jack wrong can result in an inverted signal?

should've waited on the "i'm not a noob" comment, looks like I had signals going to the ground pins and vice versa on these jacks...seems like maybe I've always used these particular jacks wrong, but polarity had yet to be an issue (rarely cv, always audio). But there you go!
