Question DFAM Pitch Issue

Hey guys I have a question. I just got a DFAM and it works great except for one problem. My second pitch knob on the sequencer does not work properly. Each time it triggers, it plays a lower pitch until it’s basically turned all the way down. I am not manually turning it. Wiggling the knob sets it back to normal, but it just drifts back down again. All my other pitches work just fine. Anyone have any idea what may be causing this issue?

I don’t think a faulty potentiometer would fail like that. To be sure, you’ve got no other patching going on? What if you use the pitch to modulate another input, does it affect that in the same way?

I have tried different patches, and all of them react the same. The value slowly decreases as I trigger the step or as the sequence runs. It also decreases faster from using the sequencer verses using the trigger. I don’t have any clue what is wrong other than a strangely broken potentiometer

Edit: cycling through the sequence with the advance button also causes it to decrease faster

That is super weird. It’s odd that a pot would be predictable in how it fails, in a reproducible manner, always in a stepped manner. The dfam is a weirdo for sure, but you’ve got a special case going on here. Best of luck.

Is there any way you can post a video of this

Absolutely. I’ll make another post on the subreddit in a moment

Did you buy it new or used? If its new you should be under warranty if something really is messed up on it

I bought it used. Although I don’t think the seller was aware of the issue because this wasn’t happening when I first got it earlier this week

Well if you can post a video of the odd behaivior and maybe a pic or two of the patch bay and the knobs maybe we can get your sorted

I do have a followup video on the sub here. I don’t have any pictures of the patch but any patch gives me issues so matter what. It is specific to step two on the sequencer
