Thanks for your reply synththeory.I know talking about loose knobs/pots is subjective. I was hoping a few users would have popped in with a "me too" or "not me", to build an average from.I'm including a short clip demonstrating what happens when grabbing the knob from different angles as if tweaking the setting. This applies to quite a few of the pots (1/4 - 1/3 maybe). I also notice that some of the LEDs are dim and appear almost off, and the pitch wheel sometimes drops registration of the up movement. Calibrating it fixes it for a while though.Here is the youtube vid: https://youtu.be/JqvGhxxRKJEI should have purchased it from a reputable place like Sweetwater. I bought it new on amazon, sold by a third party Unique Squared. Seems they have a 15% restocking fee even if item is completely broken, which is significant considering the 3k price tag.First foray into DSI and really bummed.
