(I am very new to music production so maybe I am missing something really easy)
I have a problem, when I connect my Digitakt to my audio interface with the left and right jacks, every note after a low note sounds distorted. For example, directly after a kick the open hat sounds metallic. When I use overbridge I don’t have this problem and everything sounds clear. Is the problem in my (quite cheap) cables or maybe my audio interface (U-Phoria UMC404HD )?.
You said that you tried with headphones on? Was that outside the headphone jack?
Have you tried the output jacks with headphones or plugging it in to another interface? I would double check the interface, is there any indication that the settings could be causing distortion?
