I was finally able to chain my Maschine MK3 Mikro to my Boss DR-202. Since the MK3 Mikro dosent have MIDI jacks I used this adaptor

The Mk3 sounds fine thru my laptop and the Dr 202 sounds fine thru its headphones jack. But when I plug them into my Behringer Xenyx QX1002USB it sounds crackly and has no bass. The MK3 is going from the laptop headphones jack with a 3.5mm to 1/4" to the mixer. With the DR 202 I tried going from the headphones jack and the L and R line outs but both ways sounded the same. I tried changing the buffer size and sample rate but it didn't do much. I've ran both the MK3 and the DR-202 thur my mixer before and not had this problem. I know using the headphone jack isn't ideal, but I don't see any other options when it comes to my Mikro. Any thoughts on how to fix this? Thanks.
