Hi .Sorry about the late reply - I've been offline.
It looks like your interface is one stereo in and one stereo out..This isn't helpful . It would be better to have and extra output so to monitor your master buss ,while feeding your kp with a send buss .
I don't use software so I'm not the best person to answer this (

) but you could consider controlling your DAW with midi via the pad. Set up a reverb in the daw ,latch somesoftware controls to your kp touch screens x & y CC controls ..ie work out how to assign midi CCs to your software ,await input then swipe either vertical or horizontal to assign control of your pad for desired control like send or hpf. Then record this control info to your daw .
This may all sound too complicated if its new to you. But as far as straight audio of said daw through kp effects back to daw - I'm having trouble thinking of a way with your (nice but ) minimal interface.
Maybe someone else can chime in.
