Hi. I see You use Kemper with DVP3.I just new Kemper user and ordered DVP3 for volume. And I am in trouble get it work.I connected "pedal 3" with one TRS cable to DVP port "EXP". Kemper does not show it out and does not show calibration -> does not manage volume. I used same cable and port and connected my Missio. If Mission is connected by both ((TRS to first --> port 4 and TS second to port 4) it works as volume + swich. I see cable in Ok and port is Ok. Do I need connect DVP3 differently or do I need use TS or do differently in settings. As well option, that DVP is invalid. . Can You assist?
