I’m a beginner. When I put a song into mAirlist I have always an error Access violation 012BA08F on mAirlist.exe Module. Read Of adress 00000000.
I try also to connect my DJ console Pioneer DDJ-SX on mAirlist, but when I want to change the driver the system returns always to the driver who is first mentioned. Thanks
Hi and welcome,
please take a look here to get a basic understanding of how mAirlist handles the Audio Routing. You probably not set the soundcard in the right part of the config… 
It’s written for v6 but you can transfer it to v7 easily:
