last saturday my MacBook pro mid 2012 with high sierra 10.13.4 had audio drop out and freeze issues with what seem as if i was bring volume up and down... next day i update serato 2.2.2 and change preferences to recommended serato configurations. sunday's gig went fine. next saturday did fine too. last night it did same about 30 minutes into gig. audio would drop out then song would freeze. not sure if this is a board issue (I'm on ddjsx 1) or computer issue. these issues happened prior to updates. also as i change songs you seems to write tags again... after running my board for several hours prior to gigs everything was fine. when i plugged up for gig i noticed all my blue played tags were erased. i didn't adjust the gray/blue tags for it to do that.
