When I open DJ Pro AI and load my first song, the wave form preview bar displays as expected. When I load a song in another deck the wave form preview stays blank - if I load another song on the same deck as I loaded the first song, the wave form preview of the first song still remains. The main scrolling wave forms do appear for each song that is load and are coloured - suggesting that DJ has processed them. Any ideas? Using Mac Air with m1 chip.
