I’ve intermittently had issues loading a track where the system seems like it’s frozen for 5-10 seconds. I haven’t been able to predictably recreate this but I’ve only had the issue with a couple of fairly old USB drives (haven’t had a problem with any SD cards) so my assumption is that the cause is a slow USB drive. Currently there doesn’t seem to be any visual indicator that would show the system is responsive but loading rather than non-responsive.
Similar programs’ features I’m thinking of are Ableton Live’s disc overload indicator or Traktor’s orange flashing status bar, just so that I can trust it’s still working and leave it alone for a few seconds and not instinctively make things worse by hitting buttons to figure out what’s going on.
