For hands off background Ambient mixes, I have a particular criteria - full track length, 10 second normal crossfade, no sync.
But these settings are not suitable for every playlist or occasion. For example the dinner party, the kitchen disco, when stop/start cue points are incorporated, track lengths are constricted, funky crossfading is linked to bar length.
I would like to make AutoMix presets to use on any playlist, or maybe presets can be recalled along with specific playlists.
