When sorting by song key, in this case using open key, the tracks don’t sort at 12m or 1m from top to bottom or vise versa. For some reason 1m loads in the middle of the list, runs down to 8m then from the top it pick back I’m up from 9m. Also this feature should stay active when leaving a list to cut down on steps needed to further sort tracks.
It’s because the Primes offer so many ways of displaying the music keys.
If you think of the true music keys A, B, C , etc, Prime will always sort songs by TRUE music keys regardless of whatever other “cosmetic” labels other harmonic mixing protocols might label the true keys as, eg open format, 12A, half-banana etc
