I think it would be cool to add a stem player feature (similar to how kanye's stem player works). I doubt AI stem isolation is possible for the ipod, but it would be cool to import your own stems and play with them stem player-style, especially since the ipod has the clickwheel with the 4 buttons, maybe even lower each stem with the clickwheel? I hope someone picks this up because a lot of people would love to play with this sort of feature and also not spend 200$ on a stem player when we have perfectly working ipods with a lot more storage.
I don’t know about the difficulty or skills required to complete this, but that’s a pretty good idea.
I’m not sure if it would be that difficult because realistically, if some one could code a plugin to section the music into 4 areas for the 4 buttons (Bass and sub bass, Lower mids, Higher mids, and Trebles and tsts cymbal noises) and code those sections to a comfortable UI, that’s basically plug-in done. In a way this has already been made with bass and treble, if you play a song and then long press on select and go to sound settings, then bass or treble settings which is pretty neat. But back to your question, I COULD TRY to do something but I don’t have much time on my hands because of exams and some stuff in my personal life I kinda lost the motivation to do anything for a while and I feel like crap, so I think that it’s best for someone else to do it.
