I just want to add that I apologize for coming off harsh....there is almost zero music composition software that can do what you are advertising here and not be complete shit at it. It isn't a dig on you. It is just that people think music analysis is a LOT simpler than it actually is and that harmonic analysis is super easy and obvious and we all just took year years of music theory at a 4 year music conservatory because counting to 12 is hard. If you don't get the counting to 12 joke it just proves my point.

Having said that, I'd love to help hack on some music software so if you aren't just trying to get easy money on blackbox software and actually care about music and software hit me up on discord: afreidah.

but seriously, if you want people to take a look post a github and write software we can run ourselves after clone. If I have to create some third party account so some dickhole has my info and then have to push my data (music) through their servers I honestly have very little interest because there is absolutely no reason why the software you described should be a fucking saas service instead of something I can run locally unless your motives have less to do with functionality and more to do with something else...

I love music and software, hit me up if you need/want help on the software or the music side.
