Oddly specific question that I need help with

I’m trying to find a deconstruction of hardware (essentially an advanced instrumental, with each instrument and vocal separated)

I cannot for the life of me find one

It doesn’t necessarily need to be the original, I’m fine with it being MIDI even if not ideal, but the one time I got kinda close the website (musescore) decided I needed to pay a subscription fee

I don’t really want to disclose what I need it for cause idk if I’m gonna actually do it but I want to at least set it up first
