How can I convert music (in MP3 or MIDI form) into a noteblock song in Minecraft on Mac?

I am trying to possibly use a few music files, which are all MP3s and to convert them into noteblock form in minecraft (either the physical structure OR a .nbs file, which Note Block Studio can export to and can be used in a variety of noteblock plugins for servers). However, I’m running Mac, and it seems like Noteblock Studio is only for Windows. (Link: https://www.stuffbydavid.com/mcnbs)

I’ve tried manually transposing the music by hand (placing the noteblocks and the redstoning by hand), but it’s proven to be really tedious and I need a more efficient way to convert music into noteblock form. Are there any viable options for what I’m trying to do? Is there some sort of Mac version of NBS, or is there an alternative program/conversion method?
