Pagan Opus Editor

It's esoteric and it's *probably* not for you, but give it a try if you have ever thought:
1. Notation should be expressed in numerals, specifically in radix-12 numerals
2. Sharps and flats are arbitrary
3. Rhythms that aren't divisible by 2 should be more legible
4. You'd just prefer to work in spreadsheets wherever possible

Export to MIDI or import and reorchestrate an existing midi file.
Absolute & Relative notes, input a difference up or down from the previous note.
Easy polyrhythms.
Link repeated sections for efficiency's sake.
It's a song editor. Use it to make songs.
