I'm not in a huge hurry, but one of two things (Either one should work, though the later would help me out more and depending on your price if you decide to do it, possibly both):
- Macrotune for 64 Bit Windows (The current version keeps freezing on my Win10 computer).
- A javascript based Macrotune-like extension for a game engine (basically, I want the player to be able to craft their own songs mid-battle as well as being able to use pre-made songs).
