I’m the developer of FM Composer, a synthesis-based music creation tool, and I’d like to make Defold able to playback the songs created with this tool.
Hey there, I’m the guy who commented on your youtube clip, welcome!
So, turns out there’s no SDK. Defold uses cloud servers to build individual engines for the game developer once you start using native extensions. Not 100% sure how it works when developing your own NE’s, but I suppose the tutorial should be enough to get you started?
