Thank you so much for your detailed reply! I can't believe that was your first attempt at writing a soundtrack! You're super talented! :)
Is Furnace your main tracker to create your music? Is this it? https://github.com/tildearrow/furnace
I'm a music newbie, so I'll need to experiment to discover my own process. I was thinking about using OpenMPT to import midi songs that I'll create with FL Studio Mobile.
Thanks for being a hUGE inspiration! Sorry not sorry for the pun. hahaha...
