I made FantasySynth because making music for my games was very very very hard. DAWs felt like an uninspiring desk job and hardware was too limiting and unaffordable. In my almost 2 years of making FantasySynth and 7 years of Game Dev, I am just now starting to have fun with recording music and only have a fraction of the musical skills a lot of you have had for many years. I beg of you, plz make some ultra cool songs to show off what FantasySynth can do.
Not made with AI.
I enjoy solving problems and art, so I became a game dev, I won't let ai take what I love to do even if I'm slow.
