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 expensive, limiting, and bulky. In my almost 2 years of making FantasySynth and 7 years of Game Dev, I forgot to get the music making skill lol. I beg of you, plz make some ultra cool songs to show off what FantasySynth can do.
