The soundtrack of DungeonOS was created using the original sound chip of the Sega Genesis using the Mega MIDI Synthesizer by Aidan Lawrence and other synths that contain old console chips. We don't use digital VSTs, only hardware synths for the true analog feel!

We’re a small, family-run team. I take care of the programming, and my dad produces all the music and sound effects using a studio stacked with hundreds of hardware synthesizers.
