AnyBit Fever Dreams is back with something both nostalgic and brand new—F256K2 MIDI playback using custom C code. This time, he’s showing off how the Foenix F256K2 handles an old favorite: passport.mid, the classic MIDI tune that shipped with Windows back in the ’90s.
This isn’t just a sound demo. MIDI events are triggering the F256K2 case’s four addressable RGB LEDs, creating a synchronized light show that pulses along with the music. The result feels like a mini concert on a desktop, with visuals and audio stitched together by C code and silicon.
The F256K2 itself is the latest retro computer from Foenix Retro Systems, launched in 2025. Designed to offer an authentic 8/16-bit experience with modern I/O and polish, it handles MIDI files with ease and style. In this video, you’ll see that power in action—no emulation, just real-time playback and light feedback straight from the hardware.
The video is a short, effective proof of concept that blends retro sound with contemporary flair. If you’re into the Foenix line or interested in MIDI programming, this is worth a watch.
