A baremetal kernel that turns a Raspberry Pi 3 or later into a Roland MT-32 emulator and SoundFont-based General MIDI synthesizer, built on Circle, Munt, and FluidSynth. It boots in seconds with no OS, providing low-latency MIDI audio for vintage PCs and FPGA retro setups.

Use cases

• emulate a Roland MT-32 for classic MS-DOS games
• turn a Raspberry Pi into a dedicated MIDI sound module
• play General MIDI or Roland GS music with SoundFonts
• add low-latency MIDI audio to a MiSTer FPGA setup
• use a Raspberry Pi as a USB or GPIO MIDI synthesizer

When to choose

• you need authentic MT-32 or GM/GS sound for retro gaming on real vintage hardware or FPGA
• you want a dedicated, fast-booting synthesizer without Linux audio complexity
• you have a Pi 3/4/Zero 2 W and an I²S DAC or MIDI interface

When to avoid

• you need active development or new features - the maintainer has stopped releasing updates
• you need high-quality audio from the Pi's PWM headphone jack
• you have a Pi 1 or original Pi Zero, which are too slow
