# microfreak-emu: rehosting Arturia MicroFreak firmware in Renode

> microfreak-emu rehosts Arturia MicroFreak firmware 5.0.0.2084 in Renode with models for STM32 peripherals and audio output. Its research documents firmware addresses, stored formats and the SysEx message exchange, while the harness supports boot checks, MIDI-driven differential runs and preset rendering.
