为什么值得看
安全研究者完整逆向了 M-VAVE FM-1 口袋合成器的固件架构，识别出杰理 AC791N 芯片方案和 Dexed 衍生的六算子 FM 引擎，并公开了 OTA 升级协议的 USB-MIDI 抓包分析。对嵌入式 AI 音频设备和智能硬件供应链安全有直接参考价值。
编辑判断
杰理芯片在低端蓝牙音频设备市场占有率极高，但公开技术文档极少，这次逆向填补了 AC791N/WL82 系列的架构空白。pi32v2 CPU 和 XIP flash 的内存布局对做 TinyML 或端侧音频 AI 的团队有移植参考意义。
作者刻意把替换固件放在独立分支，主仓库只留分析，这种合规操作值得国内 IoT 安全研究者借鉴——避免 DMCA 风险的同时保留技术价值。如果你在做智能硬件出海或供应链审计，这套 OTA 抓包方法论可以直接复用。

核心争论：低价硬件+开源生态是否比自研STM32方案更具价值
For context, this is a $65-$80 synthesizer that's been pretty popular for its cheap price tag, and there have been a bunch of third party firmwares being released to make it even more friendly and feature-packed than it already is out of the box. There's quite a bit of discussion in the subreddit: h
For those that haven't been following along, a TON of custom firmwares have shown up for the M-VAVE FM-1, a roughly ~$70 synth. BaudGirl's VA is probably the biggest right now: https://baudgirl.com/work/FM-1+VA But there's also https://github.com/hugelton/Felu
They are SO FUN, seriously. Best $180 I spent (because I bought THREE M-VAVE's!!)! .. But, it also has to be pointed out to the HN hoipolloi: these firmwares run in web-based emulators too!!!! So you don't have to blow $60 to join this music tech revolution ..
