Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/MiniDexed/commit/d59a74ff69240d17dbbaf72268133c3bc116b9b8
You should set ROOT_URL correctly, otherwise the web may not work correctly.
[Dexed](https://asb2m10.github.io/dexed/) is a FM synthesizer closely modeled on the famous DX7 by a well-known Japanese manufacturer. MiniDexed is a port to run it on a bare metal Raspberry Pi (without a Linux kernel or operating system). __This is a work in progress. Contributions are highly welcome.__
