I know @t9999clint is working on WavePi, which will probably fulfill most of my needs. Still I wanted to experiment with more options. So in my quest for a Raspberry Pi 3B setup that can act as a Roland MT32 & SC-55 emulator I came across Patchbox OS.

I have a Hifiberry DAC+ADC hat and unfortunately had to break the realtime kernel on Patchbox OS to get hifiberry support with rpi-update. (Or does somebody know how to get realtime kernel working with Hifiberry?)

I got Munt, the MT32 emulator, running with shell and x binary, following this tutorial https://retropie.org.uk/forum/topic/12549/tut … lation-on-rpi-3

It's sort of a hit or miss with the jack and my limited knowledge of all things linux audio.

While the x binary did show me some “LCD” screen, nothing much was to be seen on it. So I want to try the Qt version.

But my limited knowledge of linux got me stranded building the mt32emu_qt binary. I basically installed Qt 5.7.1 (latest available via apt-get), IIC also had to install portaudio and changed one of the cmake parameters to -Dmunt_WITH_MT32EMU_QT:BOOL=ON but ran into problems 😦 Something like

1fatal error: QtWidgets/QAction: No such file or directory
2 #include <QtWidgets/QAction>

Hopefully someone can help me out?

I also saw somebody made a LV2 out of Munt https://linuxmusicians.com/viewtopic.php?t=12937
So I thought, maybe this can be added to MODEP. But I have no clue how to do that. And given that the lv2 github is rather old I wouldn’t know how to have it use the latest Munt 2.3.0.

Thanks for taking the time to read this and hopefully this can lead to have MT32 running on Patchbox OS and/or MODEP.
