mt32-pi VS ostep-projects

I have just seen https://github.com/dwhinham/mt32-pi but it doesn't seem as easy to play with and well-documented as the other software I've used.

Cool system. I'd see if you can get a hold of a Roland MT-32 type synth. If your sound card has a daughterboard connector (it does, top right corner) you can get a Serdaco Wavetable board which would let you have generalMIDI output. An external MT-32 or a mt32-pi will also greatly improve your music output.

Regardless the best option is a MT32-pi solution. https://github.com/dwhinham/mt32-pi/wiki/Custom-hardware

I think MT-32 and SC-55, at least, are wildly overpriced for what they are from a music perspective, thanks to the retro gaming bubble. If you want to mess around with one, I would recommend checking out mt32-pi. In addition to the extremely limited MT-32 sound palette, it can also load soundfonts, which really opens things up a lot.

Check out Mini-Dexed and MT32-Pi. I use both and they're great. They are built on the bare-metal "circle" platform, so they don't run on top of linux (so no faffing about with JACK routing, etc.).

its a CJMCU 5102 DAC Board, which is one of the supported soundcards. You can use the internal headphone jack of the Pi as well, however it only supports 12bit PWM audio there, which is usable but has a lot of artifacts and I would not recommend therefore

You can turn a Raspberry Pi into a Yamaha DX7 using MiniDexed or a Roland MT-32 using mt32-pi (which also loads soundfonts via FluidSynth). I use both of these regularly. They're great. Both work with USB MIDI controllers with no additional hardware required and boot headlessly in a few seconds to work like a true instrument.

We were taught by Remzi (the author behind OSTEP). He was one of the best professors I have met at UW madison. Unfortunate that I had to drop though. Some of the projects we did were open source btw https://github.com/remzi-arpacidusseau/ostep-projects

So, run-tests.sh is being run and the source could be found here

The intro says they have projects throughout the book. This is the git they listed for them https://github.com/remzi-arpacidusseau/ostep-projects

OSTEP by Remzi and Andrea Arpaci-Dusseau is a great read for anybody interested in operating systems (https://github.com/remzi-arpacidusseau/ostep-projects). The projects in their class at the University of Wisconsin-Madison were mainly making edits to the xv6 OS

Projects

But since you've already read a few OS books, I suggest you move on to actually peeking under the hood and playing around with the concepts. OSTEP has problems at the end of each chapter you can check out. You can also try to hack into a real "toy" operation, like xv6 - check out the problems here.
