mt32-pi

Little bit shallow article. Raspberry 3/4/5 are in a different league than RP2040. Newest Zynthian kits are updated for Pi5. There is also a big difference between using Linux (e.g. Zynthian) and running barebones (e.g. Minidexed, MT32-pi, probably some proprietary offerings). https://shop.zynthian.org/ https://github.com/probonopd/MiniDexed https://github.com/dwhinham/mt32-pi

At least two of the hats https://github.com/dwhinham/mt32-pi/wiki/I%C2%B2S-DACs look like they are currently for sale. And I didn’t check all of them.

For people interested in this, there are several open source projects which turn Raspberry Pis into a MIDI synthesizers: MiniDexed: 8 DX7 Tone Generators - https://github.com/probonopd/MiniDexed - https://www.youtube.com/watch?v=Z3t94ceMHJo MT32-Pi: Roland MT-32 emulator - https://github.com/dwhinham/mt32-pi - https://www.youtube.com/watch?v=vaSD_wbzJRw Optionally, buy a PCM5102/PCM5122 or ES9018K2M I2S DAC to improve the output sound quality since the DAC built into the Raspberry Pi is not that great: https://raspberrypi.stackexchange.com/questions/76188/how-to...

Alternatively, if you are interested in making or playing back music, one idea is to turn the Raspberry Pi into a MIDI synthesizer: MiniDexed: 8 DX7 Tone Generators - https://github.com/probonopd/MiniDexed - https://www.youtube.com/watch?v=Z3t94ceMHJo MT32-Pi: Roland MT-32 emulator - https://github.com/dwhinham/mt32-pi - https://www.youtube.com/watch?v=vaSD_wbzJRw Optionally, buy a PCM5102/PCM5122 or ES9018K2M I2S DAC to improve the output sound quality: https://raspberrypi.stackexchange.com/questions/76188/how-to...

Pretty cool. Seems like this project was built on the Microdexed [1] code, which is a port of Dexed to run on a teensy. It uses circle [2] as a bare-metal basis on the pi, which was also used by mt-32pi [3] to run a sample-based synth that can emulate the roland mt-32.

Does studying toy operating systems teach strictly more, or just different skills, than studying bare-metal embedded frameworks like https://github.com/rsta2/circle (which powers https://github.com/dwhinham/mt32-pi, unlike Zynthian which is Linux-based (https://zynthian.org/#software))? I dropped out of uni before completing my OS course, and I planned to look into mt32-pi, but sadly struggled with hardware and software setup (game MIDIs wouldn't play right, and in terms of sound design, all the good MT-32 patch editors are for obsolete platforms and many are gone from the Internet).
