MT32-Pi DIY synthesizer: bare metal 80s nostalgia

This week, let's build and take a look at the #MT32 PI, another "bare metal" synthesizer running on #RaspberryPi. This is an emulator for the late #80s Roland MT-32 sound module, which was used by a lot of games for their sound track. The MT-32 PI can also load soundfonts, so you can use it as a ROMpler in your setup. Table of contents:

Some bands / artists I've been following for a long time are (among others) Massive Attack, Pink Floyd, Pet Shop Boys, Archive, A-Ha, Yes, Porcupine Tree, John Mellencamp, Jean-Michel Jarre, Metallica, Peter Gabriel and Perturbator. So my music will kind of sound like those (without ever reaching the greatness of those artists, of course). :-)
