FM Synthesis

That Mega Drive and Japanese PC sound, LatelyBase, AdLib, gnarly metallic harmonics, icy/crystally caves…

I really don't have my head around FM synth yet, but I'd like to get one to learn about it. These're my notes on different machines. A lot unfortunately require dicking about in menus, but I'll probably be doing any patch editing in a DAW anyway. Kinda need to combine with reverb and/or other effects I think.
