I don't know if you keep in touch with music production nowdays but algorithmic compositions are on the rise. From modular synths containing modules that generate pieces to external sequencers doing euclidean rhythms and the like. Great stuff.
Old video game consoles. Right now almost exclusively NES, but I really want to start messing around with the SNES's SPC at some point. That thing looks way too interesting :D
I have an edrum kit that i play, but for th first songs we just used a MIDI keyboard. We are doing everything in the box. Happy to share more if you want.
Was a bit in a hurry. Our former drummer is our studio engineer. We record everything ourselves and mix at home. We have a good but basic setup that creates a good result. Happy to talk more about it.
