LDX #0 - Magitek Factory / Devil's Lab - Final Fantasy 6 modular synth cover
I've always liked the Magitek Factory theme from Final Fantasy 6, it has that relentless industrial beat, but main melody is in more or less major and it still has a bit unsettling atmosphere.
I found bugs in my Arduino code for synth module that does the bassline, so in middle of recording there was some code rewriting sessions, fits the theme well. And PT2399-based delay module sounds like a failing and starting engine when the delay time is set way too low.
