The joke is on him - I used to get this functionality for free way back in the day when (what I presume was) RF noise generated during the processing of ethernet traffic would get picked up by my cheap ISA sound card and sent to the speakers. I never built a sequencer out of it though.

Back in college, I would listen to AM radio while I worked on my computer. The radio would pick up electrical noise from the keyboard and the mechanical mouse. I wonder if this sounds anything like it.

TRS-80s were famous for bleeding over AM band. The entire AM band.

I read that the FCC really started cracking down on EM interference because early microcomputers were serious offenders. I'm guessing that's why there's a humongous RF shield inside my Amiga 1200.
