I think I subconsciously left the other stuff in so I could listen to it and get irritated. I like to piss myself off, and it pisses me off that I do.
Made with a ZX Spectrum triggering a Casio SK-1. Well, it wasn't actually triggering it. More like flashing and beeping at it. But I couldn't use the beeps because I would be disqualified. It did flash and beep rather well though.
Now I forget how I used the sampler...
(Changed the description because the other was old and funky.)
