- Helps if the videos worked. It's from 2010!
- the bbc had an amazing command, ENVELOPE, which let you shape the amplitude envelope of a sound. you can read more about it here: https://www.muzines.co.uk/articles/keeping-us-posted/3303
as a kid i didn't understand much about how it worked; i mostly played around with it to get "laser" sound effects, but in retrospect it was astonishingly sophisticated for an 8 bit home computer. (which described a lot of the machine's capabilities!)
- Reading that comment I heard That Sound from the BBC Micro manual that they used to demonstrate the ENVELOPE command, the one with the rising and falling sequences of tones. I probably haven't typed that example in since I was in primary school, probably P7.
I'll probably have to go and find an emulator now, and try it out again.
