Hiya!
I made some quick videos, I'm not sure if they're useful to anyone? Here's one on ring modulation: http://www.youtube.com/watch?v=qOLtd5STBbA And another demoing the A-106-5 and A-105 filters: http://www.youtube.com/watch?v=u6vT-ZfKG_E Pretty basic stuff, but hopefully useful to someone. :)
All the best,
Zoe.
