Thought I'd post this 'cos of Data's post in random music videos.

Proper synth geek.

Here are few more old synths 

This maybe slightly off topic but I thought it was interesting...

Check this out, mega synth made of 24 Gameboys and filters.

Amazing sound 

I like but it does seem like a lot of kit for 8 oscillators and 1 filter.

Wish I had the time, space and GF that would allow me to make stuff like that
