Kate Bush talked about it – and using it in Experiment IV („the sound that kills some1“) with Fairlights etc. – well – if it’s rom sounds or something in here..? don’t know but might be plus filtering or/and controlling synths..
here’s a demo in italian..
he tells about controlling the filter which also are nice in the 1st video, in’nt? sounds analog, thoo..
