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..
and this one … as well, huh? yes, this is a synth and it feel like it might be the most interesting one so far..
just listen, even if you don’t understand italian, ..
here’s another approach the Synthaxe – but sounds like anything you already know, huh?
and yes, it is historic..
