If you're looking forward to the return of Dr Who, you might enjoy This post from Pete Swarbrick on the Analogue Heaven mailing list: "As some of you in the UK know, my day-job involves the supply and tech support of cameras and associated kit to the film and TV industry.On my latest visit to the new Dr Who production I spotted the guy doing the Dalek voices hidden round the back with a good old Coles lip-mic and a small rack of audio stuff.
On further inspection it turned out that the majority of the rack was not in use, the only active bit was a mic amp/compressor which was feeding a Moog MF102 Ring mod hanging round the side.
I know there has been a debate about the original Dalek voices being true ring mod or just a fast-gated VCA but I thought maybe one or two of you here might like to know how it's being done this time around. Can't remember any settings apart from square LFO though..."
