The radio feature said that one of the most prominent uses of this device was in kraftwerks "numbers" where it was applied to the snare drum sound. And finally I knew how they did it! Almost my entire electronic hobbyist musican live, I've tried to reproduve this cool drum sound. Listen: http://www.youtube.com/watch?v=6TlvNpIwTto&fmt=18
Anyone out there volunteering in building such a device? I guess that the "algorithm" could be found somewhere on the internet, because the internet knows everything and the truth

There's a VST called "ValhallaFreqEcho" (http://www.valhalladsp.com/plugins.html), though haven't used it alot, i guess it comes pretty close to the sound I'm looking for. But yet, it's no scope device

Thanks in adavance
