You could always e-mail Elliot and see what he thinks about it. I remember him being very friendly and approachable when he was developing the fader, always posting in forums and such.
I’m just going to keep posting turntablism routines I enjoy in this thread, if that’s cool.
Of particular note here is the technique he uses starting at 1:35, where he hooks his hand around both the upfader and crossfader, and staggers them to effectively double the cutting speed. It’s called the “Euro Scratch” and very few people do it. Also, starting at about 3:30, Prime starts to mix in mixer feedback. It’s a pretty crazy routine overall.
