Despite suffering from the ugliest interface I've ever seen (Orange, yellow and lime green? Together?) Neuromixer VDrum is a very cool thing. Load up a folder full of video and/or sound samples, then trigger them from the xoxox-style step sequencer. It comes with a perfect starter pack of old Kung Fu movie clips (here) which rapidly thread together into Wu-Tang/Depth Charge beats. I would post one of my two-bar creations, but I couldn't work out the recording function. At the moment the sequencer only has quarter note resolution, which makes those beats pretty clunky, but it's really designed for DJs playing video clips. It's a v0.1 Beta but seems reasonably stable. Currently XP only, with an OSX version imminent. (Thanks Mikey!)
