One of my favorite blogs, Create Digital Music, ran a piece on NIN doing a rehearsal for Echoplex.
It's neat to see the Lemur, a touch screen MIDI controller, used live by the drummer. Overall the song structure is relatively simple but it is amazing how well they keep together. Notice the dude manning their monitoring setup full time and the in ear monitors 8-)?
I need to get a hold of an old touchscreen PC and see if I can convert it into a Linux MIDI controller with Open Sound Control and maybe some custom Java. It's sad because I had something perfect for the task a few years ago, an IBM Industrial panel PC, basically a laptop in a bulletproof magnesium case with touchscreen :-(.
