For the November Skratchpad in LA, John Beez came through with his truly amazing "Fretless Fader". Basically this takes a DJ/Turntablist from doing rhythm sounds and whatnot with scratches and other tricks to be able to actually play notes on a musical scale using just a turntable and his very special DJ mixer. Check out this John Beez interview for a more detailed explanation.
Below is the video I shot from the night he came to Skratchpad including some video of him sessioning with other top LA DJ's.
Here's some other videos of John Beez getting down with his invention including a video of him jamming with Greyboy on two Fretless Faders!
