Divided into two sections...
1. Mixing Technique
2. Scratching technique
My favourites are:
Mixing - Cuts, Fades and using EQ to slight of hand a sound out of view, extremely quick mixes that no-one notices. Reversing vinly by hand and keeping it going at the right tempo by hand while mixing with the other one!
Scratching - Scribble, Oribt and click flare... crabbings fun but hurts after a bit and gets boring. vocal cuts and re-arranging vocal samples.
Stuff i use not very often: spinbacks, stops
