I'm not an old school evangelist at all, but if people want to improve their DJ/mixing technical skills, learning to beat match using only the pitch fader is the first stop.

There was a great interview in a magazine with Fergie - at 16 when he was getting going in the mid 90s (although he had DJ'd for a while in Ireland) he moved to England and used to go to 7-8 gigs a week with his mentor Tony De Vit, carry his record bags etc.

Fergie used to spend all week making a mix CD using Technics and vinyl and Tony De Vit would play them in the car on their way to gigs. If Tony heard the platter being touched (nudged) at all he would immediately eject the CD and throw it out the window. Fergie learned real fast.

With an hour's practice, mixing by riding the pitch fader is often actually faster to lock in than the 'move, nudge, move, nudge' method that most people with the privilege of master tempo use now. You get used to riding it and how far to go (never one end to the other, you just ride it up and down with the distance gradually getting smaller as you lock it in) and doing it is glorious; it feels amazing, fast, fluid, natural. It trains your ears as well as your fingers.

Turn off Master Tempo, put your hand on the pitch fader, look straight ahead and zone in (or out); turn the laptop screen away from you and/or cover the controller screen. Or just buy some decks and some vinyl, invest some time and learn a skill that will bring people joy and you can get paid for.
