Shit! So that's what the slidey thing on the right hand side is for. This is gonna make things so much easier now. I used to just try and pick two records that were the same speed. I always wondered how those guys managed to do it.
But seriously, I've been trying the "ride the pitch" thing recently, but only at home, cuz like Matt said, you gotta be really comfortable to do it at a club, etc. It takes me longer to line the records up, but by practicing it, it gets better with time, as one would expect.
But for the most part, I use both methods to fix a record that is out of line when I am in the middle of mixing it in. Becuase pushing/pulling it only solves your situation temporarily. The records will eventually go off again. So I'll do the push/pull thing and then as soon as I do that, I just slightly nudge the pitch control so that I won't have to push/pull it again.
And one more thing ... I don't ever "pull" a record to slow it down. I just pinch the little centre piece to slow down the platter. I find it to give you greater control, and be more accurate once you get used too. It's just like pinching a nipple.
Cheers ... Ian
