yeah i do what communicator says above, only i find that there is a slight lag when you adjust the pitch, so if i am feeling impatient i sometimes give the platters a push with finger (makes the mixing of the overall set a bit rough but for me this is ok cus i am not capable of doing surgically clean mixes anyways)
for italo i find that you have less room for pitch, especially speeding up, it sounds wack if you pitch adjust too much...
other than that i find it helpful to cheat abit using bpm counters, you can just peek at it get ballpark bpm, and decide if the difference is too much to pull it off.
in fact i still bpm check the 1st record of every set to put my u-boat in the right bearings.
5, 3, 6 or 100 platenspelers, fuck it!
