how does pitch adjustment work?

i've got a technics 1200 mk2, what do the increments on the pitch adjustment mean?

anyone know how many bpm, semitones or cents the record playing goes up or down when you adjust the pitch?

is there a calculator/converter or something that can help me out?

thanks.

just doin some research, pitch adjust 3% = 1 semitone? is this correct?

Easy mathematics

E.g. if you have a beat with 95 bpm and you pitch it up 1 % its 95 plus 0,95 = 95,95 bpm

If u want to calculate a lot:

pitch [new track]= 100*(bpm [playing track) : bpm [new track] - 1)
 
Exact. But don't rely only on the mathematics, ur ear will tell you if you have matched exactly 2 tracks.

Btw there's also a chart how much percent you need to pitch a note up, but i don't know where.
 
One half step for every six percent.

D at 0.0 = D

D at +6.0 = D#

D at -6.0 = Db

And yes, 45 rpm is like +35.0 at 33 rpm. So if you want to speed up the track to 45, you need to pitch up by +1% to stay at a natural note (which would be 3 whole steps higher in pitch).
 
you also need to remember to set your pitch by the strobe. The markings on the pitch control on a modern SL1200 dont correspond to the amount of pitch adjustment.

Older SL1200's from the 1980s are more accurate - but still off.

If you want to adjust the range of the pitch to make it closer to the markings - then there is a pot which you can adjust under the plastic cover, underneath the platter.

Thats the first thing you should get adjusted when you buy them - preferably by the dealer who you bought them from. They are almost always out of alignment when they come from the factory.

EXCELLENT point! If you don't have a true 0.0 setting, then all the math is meaningless. You can adjust the pot yourself, you'll need a multimeter, or you can just twist it in quarter turns and do some trial and error.
