Hey,

playing from either of my vestax pdx2000 the on screen pitch keeps going from 0.0% to +0.3% and back again..

..i assume this is to do with the decks themselves as opposed to ssl.

Surely thats not normal and is there anything that i could do to remedy it or is it just a feature of the decks?

and it only goes +ve? not back down to -.3% as well?
tim 12:33 PM - 26 June, 2005
yup,

0.0%, +0.1%, +0.2%, +0.3%, +0.2%, +0.1%, 0.0% ....

could be your pitch slider is out of whack... tried finely adjusting it into the negative slightly?

tim, which version of the control vinyls are you using? And if CV01, do you have drift compensation on?
DJ Hondai 5:58 AM - 27 June, 2005
I'm using CV02 on my 3 months old Technics 1210 MK5 and even I have a little pitch drift with the latest 1.4 preview release:

with Pitch Reset on: 0.0% , -0.1% , 0.0% ....

with Pitch Reset off, but the slider centered at 0%:
0.0% , -0.1% , -0.2%, -0.1% , 0.0% ....

... although the control signal strength is coming in perfect

consider the time elapsed (doh!) which gives us 15ms/(7min*(60sec/min))=15ms/420sec=0.003571% pitch shift, which is... not much :-))

...is about the graph here playthatfunkymusic.de(detailed).gif <-click. So if you experience pitch drift, it is definitly a problem of your setup, either your turntables or cables etc. On my system I have a very very little pitch shift of 0.003571% after 7 minutes playtime! I think this comes very close to the natural wow+flutter of technics 1200 decks (check my post here scratchlive.net <-click).

how old is your vinyl?

SSL calculates that value by how much of the control signal it can read right? so if it can't read a part of it and all of a sudden it gets to a part it can read (say .1% ahead) it has to "jump" ahead, so it treats it like you're very minutely scratching.
tim 1:31 PM - 27 June, 2005
hmm, well i have quartz lock on so that shouldn't affect it..

and i'm using week and a half old cv02's without drift comp.

i've read in other threads about people complaing about Vestax's build quality and such, could that be an issue?
DJ Hondai 4:58 PM - 27 June, 2005
Yeah! In my case it's just the wow. pressing the record a little bit in different directions is followed by a little drifting. That doesn't matter, 'cause I can now set the record to a perfect position with no drifting at all.

Thanks!

Yes... very much so.
djwaz 7:42 AM - 22 August, 2005
I get this too, I only bought SSL 3 days ago, and when I play any track, the pitch wavers around around the same range as mentioned above. Not just 0%, but any pitch I set it to. I'm using CV02's.
I have New-ish Technics 1200Mk5's and new Shure Whitelabels. I don't have the drift comp on either. Any ideas?

Cheers

DJ Hondai 12:11 PM - 22 August, 2005
I have this problem too, but it seems there is a problem with the wow of the control records.

Try move the record in different directions and play again and if it changes it's behaviour, than the hole of the record is not perfectly centered or a bit too big...

What is your noise threshold setting?

My noise treshhold is set to -24db - the signal quality varies between 90 - 100 % and often there is a pitch fluctuation of 0,3 % also when I presse pitch reset on my Technics 1210 MK5, both the M77-4 and the tables are just 3 months old.

In my case it really depends on how the control record i placed on the deck - the holes give a little space to move the record in any direction - so giving the record little snaps from the side while playing with pitch fluctuation resolves the problem, but that snap also affects the playback, so this is no solution in long term.
djwaz 8:32 AM - 23 August, 2005
My noise threshold is -24dB as well.

Shaun W 6:37 PM - 23 August, 2005
Are you using calibrating the threshold setting while the needle is on the record with the platter stopped?
djwaz 4:06 PM - 25 August, 2005
surely am :-)

Unplug your turntable's RCA cables from the SL 1 inputs and then click the estimate button, what noise threshold setting to you get now?
djwaz 8:54 AM - 31 August, 2005
When I unplug the TT's, the noise threshold goes back to -72 when i hit the estimate button.. it doesn't matter what the threshold setting is when the TT's are plugged in, the pitch still fluctuates.

Are you using relative or absolute mode?

How much of a pitch fluctuation are you getting?
djwaz 5:31 AM - 2 September, 2005
using absolute mode, geting around .4% around whatever i set it too, so if I set it to +4.3, it'll go around 4.1 up to 4.5. Doesn't seem to audibly affect the tracks though, I can hold a long mix with no problems...
citizen0 2:03 PM - 30 December, 2005
Im very concerned about these pitch fluctuations, i have just brought serato , i have mk5 technics and using a ibook g4 8oomhz 640m ram. as i am a house dj i like to have long mixs so
its a real problem

Im getting a clear control signal and are using tbrand new cvo2s,

the pitch jumps are similar to the above, when i switch it into internal mode there isnt any flucuations, and it happens with all tracks

is this the known issue that rane is bringing a plug in to fix, and/or is there anything i can do in the mean time?

using 1.4 but thinkiing of trying 1.3

any more ideas solutions
nik39 4:07 PM - 30 December, 2005
If you're tt is in good shape you shouldnt get any pitch flux, the pitch offset after 7 min is 5ms, thats very very little.

This has nothing to do with the Serato's software or with Rane's hardware, it has everything to do with your turntables. Wow and flutter is present in all turntables... if it is actually affects your mixes, then your tables will need servicing (fluctuations from 0.0 - 0.3 are quite normal).
joshua 7:06 PM - 31 December, 2005
one thing i noticed is i got a brand new set of control records and was getting pitch flux on one side, the a side i think.
control records are warped, and that does affect the pitch in my experience.
check for that, that is probably the culprit.
if it is, try the other side and see if it trax better.
not gonna go in to great detail about straightening warped records b/c i've never really done it, but there are ways to do that.
just a thought, i had something similiar happen to me on the last batch i bought...

i know my vestax pdx 2000 does the same thing... not even noticeable for me tho, mixes just great. Im geussing its prolly just the tables.
