Topic: Confused.. -0.00 & +0.00 pitch - Page: 1

This part of topic is old and might contain outdated or incorrect information

I've never asked but have always been curious of how VDJ has two 0.00 pitches in the increatment? I've never tested to see if anything changes when going from -0.00 to +0.00 pitch, but I hope not... Is there a way to fix this so it just shows 0.00 in the pitch windows when my slider is center like any CD player or turntable?

Any takers for an explanation of why there are two 0.00 pitch settings and does the pitch change when you go from -0.00 to +0.00?
 
Well, i think that it shows that because you would have to set your pitch very exactly to get 0.00. Maybe you have your pitch on -0.002 or +0.004... Nobody notices anyways. It's just VDJ being (a little bit to) precise. :)
 
No difference from what I see/hear. I guess it's for which way you are going up or down (+ or -).

C'mon guys... someone at VDJ must have a better answer. Thanks for your input but it'something else I'm sure...

No CD player or turntable in the world has a - & + 0.00 pitch. It should be just simply 0.00 then incretments up (+) and down (-).
 
My brother, ive asked questions like this before, (i think it was because some tracks start at -20,-30 seconds and others dont) and i think the answer/conclusion i came to was that nobody here seems to give a rats @ss... sad, but thats the vibe i got...
I know sh|t like this bugs me too...

It's exactly what VanStino said.

Internaly the pitch is devided to 8192 values (or some other number). And if the fine step is less than what can
be displayed, the percent will be below (-) or above (+) middle value. There's a funny part though, if you use
a pitch_reset function the software goes to -0.00, which is probably the issue of choosing the bit below middle
to represent the center pitch - if you have 2^n values, the middle value is always between the possible values:

eg.: 0 1 2 3 4 5 6 7 => the middle is between 3 and 4 ("3.5"), but you can only choose 3 or 4.

The solution would be very simple though, you'd just need to put a function that check the rounded value,
and if it's equal to zero it changes to (+).

If it bugs you guys, think of it that this way you can see the pitch has changed slightly.
 
Sorry to correct you... Vanstino didn't say exactly that!

When someone starts of a sentence with "I think" that's not the answer I am looking for when I have a question about a product I paid good money for(Sorry, typical answer in a user forum). If I didn't care about precision I would not have asked this question to start with either!! Excuse my english but if I'm correct in understanding your theory that there is possibly over 8192 values in the pitch speed there's no way that VDJ can't have a 0.00 without the + or - 0.00 when I use it at 12% setting?

HERE IS WHY I ASK
If there is a difference in speed betwen -0.00 and +0.00 and I have the same song loaded in each player and 1 deck is at -0.00 and the other at +0.00 and I want to create a long "Phase Shift" effect using my CDJs in quartz lock mode I'll have to keep adjusting a deck in the software to compensate?? This never happened to me using only my 2 CDJs in Quartz lock mode without VDJ because CDJs don't have a - and +0.00, it's only 0.00...

Can someone asnwer me from VDJ team? 3 questions...

1) is there a difference in speed between -0.00 and +0.00 at the 12% range?
2) If so what is the amout difference between -0.00 and +0.00 at 12% range?
3) Is there any way to fix the xml file in the skin to not show a - or + and just show 0.00 in center position?

To answer your question, I just did a quick test (wanted to make sure myself):

I used 3 files:
- original wav file coded @ 44.1kHz 16 bit
- recording one of the original file from VDJ playback in same mode right after
opening the software and loading the track on deck (display +0.00)
- recording two of the original file from VDJ playback after loading the track
and pressing the pitch_reset button (which displays -0.00)

Than merged original + Rec1 and original + Rec2 on their exact starting point
with the editor, having one of the tracks phase inversed.

What should happen if the pitch was the same is total cancelation of signal in
both cases. What happend is original + Rec1 gives this result, while original
+ Rec2 creates phasing effect (cone filtering) meaning:

Yes, there is a difference between +0.00 and -0.00 value, where software's
0 pitch is shifted in relation to original song's pitch for exactly 1/4096 or 0.000244%
if you wish (a lot less if 12% range setting also changes the percision). It's just that
display shows you only 2 digits...

But if you want precision, you can create a shortcut with function pitch
and value +1, thus you move up/down with the fines resolution possible.
Pressing pitch_reset and than this pitch+1 will get you back to the original
pitch of the song.

Hope you will get an answer from the team though.

Regards
 
^^^Great answer there

Also I use timecode cds with cdj200s. I lie to make extreamely long mixes. With the 0.02 pitch resolution on the cdjs this is great but what I would like to do would be to say increase the pitch accuracy again by assigning to the keyboard, a 0.01 pitch increment.

Whenever I tried this it works but as there is not enough steps available with the value of 1, so it still increases the pitch by a 0.025 when I want only 0.01

Any solutions?
 
OMG, im all for understanding ones surroundings but come on.......
"oh no it shows a minus or positive sign".

can you tell me when the last time you mixed a pair of 3 hour long tracks and wanted to spend the duration in the toilet?

If its not actually affecting anything other than your curiosity who cares??? youve spent your 'good money' and demand that the character disappears?
 
Well I care.... and I haven't demanded anything either!!

When I purchased my 1st 1200s and my 1st CDJ-500IIs & CDJ-1000MKIIIs and my Rolex watch and my Bose-alarm clock and my topline laptop and my many topline computers, ect, I expect to have percision when I spend good money for any product including software. If I didn't want percision or quality I would have purchased Gem Sound CD players, a $5 digital watch, Technics belt drive turntables, a $1 store alarm clock, a low end Acer laptop and a Pentium 1 computer, etc and Dj'd with winamp or something in that quality "for lack of knowing low end DJ software". AND, yes, I'm curious to know why VDJ has two levels of 0.00 as there is no such thing in life... Please tell me I'm wrong and I'll shut up! Sorry, no such thing as -0.00 and +0.00 so yes VDJ team should fix it as others are saying there is a difference in the speed and correct the digital display in all the skins!!!

If you feel you need to, make your own skin that shows pitch to ± .001%............most of the world is perfectly happy with ± .01

"Sorry, no such thing as -0.00 and +0.00"
'-0.001' can be shown to 2 DP '-0.00'. easy. and showing + or - 0.00 is the definition of precision. If you reset the pitch on both decks they will play at the same pitch. simple

besides in nature, nothing is absolute
 
I use an xponent to control my mixing or the CDJ-1000s so resetting through the software or keyboard seems outdated... the least amount of doing too many functiions lets me focus on my crowd, mixing, effects and music selection. Anyhow, I would still like to hear from a Teamer of Atomix why the 0.00 can't be just 0.00. You can find all the excuses/reasons in the world to go against what I'm saying but the fact remains... there is no need for two 0.00s as a center position
 
I don't know if this is relevant at all but many digital number representations account for a -0 and a +0. For instance if they are using a float to keep track of the pitch there would be a +0 and a -0. As for the test previously posted, that could just be due to rounding.
 
I'm not trying to be rude or anything, but after reading this thread, I have to ask myself, who f'n cares?

Who gives a f#ck what you guys think!!

Do you put this remark in every topic that you don't agree with or feel it's a waste of your time reading.

I'd still like to hear from a "REAL" Atomix teamer as to why the 0.00 works in this manner and know if there is a way to set the digital display to only show 0.00... as per my original comments.
