Pitch lock in scratchlive (SL1)

With my scratchlive when I pitch up or down anything more than about -6 with pitchlock on there is a noticeable degradation in the quality of the sound reproduction.

Is this a common thing?

If so, is it something overcome with SL3?

A guy I play with uses traktor scratch and advises he gets no noticeable degradation in sound

Trying to flip a few 130 bpm tunes at 116 without it sounding crap

All pitch lock features degrade the sound, it is a fact of the system. The Serato one is one of the best. Getting the SL3 will not help as it is the software side, not hardware side.
Pitch lock tends to work well up to 3% difference, any more and you will hear it. I think your mate is not listening fully, try to listen to Traktor yourself with the same files, i bet you find the same thing.

The whole concept of pitch lock/key correct is fucked. Computer programs have a difficult enough time just changing pitch like a turntable, but when they try to correct for key too it's a nightmare. Trust me, any time you are using that shit you are degrading your sound quality. If you start isolating sounds (like in production) you'll notice the degradation even with slight key/pitch changes. One of the points behind the controller one was so that you could accurately pitch the samples right off of the vinyl without any degradation to the sound quality. The only way to get it right without some serious computing power is to pitch directly off the vinyl, using your turntable.

Now, a lot of people don't give a fuck and use shitty lossy MP3s that sound like shit anyway so this might not be a concern to a lot of people. But if you care about the quality of your end product don't use that feature.

It's perfectly normal for Scratch Live. You shouldn't touch the keylock in Scratch Live as it's a horrible low quality timestretch-algorithm. The Traktor dude doesn't notice it that much, because Traktor has one of the better stretch-algorithms of dvs(if not best in any dj app, but it's ofcourse also heavier on cpu). In the following test between Torq, Ableton, Traktor and Searto on DJTechTools you can clearly hear the difference: http://www.djtechtoo...ableton-live-8/

Traktor's algorithm may be better, but any key-lock algorythm eats the dynamics of the spectrum and punch on the kicks, so if avoidable, don't use it when playing on a good soundsystem, no matter what software you're using..

wicked, thanks for that. it made harmonic mixing so easy. i have it switched on all the time, unless i'm purposely switching it off to get a harmonic blend.

meh.


again thanks, though.
