hi folks,
i own a sc live 4 and a mixstream pro, also some pooneer gear like djm 450, xdj-xz, xdj-rx2
i experience on both - the sc and the mixstream - a lag of about 6-10ms when using the faders for fast cutting like 1/8 notes. feels a bit like using a controller on serato with a buffersize more than 512
is there a possibility to solve this problem?
There might be , in the future, although thereās not a human way of āfeelingā 6msās, so Iād start looking at more likely options.
Some more feature packed (more expensive) models have menu options for fader curve and fader cut-in.
Itās quite likely that such options were not included in the more budget conscious models.
There of course, needs to be a good chunk of āmissingā menu options and features between top end and cost-effective models, otherwise no one would buy the top end models if all the same features featured on the cheap models
hm.
if i compare the sc live 4 to a xdj rx2 - they are quite similar priced.
and the rx2 does not have such a lag.
speaking of the 6ms - i am djing since 30 years now - be sure, i am inhuman enough to feel these 6ms.
Oh well - check the menus/manual for any fader contour, fader curve or possibly cut-in options.
Thatās about it.
I wouldnāt call Ā£500 difference āquite similar pricedā, I mean if you were buying a car or house then it could be, but not an Ā£1100/Ā£1600 DJ gear item.
Bear in mind that one is 2 channel and the other is 4, meaning the economies of scale are further pushed apart, more components to build a cheaper model = cheaper components.
As Pasha said, perhaps the more demanding DJ should look at more demanding gear for their use, there is a reason the DJM-S7 is so expensive.
cāmon
a controller priced 1000 bucks and above should not have such a lag.
speaking of the lag - if the fader is closed, there is a lag of 6ms befor the sound goes off. you can not change this by changing the contour.
btw. why are you trying to tell me, it is a question of money if something works like it should?
man, even the cheapest mixer from numark is cutting without a lag.
If all the 1000 Buck item did was fade and crossfade then Iād agree; it should have a fraction of a millisecond ā¦ā¦ If thatās all it does, it should as you say, for 1000bucks , do it perfectly.
But some might view things as , thankfully the primes do more of a 999 Buck āother thingsā and ā¦. Oh yeah ā¦. there are faders which are fast enough for -most- users.
Different users need different specs. Scratchers need little in terms of library functions, menus, album art, samplers, and everything from page 9 of the manual to the back page, but they need ānippyā fader response (again check for fader curve/contour settings offered in the models youāve got - there are primes in the range that might suit your needs (those 3.52ms responses 
) more than what the SC lives offer.
Youāve got the right ecosystem but may have needed to have gone hands on for final selection within the range. Every model has its own pluses and minuses.
The cheapest mixer from Numark is a dedicated scratch mixer and has an innofader installed. It also has vastly less features and components than the SC Live 4.
Perhaps turntablism wasnāt top of the priority list when designing a 4 channel budget friendly standalone DJ controller.
I donāt know what the benchmark is for lag free crossfader cutting on standalone DJ controllers. But you picked 2 of the absolute cheapest on the market, surely you can see this comes with some caveats on performance?
What percentage of people buying these devices are going to be using them for scratching? 2%? 5%? 10%?
