I wrote the product specification for the MCX8000 so I think I understand what you are asking for 
What you are both referring to is a Serato DJ feature and not Engine. The MCX8000 (standalone) only allows you to slide the grid, the adjust button is used to set the quantize value size.
We are planning to bring flexible, variable beat grids to Engine and the Prime Series in a future update.
That is also planned as new feature in future. That ability will likely come at same time as flexible beat grids.
We’re also working on improving our beat detection algorithm to prevent the need to adjust offset beat grids and incorrect BPM.
Axcindently erased my question for the beattempoadjust so here it is, answered as above! The suspension is real.
I think it is important to make further steps towards prime devices being self contained. I was disappointed to learn, that I need a computer to manage my engine library. I was hoping for a true stand-alone experience. So flexible and variable beat grids on the players is something I’m really looking forward to 
It’s asrounding that ‘prime’ only has 5 letters in it and it’s an important branding to get out there and into peoples heads yet some peeps are already not bothering to type the R, the I, the M or the E.
If we like this system, let’s keep the Prime name in the mentions yay!!!
Then you will be happy to see Crate/Playlist management directly on the devices 
absolutely 
Ohhhhhhhhh yes! 
Thanks for the answers
Then I´ll just hope youl´ll find some other way to make it work somehow like that serato/vdj-feature.
Can you also shed some light on the activation of pre-defined loops, @JWiLL - will this work the old way again, where you can activate the loops before pressing play? (P4 and SC5000)
Best regards Kim
I hope you doing this bpm algorithm improvement with various types of mainstream tracks. I think that’s the one EP struggles with. Its alright with house and edm stuff as there is usually well defined beat intros. 4 x 4
If you want maybe we can send tracks over for you to test with.
can you use serato & a usb at the same time? For example let’s say serato playing on channel 2 and I want to use the USB Channel 1 at the same time. Like for DJ change over
Logic says no. Serato will only be working if Prime4 is in controller mode, like the SC’s.
I was hoping it was different then my SC5000 I was ready to go buy the prime 4. that’s a deal breaker for me
I wanted to be like the mcx8000 where you can use serato on one channel and play music from a USB on a different channel at the same time. I don’t need it to a just the beat grid just to be able to use my laptop and the USB at the same time
Don’t take my word for it. Let’s wait for an official answer.
You’re right it’s going to work in controller mode just hoping they can do something different like theMCX8000
Do we have a complete list of features to compare the Prime 4 to the Sc5000 + X1800 kit? Surely there’s a perk to the now $2,999 kit versus the single unit for nearly half price, right? I have not yet found a list to see for myself yet.
I ask because in other product lines, like Roland Aira, they release a “flagship” DJ808 and soon after their “mid level” Dj505 comes out with twice the # of drum voices per kit… So the owners of the nicer box end up with a 4-voice drum box and the cheaper units have double. I would just like to verify that Denon didn’t add cooler, newer features to the Prime4 & forget that the SC/X combo should be “flagship” feature-rich still.
As soon as you get one of these …
In a world where people are asking for more, more, more info On-screen, every few hours, it seems, you just follow your anti-everyone else response mode. 
Why is this logical? I would say this could be handled by the internal software on a per deck basis. But only Denon choose to restrict it to a special controller mode.
How cool would it be if on this device you could play stand alone on channels 1 and 2, while having your Serato (or Traktor or Virtual DJ) software ready at your fingertips on channels 3 and 4?
The same goes for the SC5000, only there you want to have standalone on deck A, while you have your DJ software ond deck B.
This sounds almost as a perfect setup for me: best of both worlds.
To make this complete Denon could add Ableton link to sync all connected software and devices (don’t forget the Akai Force as well!!!) together.
All of the above sounds more logical to me.
Sometimes information that is not needed can be distracting. I find it impossible to ignore the BPM and phase display when matching beats acoustically 
.
Hiding different pieces of information on the Prime devices would require a complex setup procedure. Each and everyone will have different needs and wishes. Probably not many people would use this feature either. So I doubt Denon will ever implement something like this. But for me such a feature would make sense 
. In fact, I have taped of buttons on the SC5000 which I don’t use during a set.
