The mics got some essential attention, relating to the automatic microphone gate for disco and wedding use.
routing the mic to headphones might be included In some future update.
They only added the other two streaming services which were initially indicated in the console features. It doesn’t seem like a gift to me.
Indeed. They have aligned the analysis of the Engine OS BPM to Engine Prime (as was also the case with the version number).
It would be nice to know if the various BUGs reported on this forum have been corrected, as some defects have not been listed from the list of changes. For example, @PKtheDJ, the lack of the artist’s name in the horizontal view, has it been fixed?
My disappointment comes only from the long wait (8 months) to then have these few improvements for Prime 4: gate microphone, recorded microphone, BPM detection as Engine Prime.
It does make me wonder if it will be another 8 months until the next update, to just add Beatsource Link.
Firstly all thank you for your comments, and of course all your suggestions that you’ve made.
I’d like to clarify a few things;
1 - Your voice and suggestions are important and we listen to them! But not every request that’s made will make it into an update, the team review all of them and they help shape how we will push the products and OS forward.
2 - Of those suggestions that are put on the roadmap, not will all make it into the next update. Some are simple to implement, most are not and take months of development and testing. Please be patient as it’s imperative we get the updates out as reliable as possible by testing thoroughly (thank you beta testers!).
3 - Denon DJ is one of the only product manufacturers that runs it’s own operating system and is able to offer new features to their customers, this may not be every month but how many other media players and standalone DJ units are out there that offer any substantial updates that given you new features?
I appreciate that some core features have been requested for a long time, I can assure you that the team are fully aware and these are being worked on. That being said, they will not get out there until they are good enough for the public to use.
Remember Engine OS is ever evolving, those of you who have had one of our products for sometime now would have seen some major updates and new creative tools to enhance your DJ workflow, and more are coming.
Thank you.

As I’ve said (just) On another thread, I think this is probably one of the best updates to the primes since their launch.
And the fact that that yesterday’s update benefits not just one “lucky” unit, but actually benefits, seven models (7!) makes this even more of an achievement. It benefits People who own the :
5000 5000m 6000 6000m 4 2 Go
And the 1800 got its firmware updated last month (month before? Sorry, lockdown merging of months 
)
And Engine Prime software got a significant update at about the same time too.
I think we are starting to see incredible benefits from Denon DJ now having that firmware/software development office in New Zealand now.
It’s all very well, although somewhat immature, by stamping feet and rowdily waving rattles in the air for selfishly pointing out that “your” feature hasn’t been looked at (yet?) but we have all been blessed by the software and firmware efforts of the denon team over the last few months.
Other makers would have had us buying whole new models to get such massive boost-ups from the machines that we bought.

Guys, the Preview thing has been commented many times before from Denon officials, and the reason why its not implemented yet.
They have to figure out how to route the Preview to one of the unused channels. It has shown to be a bit more dificult as its a 4 channel unit.
Ok I will wait for the next update since after months this is kinda disappointing. No track preview (since they added it on P2 , Go and Engine they realized it’s a very useful feature) No bpm editing on the unit itself. No better effects section ( on P4 compared to Pioneer effects sound like ■■■■). I love this unit but there are some unforgivable lacks. Fingers crossed for the next update.

I agree I think this is a brilliant release. The BPM analysis and downbeat on tidal, soundcloud and beatport is solid. Really good job Denon DJ and Inmusic.

but sorry but when I load a track already analyzed nothing happens! I don’t see any difference from before! how can traces be analyzed again with the new algorithm?
i know it’s not in the release notes but reverb / hall echo seem a bit more useable for me? maybe it’s the track i was playing but i could manage dubbing it out a bit 
I need to check the echo effect, as there were two issues for me.
One is that turning the feedback down doesn’t stop the feedback. You still get multiple repeats, even when it’s right down.
Second is that wet/dry doesn’t seem to be fully wet. Turning it to dry is OK (no echo) but turning to wet, you can still hear the dry sound - which implies that half way is not 50/50.
Hi everybody. with this update is possible to listen microphone in headset?
After a few hours… despitecmy update pbs, this version is very good. Thanks for Soundcloud and Beatport.
4 points for next release please :
-
is it possible to put back (or by choice) the old fonts on the small lcd screens ?
-
16 bars/32 bars on flanger/phaser
-
Track preview on the two main channels (if not possible on all 4 channels)
-
more settings on the 4 sweep fx
Thanks that’s a good job. We were waiting for it ! 
Love the new bootup with this upgrade
Green became blue, yes nice indeed.

after update can’t find the Tidal link anymore
if you click on the high left volume Icon it shows two more streaming services (beatport and soundcloud) but tidal not there anymore
@djveleno Not on the unit (currently). You can re-analyze in Engine Prime on Windows or Mac:
To re-analyze a track:
- In the track list, click a track you want to re-analyze. To select multiple tracks, press and hold Ctrl (Windows) or cmd (macOS) and click each one. You can also press and hold Shift to select all tracks from the currently selected one to the one you click.
- Right-click the track(s) and select Re-analyze Tracks in the menu that appears.
Or alternatively, but most likely very less desirable, you can erase the Engine Prime folder on the drive and start from scratch with the new algorithm. I would currently recommend re-analyzing the drive with Engine Prime
Ditto, takes about 6 hours to reanalyse my library of 73k tracks.
Much faster than Serato. I think Engine Prime is optimized to take full advantage of multi core processors.
So if you have one of them i7 or i9 Intel CPU you will be cooking with rocket fuel
