Denon DJ MCX8000 firmware v2 — finally primed

A quick recap – the Denon DJ MCX8000 übertroller was released. We reviewed it, and bar some disappointment about only two standalone channels, we were very happy indeed. But storm clouds gathered, and swirled around the vortex of hurricane Engine Prime. MCX8000 owners were not happy, for they had been left out in the cold of Denon DJ’s new top tier VIP club. But now, after a period of beta testing, the MCX8000 V2 firmware is here, and with it comes the ability to read Engine Prime USB drives, and a slew of additions, improvements, and fixes. And there’s a supporting V1.2.1 release of Engine Prime. And it’s all free.

Obviously, there’s a press release:


Denon DJ’s MCX8000 is now “Primed” for Engine via its USB drives and gets performance and hardware upgrades for improved microphone/recording workflow and beatgrid/sync enhancements.

Cumberland RI, USA (September 12, 2018)—Denon DJ (, a leading manufacturer of premium DJ products and solutions, today announced that they have made a major update to their Engine Prime v1.2.1 software and firmware. This update now enables the MCX8000 controller to be feature enhanced with Denon DJ’s standard-setting Engine Prime music management software, giving DJ’s unprecedented control over their digital music. The MCX8000 will utilize Engine Prime optimized music libraries via its USB drives, and new performance and hardware features have also been added to the MCX8000 via its v2.0 firmware update. Improvements include microphone/recording workflow, beatgrid/sync and quantize enhancements, plus song browsing improvements.

In addition, Engine Prime itself has been improved, and this new version 1.2.1 has enhanced music library and track import features plus optimized playlist options, along with its newly-added MCX8000 database export support, giving the MCX8000 performance capabilities that are unmatched by virtually any controller currently available. Also, the Prime Series SC5000 and SC5000M media players can now be firmware-updated via a USB drive, without the direct use of a computer.

Denon DJ MCX8000 controller firmware v2 Engine Prime

All aboard Engine Prime

It took some time, a little persuading, and some straight calling out, but Denon DJ has finally delivered on their promise. It’s not just making the MCX8000 wrangle Engine Prime drives, but all the other gubbins that’s been included in this releases too.

We can only hope that this will be enough to placate those who felt wronged by Denon DJ. They have after all done it to keep their customers happy, and probably in part to extend the longevity of a controller that really hasn’t got many rungs to climb to be top of the food chain.

I imagine the next one to be a four deck standalone jobbie, with a big touch screen and probably a wealth of other stuff you think you need. But for now, the MCX8000 (can we call it Prime now?) sits pretty on the upper rungs of the DJ technology ladder. Be happy.

It’ll all be available on the Denon DJ site soon.
