The Lowdown

The iDJ Pro is an impressive step up in terms of hardware quality and features, and coupled with a tight and clever integration with the djay app, it delivers a sturdy and attractive package. This means the iDJ Pro is an desirable proposition for budding DJs who have been trying out their DJ potential on an iPad but want to make the leap into a fully immersive, more rewarding and physical set-up.

First Impressions / Setting up

The hardware

The iDJ Pro shares the same design bloodline as other more expensive DJ products like the Numark Mixdeck Quad or the Numark NS6. The touch-sensitive jog wheels are similar to those on other recent Numark controllers (albeit without any flashing LEDs), so their generous size and response makes scratching a breeze.

Numark iDJ Pro iPad
Your iPad provides, without a doubt, the best screen on any DJ control device ever – better by far even than Pioneer’s top-of-the-range CDJ2000nexus, also launched this last week…

The curved edges immediately make the unit feel feel friendly, while the brushed metal surface gives a quality feel to the build, although overall the quality is “good consumer” rather than “professional”. The colour scheme of ice blue and fresh green LEDs give the iDJ Pro a visually futuristic style.

Having rotary volume controls instead of faders for each deck will no doubt have some experienced DJs spluttering, as most mixers and controllers feature volume slider controls positioned close together for a reason (so you can fade down both tracks with one hand). Admittedly, I was taken aback too at first – but I have to admit that after seeing the green LEDs light up as you turn the dials it was hard not to smile and picture yourself commanding a spaceship!

Inputs, outputs and fittings
The iDJ Pro has a pair of balanced XLR outputs as well as stereo RCA output connectors at the rear of the unit. A Kensington security lock connector is also present, so you could lock the iDJ Pro to the booth ensuring that no-one reaches over during the night and walks off with it. I guess it wouldn’t stop them whipping your iPad out though…

The rear of the unit features a snap-shut hinged section which allows the iPad to be slotted (gently) into the central part of the iDJ Pro. The iPad is placed into the unit with the “Home” button furthest away from you (at the top); this is so the iPad can be hooked into the unit via the short 30-pin connector cable. When the hinged section is shut, the 30pin connector cable is hidden inside the unit. If you’re using an iPad 2 or third generation iPad then some Velcro adapters ensure for a tight, snug fit into the iDJ Pro. I was initially worried about ventilation, however Numark has designed the unit to ensure sufficient circulation around the iPad during use.

Simple yet effective and thoughtfully positioned inputs for Mic and Aux – useful for mobile set-ups.

Apple often tinkers with dimensions and specifications between the regular versions of its hardware; for example, it’s rumoured that the company will be phasing out the 30-pin connector. However Numark assures us that should that happen, adapters will be available.

The different fitting options and “upside down” arrangement plus the promised availability of cable adaptors should therefore mean that forthcoming iPad models will fit into the unit and be connected up without issue. Of course it’s always going to be a bit of a question mark when new hardware from one manufacturer is incorporated into older hardware from another, but it’s good to see that Numark has at least thought about this and done all it can to future-proof the unit.

The front panel provides a microphone input with simple gain and tone control alongside stereo auxiliary inputs (also with a gain control). The auxiliary input could be used for adding a further sound source (like a drum machine or sampler) into the mix; however without an EQ or crossfader assign option here it would maybe too risky for some. I would be inclined to use it as a means for a quick and effortless DJ switchover.

There are two different-sized headphone sockets with a master/cue mix and volume control. It’s worth noting here that you do not need a stereo splitter cable for use with the iDJ Pro; all audio routing is all handled within the unit. While both headphones and master outputs are technically currently in mono due to a limitation of iOS5, it is worth remembering that iOS6 (expected on September 21) could be bringing stereo cueing and stereo master outputs using multiroute audio.

iDJ Pro hardware software integration
The integration of hardware and software tries to bring out the best of both; for instance, you select FX on the screen, but then use the top-middle controls in this picture to make your changes.

A clever feature of the iDJ Pro is that firmware updates will be delivered to the unit via the docked iPad, either through the djay app or possibly a dedicated app from Numark. So should this happen, Numark can remotely update your unit for you in a hassle-free way to take advantage of this and any other iOS developments.

All of the buttons, dials, sliders and both jog wheels on the surface of the iDJ Pro are sending Midi messages to the iPad via the 30-pin connector cable. The cable also sends audio back to the iDJ Pro, and charges the iPad at the same time – no worrying about battery life during a gig!

Because the controls are sending Midi messages it means that the iDJ Pro could be used by other DJ apps; in fact, we understand the makers of some have already approached Numark with this in mind. The main consideration for the app developers would be to ensure a useful portrait interface design of their software (most DJ software runs best in landscape mode) and that their iDJ Pro versions make best use of the controls available.

The software

As it stands though, Numark has developed the iDJ Pro in close partnership with Algoriddim and in particular that company’s djay software, to ensure the iDJ Pro is paired neatly to the functionality offered in the djay app. In order for the iDJ Pro unit to excel, the app taking centrestage needs to make the best use of available space, which is why Algoriddim has redesigned its DJ interface into a portrait view (it flips automatically). However, this is much more than just a simple orientation adjustment.

Redesigned djay interface with the iDJ Pro
The djay app gets redesigned with added functionality for use with the iDJ Pro.

In order to best spread functions out across the touchscreen window and the hardware, Algoriddim has altered what is visible on the screen: The pop-up window that’s used to access features like loops, cues, FX and EQ that exists in “standard” versions of the software has been removed. EQing is taken care of via the high, mid and low rotary controls at the top of the iDJ Pro, so no need to duplicate effort on the iPad view either. And the cue functionality (main cue plus three additional hot cues) is all handled via the cue buttons at the lower deck part of the iDJ Pro.

So what is the screen used for? Well, the top of the screen shows waveforms (not parallel, though) and track playback detail, the “note” icon next to the BPM display being how you’ll trigger the keylock function. Underneath this are three buttons for each deck (as well as the Settings button):

  • FX – There is a drop-down list showing five effects that you can choose from. The chosen effect will be used when you press the “FX” button on the iDJ Pro (situated alongside the loop controls). With the button pressed the effect will be continuous until the button is pressed for a second time. During this period you can adjust a parameter of the effect with the rotary dial above the FX button
  • Loop – This button shows the current loop length which can be adjusted via the loop buttons on the iDJ Pro
  • Waveform – Pressing this button will display a permanent zoomed in view of the waveform during playback. This is something that has been requested as a feature on the djay app for some time now, so good to see it here

The centre of the screen is dedicated to the deck view with a swipe gain control in the middle. I found it tricky to adjust the gain with any great reliance or accuracy, mainly because the spot you need to press is so small and seemed to be slow to respond to movement. The lower section of the screen is specifically for FX, whether it’s an X-Y pad or one of the six instant FX buttons. The redesigned interface means some of these controls (such as the FX pads and buttons) are larger and much more useable than on standard versions of the software.

In Use

The “Load” buttons above the crossfader can be used in conjunction with the central rotary dial to display the Music Library screen and select the next track to play; alternatively you can use the track load button within the app. Once the track is loaded, your focus moves to the cue buttons at the lower part of the deck. You can delete previously stored cue points by pressing “shift” and the corresponding cue button.

Numark iDJ Pro crossfader
The Numark iDJ Pro crossfader feels nice in use, but there’s no obvious way of replacing it without returning to the manufacturer should it wear out.

The pitch slider is positioned at the top of the unit leaving the pitch bend and sync button at the lower part. This separation of the pitch controls took a little getting used to, but without it the unit would either be wider or those large jogwheels would have to be sacrificed.

The crossfader has no adjustment controls on the iDJ Pro, however within the djay app you can set it up for scratching (by enabling the “Crossfader cutting mode”) or reverse it (via the Midi section of the settings).

I like to know that I can replace my crossfader as it’s usually the first thing to go in my mixers, because it’s the most used item on the hardware. With the iDJ Pro, you’d probably have to visit Numark for a replacement to be fitted if it had to be done, as there’s no obvious user way of making this change.

Once your cue points and pitch have been set, your track is ready to play. You can get creative through use of the six loop buttons at the top of each deck; these correspond directly to the manual and auto loop functionality in the djay app. Alternatively, if you press the Shift button and the loop buttons you trigger the “Bounce Loop” functionality.

As we’ve mentioned already, you can have a continuous effect applied in conjunction with the X-Y FX pad on the touchscreen. If this isn’t enough, there is also a high pass / low pass filter rotary dial for each deck which can be used at the same time for some interesting overall effects. The audio quality is perfectly acceptable if not world-shaking, albeit currently in mono only. (Most club DJs, whether they know it or not, are playing in mono as most club PA systems are set up that way, so this isn’t as big an issue as you may think.)

Overall, the iDJ Pro plus djay software makes for a well spaced out, fun and – once you get over some of the idiosyncracies of the set-up – effective DJing experience, with some intriguing benefits that could only have been brought to the table by combining the iPad’s screen and storage with some of the more conventional controls of the Numark hardware.


Numark was first off the blocks with its earlier iDJ Live, providing a simple if gimmicky controller for iOS devices. Although the iDJ Live raised eyebrows among the experienced DJ community, it succeeded in bringing familiar tactile DJ controls to a mass-market at a low price point.

The iDJ Pro is an impressive step up in terms of hardware quality and features, and coupled with a tight and clever integration with the djay app, it delivers a sturdy and attractive package. This means the iDJ Pro is an desirable proposition for budding DJs who have been trying out their DJ potential on an iPad but want to make the leap into a fully immersive, more rewarding and physical set-up. At the moment the iDJ Pro is set up for use with djay by Algoriddim, however it seems it also works with djay’s sister app for video mixing, vjay. Unfortunately there is no portrait mode for the vjay app but I expect this may come in the future.

Also, because the iDJ Pro is dealing with Midi messages between the hardware and the iPad, any DJ app with Midi functionality could possibly map to those controls. The success of alternative DJ apps with the iDJ Pro will depend heavily on how well the app uses the portrait mode, the correlation between controls and app functions, as well as audio quality.

Numark iDJ Pro
For innovation alone, Numark deserves credit for the iDJ Pro. It is, in short, a hoot to use and if you like gadgets – well, I need say no more.

For innovation alone, Numark deserves credit for the iDJ Pro. It is, in short, a hoot to use and if you like gadgets – well, I need say no more. But Algoriddim has also done an excellent job of adapting its already great software to bring out the best in the combination, minimising control duplication and bringing to the fore functions that make great use of the big, tactile screen.

Overall, the combination of hardware and software is an exciting one, and notwithstanding concerns over future compatibility with hardware (and the fact that it’s not possible to tilt the iPad once fitted; I’d have liked to be able to do that to make viewing easier), it really is a very clever idea.

The fact that you can buy your music from anywhere on iTunes via the iPad, have it all auto backed up into iCloud via iTunes Match, work on your set on the bus or wherever, and then plug the same unit into your DJ gear for your actual performances, brings an undeniable cool factor to the modern digital DJ’s workflow, and surely we’re going to see a lot more of this kind of thing in the future.

For now though, if you are interested in iPad DJing, and you like Algoriddim’s djay software, you should seriously consider this as your next DJ controller.
