• Version of operating system (e.g. macOS 14.4.1):
• Version of djay (e.g. 5.1.2):
• Hardware/controllers used (e.g. Reloop Mixon 8 Pro):

Your question/suggestion/feedback:

After about two days of back & forth questions and answers with chatgpt, it suggests I will be able to output stereo to my amplifier whilst also having precue for the next track whilst using the on screen iPad software Djay Pro as controller (I don’t want a hardware controller) by using a Presonus Revelator I/O24.

Is this correct?

Hi @Andrew_Hart, there are 2 key requirements for an audio interface to work with iOS and provide stereo headphone cueing and stereo main audio.

1. You need 4 audio outputs: Left and Right for headphone cueing and Left and Right for main audio output.
   a. Looking at the back panel of this device is does have stereo main output and stereo headphone output.
   
   
2. The device needs to be USB Class Compliant. This means it needs to work without the need for specialized drivers since iOS does not support driver installation. According to the user manual, there are drivers to download and install which makes me think this is not suitable for iOS. It’s possible that the drivers are optional, but I recommend that you contact Presonus Support and confirm if this device is USB Class Compliant, will work with iOS devices and does not require driver installation.

iPad Pro + Reloop Flux

iOS 17.6.1 I just wanted to report the excellent integration when using the Reloop Flux with my iPad Pro. At the moment, I am using it with a Numark dj2go as the midi controller and streaming the djay visualizer. At first, I was having latency issues and audio drop outs. I was also having a quick static sound when cue’ing. It was usable, but not perfect. I did some research here in the community forums and found that turning Bluetooth off on my iPad might help, well, it sure did. I’m exper…

There’s also a good discussion here about audio interfaces for iOS:

Precueing using external USB sound cards

For headphone preview/pre-cue in iOS your audio interface needs 4-channels (4 out). This will show up in djay Pro as stereo channels (1-2) and (3-4). Examples of 4-channel (4 out) audio interfaces: MOTU M4, Audient ID14, SSL 2+ (Plus!), Presonus 26C and Scarlett 2i4. Tip: iOS uses the last audio interface that was plugged in. So plug in your DJ controller 1st and the audio interface 2nd. Your DJ controller won’t show up as an audio interface but you can still use it to control djay Pro. Notes…

Just wanted to add some input for anyone reading this thread - sadly the Presonus revelator io24 does NOT work with iPad. It is recognised but the audio comes out the main and headphones and no matter what combination of in/outputs I selected, I could not get it to work.
I have an M-Audio AIR 192/8 arriving today which I have seen working with DJAY Pro on youtube so fingers crossed it still does. It was more than I wanted to spend but should be a nice bit of kit.
Thanks for your replies Slak_Jaw.

You’re welcome @Andrew_Hart. Thanks for sharing your findings.

I received the M-Audio AIR 192/8 and can confirm it works. Bit pricey just to get stereo out vs the traktor splitter cable’s mono but it was the only interface solution I had confirmation of working and didn’t want to risk purchasing any more untested options (I spent £59 on the presonus revelator io24 second hand so now I have to sell that!).
