How to calibrate DVS with DJM-A9 and CDJ-3000?

[Akifumi_Konishi]

I want to connect my iPad to DJM-A9 via USB cable and play rekordbox or serato DVS signal on CDJ-3000 via USB memory and enable DVS with iPad.
DJM-A9 is class compliant, so it is recognized as Audio Interface on iPad, but DVS signal did not display and could not be calibrated.
Incidentally, DJM-A9 and CDJ-3000 had connected by line or digital cable.
Please tell me how to do calibration.

iPad mini 6
iPadOS 17.6.1
djay pro 5.2.5

If you want to use Rekordbox or Serato, why are you asking on the Djay forum?

Hi @Akifumi_Konishi,

1. You will be using the A9 in External Mixer Mode in djay so all of the mixing will be done on the hardware instead of using djay’s internal mixer.
2. Note that djay only supports 1kHz time code signals, so make sure that’s what your CDs are using.
3. When you want to use cues on the player you should consider using ABS mode, otherwise it can become confusing.
4. For more about DVS setup please refer to the links below:

How do I calibrate turntables for DVS in djay for iOS?

I’m using djay Pro.
DVS signals are files released by Rekordbox or Serato.

I have it connected like that, but I couldn’t calibrate it.
I was able to calibrate using Denon DS1 as audio interface.

This post states that DVS could be used with turntables, but not with CDJs.

The post also states that you can use DVS with CDJs by connecting PHONO through a converter equipped with a reverse RIAA filter.

Does djay Pro for iOS only accept PHONO input when using A9?

Hi @Akifumi_Konishi, DVS should work with CDJs as well. The calibration settings are found in the djay Settings>DVS.

I believe both users in the linked topic below were able to get this type of setup working. Although with different mixers than yours.

1. Perhaps there’s an issue with how you are connecting to your iPad. Are you using a genuine Apple Camera Connection kit and is it connected to power using your original iPad charger and cable?
2. Are you running the latest firmwares on your mixer and CDJs?

Pioneer v10, dvs and cdjs

Hi there, I’m looking to use djay pro on my MacBook Pro, connected to a pioneer v10 with two turntables using dvs and two cdjs 3000. I may potentially expand out into a djs1000 into the future. Just wondering whether this kind of setup is possible with djay pro? Also could someone explain the limitations of the v10 not being supported by djay pro. Does it mean I have to do the mappings myself or is there more to it than that? Thanks

CDJ as DVS on mobile Devices

Hi everyone, one question: Has anyone tried to use Pioneer CDJ as DVS device via ios? In terms of the idea, this should work in exactly the same way as when turntables are used, right? So a timecode signal via USB stick into the player, activate DVS on the iPad and then get started with e.g. a Pioneer DJM S11. Many thanks in advance

Settings>DVS selects the A9 channel.
But djay can’t receive DVS signal.

The iPad mini6 and A9 are connected via a USB-C cable only.
Of course, there is no problem if you just use the A9 as an audio interface without using DVS with this connection method.

Mixer and CDJ firmware are latest version.

Could you also verify it on the Algoriddim side?
