I have a 30-pin iPhone/iPad. Can I connect it to DDJ-WeGO3? [djay for iOS]

If you use a separately-sold DJC-WeCAi30, you can connect to DDJ-WeGO3 to use it.

The compatible models with this cable are iPad (3rd generation), iPad2 and iPhone 4s.

For details of the compatible models, please see the Pioneer Support page.
