Dj pro 2 app won't recognize my DDJ-SB3m pioneer controller, wondering if others are having the same problem?

maybe it only works with Serato

I’d phrase the answer as follows – Djay Pro 2 does not currently support the DDJ-SB3 at this time however they have indicated there will be support in the next update of djay pro 2. You can see the list of all supported MIDI controllers at the bottom of this webpage: https://www.algoriddim.com/hardware

It is NOT A PROBLEM because Djay Pro is not supposed to support it.

Hope this helps!

thank you!
