Pioneer DDJ-SX2 - When decks 3 and 4 are chosen the effects section on the controller only applies to decks 1 and 2.

It looks like the MIDI input for FX on decks 3 and 4 are the same as decks 1 and 2.

So when trying to apply an effect using the controller on deck 3 it actually applies to deck 1 instead. I took a look at the default MIDI mapping and it appears that decks 1 and 3 have the same MIDI inputs from the controller. Any ideas?

I can post more info if necessary.

same here - no fx possible for deck 3 and 4… solution?
Just bought the SX2 2days ago, especially for 4decks… bit of a shame not being able to use the fx for these decks…
Tried the same in Serato - there it works… but prefer DJay…

Has anyone figured out a midi map work around so that we can get the effects working on Decks 3 & 4?

Has Algoriddim staff responded to you?
