as I needed a backup controller, I bought two Kontrol One's, which are sold for only €39 in Germany, a great deal in my opinion.
I created a custom mapping for 2 controllers (Player 1&2, MIDI channel 1&2) for my own needs. No effect section, but Filter, Fine-Pitch, Browse and Beatjump on the Knobs. LEDs with Track-End-Warning, song position and some other things.
Maybe anyone find this useful
