*Updating: I´ve tried a lot of solutions and only when remove Rekordbox, all drivers, re-install everything and when applying "default" again on MIDI panel then I´ve managed to get mostly of the functions back to normal state.
Still can´t get my sampler 2 (right side) to function properly. If I hit the buttons on 2, it plays the samples on 1 (left side), whatever bank of samples I try to use (1,2,3, or 4).
Hope someone get this message and give me some light on this issue. Otherwise, I will start to assume that "customer care" and "support" are not exactly important around here.
Thanks.
