I'm having an issue (Rane 62, MBP 2.4 Ghz i7 with 16GB Ram, Serato DJ MixEmergency), the crossfader stops in the center, and on occasion I have to bring the fader back to the center point to get it to complete the transition. It also seems to do it on the upfaders as well. Both faders are controlled (up & down) on PGM 2. However PGM 1 works independently. I'm not "super" midi savvy... so I didn't want to keep tampering with re-assigning or have it re-learning. I was able to map a MPD 24 to function with just Serato Video in the past and I never encountered any issues but I am clearly stomped here.... Thanks
