Reply to Pioneer DDJ-SX Traktor Mapping Help

Hey guys, ive been using the Pioneer DDJ-SX Viper mapping for a few weeks now. However, I i noticed early on the effects dont work as they should. I have the gater working and the beatmasher, but the delay (mapped to pad 1 ) doesnt work. It also seems some of the effects work and some dont. Does anyone have any idea why? Shift+Slicer opens a new bank of effects, flanger, lofi and zzzzrp works but delay and delay t3 dont. Does anyone have this mapping working correctly?

Also is there any documentation as to how Viper mapped each button so we can change it to suit ourselves?

Thank guys
