Top 4 pad modes are Hot Cue (8 hot cues, press the square record button in the middle of beat pad acts as shift and this delete hot cues), 

Press Hot Cue again for second layer - top pads are to alter grid position and load a marker and bottom left 3 are kill switches - 

Auto Loop (1 beat to 128 beats - top 4 pads light up but bottom 4 don't) 

second layer is top pads in and out manuel, exit and right pad are loop length up and down

TouchFX top pads FX on and bottom momentary almost like midi fight style and if you use gain knob its alter the wet/dry perimeter - very cool. 

Slicer acts as STEMS now with top 4 pads acting as mute and if you press shift on the beat pad (bottom right or left) and hold it, it acts a second layer of control and this controls the volume of the individual stem. 

other functions are hold shift will sync (set grid), set (slip mode ala flux), Jump (back to zero and play (turntable brake)

Hold shift and press - key is key lock on or off, hold shift plus 1 or 2 load button is turn effect pad on screen, hold shift plus gain is gain. (i don't use gain that much so i thought just gain on his own is better towards effects wet/dry)

shit plus cue = jog scratch on/off

shift plus jog wheel = scroll quickly through track

shift plus record = record

Enjoy :)
