Sync,rev,cue and treble/bass/volume knobs have been switched for effects on both channels. fader is now a filter. pitch bends have been replaced with transpose effect,turtable FX, Echo out, and deck focus. Browse knob is not loop set/selector. Jogwheels and scratch button are unmapped. Good replacement for a midifighter if you dont have one. Works well with an additional mixer as the mixer on here is just FX.
