dj tech dif-1S V2 ?

Anyone know the difference between the dj tech dif-1s and the dif-1s v2 ?

Thanks

Addition of midi controls and master cue

I have the DIF 1S and the lack of midi controls doesn't bother me but the having to hack a cue is a bit of a pain. I think the DIS 1S is at a bit of a discount ~$50 compared to the DIF 1M so that might be a bit of a factor for some.
