Interesting topic.
I can say that i am an active user of iPad mini 2+djay 2 app+Pioneer Wego3. i am using this setup since Wego3 was released, before that I was using iPad mini 2+djay 2 app or Traktor DJ app+Traktor kontrol Z1. But! I must mention that the music and the events where i was using this setup, not always required active mixing or remixing. Sometimes there were an events where the mixing was required and I must say that using iPad+djay 2 app+Wego3 for basic mixing (or even with some effects) is very comfy. I am still using this setup (with Wego3) and I think its great option if: 1) you dont have to play all night long; 2) you do not do remixes on the fly; 3) event is a one-or-two-genre-event.
The disadvantages (IMHO):
1) The costs. iPad cost some money, djay app cost some money, controller will cost some money.
2) Storage is limited. I have a 32gb device, its quite enough for me. But i`m thinking about 128gb option.
3) If youre not using itunes, you will have to start. MediaMonkey Gold is another option, but sometimes djay app cant read the track, uploaded by MediaMonkey. Thats because the file name. Need to keep that in mind using MediaMonkey.
I cannot tell anything about using Android tablets or Windows tablets.
And interesting thoughts about Traktor DJ and variable beat tracks…i am using Traktor Dj with a laptop and i thought that if you using a dj software, you will have to deal with live drums by your ears =) Dj Vintage, is there any examples (video tutorials or maybe articles) that Cross DJ from Mixvibes is doing better with live drums that Traktor?
