I do live DJ work. I play music for parties and the like. My old Numark CD mixer is bighting the dust and I need to go in a different direction. I am trying to get away from playing CDs live from a CD mixer and putting my stuff on either a pc or a smart phone. Some new numark mixers seem to offer some help in that direction. I can get a mixdeck express which has duel CD drives and USB ports for hard drives, thumb drives etc.. You can all so plug this mixer in to a computer and use it as a DJ controller. The other way is a CD mixer with Bluetooth capability that will play audio from your smart phone. They say that the transport controls will work with the phone or laptop but they mention no DJ software to control your music with. I think just the audio and some limited key mapping is all you get with that mixer. I need to find a direction. Which deck would you recommend and what DJ software would you use to drive the mixer. I know that the mixdeck express will use something called surado dj and virtual dJ. And something called tractor. I don't know if you can use replay products or Sam DJ or zello, station play list any thing that I have had some success with when I have experimented with software in the past. I needd lots of help I have an android phone but have know idea how to connect a Hard drive to it. I could upload music to the cloud I suppose. I could use an Ipad or some sort of I device but I don't necessarily want to use I-tunes software. Lots of questions I know but there are some powerful brains on this list that can help me think on what to do.
