I'm just going to add to this topic. I'm now using the Rane MP26 19" Club mixer with mix emergency. The mixer connects straight to computer via USB. I've currently got the up faders mapped to channel one for the left deck, and channel 2 for the right deck of ME, i also have the crossfader mapped to the crossfader in ME. I don't use the crossfader as such, as i'm not a scratcher, and i have ME 'Link to Up faders' option in use, and this works fine for me. If i also want to record my video set, the audio can be routed from the mixer straight into ME, after configuring the output in Rane's MP26 config software, and then in ME software. The MP26 is not a scratch live or itch mixer, so the use of an SL box (SL3 in my case) has to be used. The MP26 has a 'matrix' style input so you can choose upto either Analogue, auxillary (phono if required - by setting the push switch on back of mixer) and each of the 4 channels has a 'Digital' input by the means of using the core audio or asio drivers as the mixer has an inbuilt sound card for both inputs and outputs. So if you wanted you can run scratch live and traktor at the same time if required on all 4 channels and have CDJ's and Decks connected if you wanted to go that far. http://www.rane.com/mp26.html
