I would really like to be able to have my playlist mix/segue together in the main output. It would also be nice to be able to select what type of mix as well. Mix types could be…
Beat Mix (Match BPM & Select length when to start mix before track ends) Radio Mix (Begin next track when previous track begins to fade out) Continuous Mix (No spaces in between tracks)
Mix length should be adjustable (customizable to fit user’s needs)
This needs to be available in the next update.
I mean, at that point you might as well just be using a computer with traktor and an audio interface, if you’re gonna let the computer dj for you. :-p
There are multiple request for this feature for the Prime GO, Prime 2 and Prime 4… Here is a link to one i started… You can add your support to the list… Just click on this link and request it for Prime 4… Your requesting Continuous mode have Automix capabilities. A valid request.
