I've always wished that when I discover two tracks that mix well together that I could simply push a button that remembers that particular mix. Then the next time I select that track a pop-up window would appear and show me a list of all the tracks that mix well out of that track (based on the mixes I've indicated work well in the past). Then as time goes on and you discover multiple tracks that mix well out of a particular track it would remember all of those potential mixes and suggest them to you. Rekordbox is the only other DJ software I'm aware of that offers this exact feature. It's called "Match". They beat NI to it, but I'm sure NI could one-up Rekordbox by offering a more advanced version of this very feature. Perhaps provide a way to quickly preview the suggested mixes without actually having to load the suggested track? Hmm...Rekordbox may actually already do that as well. Ooh!!! Here's how you could one-up Rekordbox... Provide a feature within the "suggested mixes for this track" window that would also suggest exactly at what time you should mix each of the suggested tracks into the current track. For example, I always make a note in the comments section of each track which denotes exactly where in the track I should drop the next track in (I.E. drop next track in when 1:30 seconds remain in this track). Perhaps just create an automatic marker on the current track which shows where you want to drop the next track. The marker position could change as you scroll through the list of potential tracks to mix into the current track. This could be done in several different ways to make it a little more elegant than how I explain. You get the idea... Either way about it, this would be of MONUMENTAL help for all Traktor DJs. I'm tired of having to create playlists to remember tracks that mix well together. This wouldn't be too hard would it? Thanks for keeping an open ear to us DJs' suggestions!
