I actually try to use all 8 in traktor mainly because recently I have been doing alot more cue point juggling. Every song has interesting/recognizable parts that can be used
#1 Load marker where I want the song to start
#2 An alternative start to a song. Say its liek a trance track that has a long into. I may want to start it further into the track
#3 Breakdown/Vocals/Build-up (pending on the track)
#4 The Drop /Mixout Point
#5-6 Mixout Point
#7-8 Snare Drum, Vocal or anything interesting really towards the end of the track that can be used
I also tend to write comments in traktor for some cue points. Mostly for vocals . Like if in the song theres a part that says “Drop the bass” I will write that down. It heps me to find more commonalities between music. I like to mix alot of gneres so so mixing with words is another way for me to bridge the gap between genres.
