What i really miss when not using Serato is how the cue triggering works.
When playing with Prime and hit a cue point the song will play to the upbeat and then skip to cuepoint, or if you are a bit to late it will play to the next beat and jump. So if you set your quantize to 4 beat and you just miss and hit it a tad late, it will continue 4 beats before jumping to cuepoint.
When doing this with Serato it will jump immediately. If you hit slightly before the upbeat, it will jump slightly ahed the cuepoint. if you hit it slightly after…it will jump slightly after. One of the reasons i like this is because i always set my cuepoint on the beat, but at some songs the vocal or other sounds will start slightly ahead of the beat. So hitting the cuepoint slightly ahead will catch up this.
