So that means: if I only have an mp3 song on a USB stick with the mcx8000 built in engine, I cannot analyze a song by itself
loops cannot be used (read from metadata stored on a USB stick)
Unable to loop on beatgrid (because there is no beatgrrid analysis) Am I right?
If you analyzed it before in engine with a pc and then exported it to a usb then yes
All these features can only be used if a laptop is connected with the engine software or the serator software.
The mcx8000 is a controller that can be used autonomously unlike the prime 4, for example, it is an autonomous equipment that can be used as a controller, it is an important clarification that denon does not do, that said
If you analyze your tracks with engine and then export it to a USB you can use the cue, the roll and the slicer in autonomous mode and you can create loops, the loops saved from serato are not imported
