I made some mash ups on my Prime 4 + how do i send those tracks to my phone or a thumb frive i use for my numark?
Your first port of call should be the user guide/instruction manual.
What @PKtheDJ was trying to say is we don’t understand the question, because you are probably mixed up some terminology…
Did you really create and save a mashup on the Prime 4+ (because that isn’t on its list of features as far as I know), or did you add a track to Engine DJ, which you now want to play on your Numark? In the latter case, look for Sync Manager, and use a USB stick (no phone)… Or, if I couldn’t guess what you meant, rephrase the question
I’m assuming Arkim recorded mashups onto storage media of some kind on/in the Prime 4+ but what? Flash drive? SD card? Internal drive?
What is “my phone”? Could be an old Motorola or Nokia from the 80s.
What is “my numark”? A turntable? CD player? Mixer? They also make speakers, mics, headphones and cartridges.
Actually it looks like they were asking the same basic questions over a year ago.
To answer your question, and assuming you recorded on to the drive you have in your P4+
Connect the drive to your computer and simply move the file to your computer, and from there to anywhere else you want it.
If you have recorded to the internal HD on your P4+, the connect the unit to the computer.
Its that easy.
But as PK said, there is good help in reading the manual.
