do i need an audio interface software to export my 404 beats on to my computer?

You'll definitely need a Digital Audio Workstation of some sort. I think you can record directly into your computer Microphone jack.

Plug the out into your mic jack or the blue audio in jack, if you have it. Only drawback with plugging into the mic port is that it will be mono

imo its alot easier to just export beats to the card
if u have a OG 404 u have to buy a flashcard reader for 3$ online

the only advantage i see in recording out to the computer is if u r doing a long live session or something like that

for me i would record beats out of my 404 to computer but sometimes the levels would be all fucked up and ect..
then i bought a card and export beats it actually sped up my process
