Mad_Cyril I don’t now. I totally would, I mean I really loved it, but I had rekordbox/laptop failures during performances on some streams where the music would stop because of a bug or cable problem, or moisture / hot air being too much for the macbook.. whatever it was I never regained confidence in this method again so reverted to buying tunes.
You can record the sets by plugging a recorder into the back of your mixer/controller’s Booth Out and route it to field recording devices such as a Tascam DR05, Tascam DR-40 like mine (records crowd noise with inbuilt microphones during club events).
I’d just buy a used one.
Alternatively, if you have another laptop or computer (not the one you DJ from) you can get one of these and route the audio into it, and plug this into that laptop - it will convert the RCA signal to digital audio via USB to the computer for you and you can record via free software such as Audacity.
