music files deleted form iPad after synchronization in iTunes on MacBook Pro
Hi,
Every time I sync my iPad in iTunes on my MacBook, about a 1000 tunes of my 7000 (all private, non iTunes/Apple bought mp3's and aiff, wav files) library is deleted and then re-copied to an iPad (what takes hours).
I have multiple library backups on external devices. I use my library to dj. Lately with an iPad controller (iDJPro). This auto-deleting and recopying is very frustrating as it takes hours. Especially happening before a gig.
I would appreciate any advice or solution <3
Macbook Pro 13" 2011 10.13.6 High Sierra with iTunes 12.8.2.3, iPad Air 2 14.3 (all - last updated)
All the best and happy new year!
Piotr
