Damir Yes, I use iCloud and know its features well. I use iCloud to share data across 4 computers an iphone and ipad so I have to manage my shared data. I DO use it to share data between my performance apps (Gig Performer, L6 Helix, various controller backups, MIDI Pipe, Virtual Instrument patches, preferences, manuals...etc) all of which are small files.
In my experience, iCloud struggles syncing larger files like audio and video - which, I have read, is why Apple excludes those folders from iCloud sync. Moreover, I never want to be at a gig using some third party WiFi or trying to use my phone as a hotspot to download a file that failed to sync properly. Especially since iCloud does not provide tools to initiate or control syncing functions in any way. I see it's value if one's performance repertoire is relatively static, but I have a new set with new songs every single week. In the past I tried to use software that needed to access Wifi to authorize the app or plugin and found reliance on quality internet access at a gigs to be unreliable. Maybe if I could just download one or two missing audio files...but trying to download multiple audio files bundled in a single, large back up zip? No thanks. I carry my fail safe redundancies with me on flash media. It's a great idea, but it's just not for me at this time.
