hey cellomusicnow,and everyone who encountered the same problem,

I am not a Xkey user but I use a similar bluetooth midi keyboard device of KORG.Same thing happened to me. Everything eles is fine, but when running Logic, Bang, disconnected.

I just deleted all the caches of Logic in the Library. I’m not sure which one(s) is the one I really need to deal with ,so I deleted all of them (didn’t delete the downloaded sound resources).

I use this application called App uninstaller to delete these caches, it’s more convenient than do it by myself. After deletions my keys runs normally in Logic again!

It’s not an ad for Korg or this app, I just know how frustraed it feels that this thing you bought for convenience now becomes the most inconvenient sh– lol.

Hope it helps man!
