I could always use more storage. I only have a 16 gb ipad mini with retina display. Current, I only have 2.3 gb left. Maybe that might be. The problem. This problem only happens on newer projects. The old ones are fine.
I don't do anything different from old projects to new ones. I use the iRig adapter to plug my bass guitar into the iPad when I'm laying down bass tracks. I use the drums and other instruments from the garage band and use the iPad mic to record my guitar parts (I only have an classical guitar without pickups).
I don't use 3rd party apps or loops. Nothing is really looped. I recorded everything straight through. From drums, I don't loop. I change the beat every so often and do different fills. So if I make a mistake somewhere I would re-record everything from scratch. Same goes for the other instruments.
I appreciate your time and support with my problem. :).
