Sharing my GarageBand files with other iOS devices
So I am in a band with a few of my friends and we like to record our songs. Rather than paying for a cheap stuido we would perfer to make our own home recordings using GarageBand becuase the quality is not much lower. We would like to be able to record without having to always drive to each other's houses and crowd around one persons iPhone or iPad to record. What I want to know is: is there a way for me to share the tracks that I have in my GarageBand with my bandmates so that they can open the song in their copy of GarageBand and continue editing and recording tracks? It would be great if our drummer could record the drum track then send it to our guitarist who would do his track then to me for bass and our singer for vocals. So far I have heard of no way to do this. I know that iCloud can be used to share GarageBand songs, but this does not help since we all have different iCloud accounts. Also the export option in the app seems to be of no use. If I export by email then the recipent can move the song to his iTunes music library but not his app so that he can finish the song. It would seem like it would make sense to allow people to share their files so that they can be edited by others, but I could be wrong. Please, for the love of all things good in the world, help me.
