And, of course, this is all great if you actually have a Mac to go and use some pro-level plug-ins - Logic Pro is only on Apple products. However, if you do not have the sounds downloaded on your Mac that you have downloaded in the iPad version, Logic Pro will automatically download those sounds for you when opening the project on the Mac, and vice versa. Apple says Logic Pro for Mac will have a compatibility update today to make it work with the iPad, including the ability to open tracks with non-editable versions of Beat Breaker or Sample Alchemy, but no word on when the full version of those plug-ins will come to the Mac version. So if you’re going back and forth between devices on one project, you’re going to have to think about what is compatible with what version. Another stumbling block is when I transferred an iPad project to the Mac, an audio sample from the library was not available on my desktop.
