Man, that did take long for me……
i did not get, that every colored bar, stands for each track or better that i have to download em separately……

Dude that is so easy (when you know) and mindful……
Wow, now i have a real usefull App that brings me a Lightyear ahead, thanks a lot!!!
For others who read and need that, just download all the Tracks from the "Song" you created, (on a Mac) select them all together and drag them to an empty Garageband Project, it will make a Track for every File that you can Loop again forever and do Effects and whatever you´ll need on it. Just simple and Nice
