So for the most part the app is decent, however I'm creating R&B vocals & as soon as you get up to 6 tracks the app starts glitching. The app is advertised to be able to lay 12 tracks & I can only lay 5 at a time because the 6th one makes the app glitch, deletes my progress & just shuts off. So I constantly have to be saving & downloading the same project in order to get it done, so not only is my storage space getting full but 1 project that would usually take me 2-3 hours took me 8 hours.
