    I enjoyed this app. I am not sure how good it is at making audio that you can use in DAWs but the app felt very easy to understand and get results making simple melodic phrases with.

    My status bar drops down and covers the controls and colors and I have to wait for it to pull itself back up before I can choose another color plus it needs portrait mode.
