Crash and sound distort a lot on my iPad mini

This app was super before it updated. Thankfully, I have own the older version on my iPod 4 and I fell this tiny device can make super tracks than on my giant home PC.
Now, I own iPad mini and download it. It provides the latest version. The UI is great. Friendly to use. However, I noticed that the sound quality distorted a lot. I did modify the sitting and now it reduced the sound distortion. And the app crashed a lot. I dont know if developers didnt test it on iPad mini. I feel my improved device with this app is like running its PC version on Intel pentium 2
