I'm looking for some testers to find out if there are any issues with my app. It is already live in the app store but want to make sure all is working well.

The app is a colour noise app that can generate white, brown, pink and also black noise. It's unique in that it features a 10 band parametric equaliser and high and low pass filters to further manipulate the sound to get exactly what you want.

Any feedback about actual bugs or incompatibilities would be particularly useful. Any general feedback would certainly be welcome too. Thanks in advance for your help.
