Missing some essential features – Oval Synth Review

To claim this to be a new essential app for music creators tell me two things, either the developer doesn't really understand music production for iOS or hasn't done some basic homework. Any developer who doesn't add support for either Audiobus, inter app audio or audio unit, or all three, to an app for musicians doesn't get it. If it doesn't have at least one of those features it gets deleted.
