Hi, we've read your concerns and are aware of them. As I stated previously, the app was not designed for chromatic play and adding these features now is something that would break session compatibility for our users, which is a non-starter. I'm sorry that the app does not do exactly what you want, but incorporating the features you request would require rewriting most of the shift / delay grouping / panning UI/UX. This is something more likely to make it into a different app than as an update for QVox. The preset overwriting issue is logged in our system and will be addressed in a future update.
By the way, we do read App Store reviews and care greatly about user feedback – we monitor the reviews and respond as appropriate.
