PreSonus QMix®-UC 4+

My church has used this app for several weeks now with little issues. However, this past week, the levels for two separate mixes defaulted back to an unknown default setting and would not allow us to adjust levels until closing the app and reopening. This is a huge issue with live performances as several instruments in the mix suddenly change volume levels. In addition to this recent issue, several phones have not been able to use the landscape setting and therefore they cannot adjust levels at all. This is also a vital issue as the app is basically useless to those individuals. Please update this app and correct these bugs. I noticed it’s been 2 years since an update and reading through the reviews, these are common issues and my problem is by no means unique.

Our music group purchased a Studio Live 32 Series III mixer in Nov. 2017, we all installed QMix-UC on our iPhones (and on one iPad) and everything was working wonderfully! Using router specified by Presonus (TPLink unit). About a week ago (corresponding we think to the release of iOS 11.2.2 on January 8, 2018), this program no longer runs correctly. Cannot select an Aux mix even when given permission on mixer. Only remembers the last aux mix assigned prior to problems starting a week ago. Only the Wheel of me works, landscape mode is either grayed out or non-functional. Most devices will not go into landscape mode (where the individual faders of an assigned aux mix and groups can be accessed and controlled). We see over the history of this app that many problems are linked to releases of new iOS versions. We think this is probably the case here maybe. Having this program to run our individual aux mixes was a major selling point to us to purchase the new digital mixing console. We had to learn the hard way also to not let our devices go to sleep, else you have to start all over and reconnect to the mixer/go though permissions set up all over again (known problem reported by other users). Have tried to contact Presonus technical support to no avail, on hold for 1 hour and 40 minutes, no response, Finally gave up.

The app itself is fantastic. Our church has been using this app to control musician’s mixes wirelessly for years. However, it MURDERS every battery. We just compared battery stats, and they were unanimous. It doesn’t matter what software version you’re on or how new your phone is (brand new iphone here). Through leaving the app on and connected for 20 minutes, we usually lose 15-25%.

As I said, the app works great, and does exactly what we need. But if the battery issue could be fixed (or at least reduced), that’d be worth a 4-star review. (I don’t believe 1 or 5-star reviews should be taken seriously).
