QMix™-UC allows up to 16 musicians to simultaneously control their StudioLive™ Series III and AI-series mixer monitor mix, using an iPhone® or iPod touch®. Adjust each channel’s send level in just one aux mix or in every aux mix. QMix-UC’s unique Wheel of Me feature allows you to group multiple “Me” channels and to control all your critical channels with one easy-to-use control. For more advanced users, QMix-UC provides four customizable groups to simplify managing large mixes.

QMix-UC can connect to any StudioLive Series III and AI-series mixer on the same wireless network. Conversely, multiple devices running QMix-UC can connect to the same StudioLive mixer.

QMix requires an iPhone or iPod touch and a StudioLive Series III mixer (StudioLive 32 or StudioLive 16) or StudioLive AI-series mixer (16.4.2AI, 24.4.2AI, 32.4.2AI, RM/RML32AI, RM/RML16AI) connected to the same wireless router-based network.

Worked great for awhile, now un-useable in Landscape Mode, very fragile app

New SL32III owner

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.

Please add listen feature


Please add the feature so your headphones can play your mix via phone. This would change the game for everyone. You’re a step from it! Please give us this feature.

Broken After Update | Update: Working!

New Review:
For those of you who are having issues with the app crashing upon connecting to the board, I talk to Presonus support.

The issue is with incompatibility with certain saved Scenes. It appears they don't have it pinpointed yet but I was told they are 'working on a fix ASAP'.

To test this you can recall the "zero out scene" (after backing up your current settings). The app should work.

Now, recall your saved scene, but deselect "EQ and Dyn". The app should still work.

Now recall your "EQ and Dyn". The app breaks.

Hopefully this issue can be resolved by an app update, and not require another firmware update.

For me, due to issues with the firmware update to our RM32 AI, I lost a years worth of scenes. I had to setup our system from scratch last weekend. We re-EQed everything and wiped out all the old scenes. This also fixed the app/scene compatibility problems.

So I guess those of you that have problems have two options. Wait for an update, or wipe out all your EQ data and start over.

In the end.. the app is working again. But sometimes I feel like this all a Beta trial I didn't sign up for.


Old Review:
The app will launch but immediately crashes once I select the mixer.
