With PreSonus QMix™, up to ten musicians can simultaneously control their StudioLive™ monitor (aux) mixes using an iPhone® or iPod touch®. Adjust each channel’s send level individually or use QMix’s Wheel of Me to control the relative levels of multiple “Me” channels at once. QMix can connect to any StudioLive mixer over a wireless network. Conversely, multiple iPhones and iPod touches running QMix can simultaneously control the same StudioLive mixer and you still have Virtual StudioLive (VSL), SL Remote, and hardware control.

QMix requires a Mac® or Windows® PC running the latest version of Universal Control (which includes VSL) and a StudioLive-series mixer. The computer and mixer must be connected and synced via FireWire 400. VSL must be launched in order for QMix to detect a StudioLive mixer on the network.

Almost unusable on iPhone + models

1.4.5 update:
Screen layout and resolution is still terrible. Seriously, have you even opened this in a live environment??

1.4 update:
Well, it's usable now but it might use half the screen on a plus model phone, which makes it very difficult to use. Did you guys use a iPhone 3G to test this or something??? Your up to 2 stars

Appreciate the update to 64-bit. Unfortunately it constantly crashes now. I'm unable to even adjust the "me" volume.
The resolution is totally off for the display (6s+)
Parts of the display, especially after a screen rotate, are off screen. Gear icon to change setting and define "me" seems the be missing at time. When it is there it doesn't consistently work.
I'll try to continue to update as I find more

Update non-functional

Since updating my device does not show up on computer to be assigned and I can't adjust any mix even though it says it's connected. The display doesn't fill the entire screen either and seems slightly out of focus.

Presonus you guys are great and I know you're working on the issue. Thanks for supporting such an old product!

For years this has been stable system for our church. Using SL -remote and Q mix is essential as we often do not have a dedicated sound person. This update has ruined everything, I've gone through all the steps mentioned on the presonus site. Updated UC to completely removed all presonus software and re-installed. Reinstalled the apps...nothing works. I'm locked out of the SL-Remote and Q-mix even though the connection is there, no device is shown on the Remote Devices: in setup within Studiolive
