MixtetXR18 monitor mix app · for bands without a sound engineer
Every musician mixes their own in‑ears on their own phone.
Mixtet is a Mac app that turns your XR18 into a band system. Each member scans a QR code and mixes their own in‑ear monitor in the phone's browser – nothing to install, and no way to touch someone else's mix or the house. The band leader runs the house, scenes and a MIDI controller from one place.
- Members install nothing
- Each phone controls only its own mix
- The mix keeps playing if Wi-Fi drops
Built and tested on a Behringer XR18 · runs on a Mac · free beta
Sound familiar?
“More me!”
One person ends up mixing for everyone, and the gaps between songs go to fixing monitors.
“Who touched the master?”
The phone app can do everything, so someone moves the house or another person's mix by accident.
“The app dropped again – enter the IP…”
The phone goes to sleep, the app loses the mixer and rehearsal stops to look for an IP address.
How it works for band members
Three steps, no app to install.
- 1
Scan the QR code
The band leader shows you a QR code – on the Mac or printed on a card on the rehearsal-room wall. Your phone camera opens your monitor mix in the browser. No IP address.
- 2
Mix yourself
Big ME and BAND sliders, volume and Mute my mix. Want more? Open individual channels and star your own.
- 3
Locked to you
Your phone controls only your monitor mix. You can't change the house or anyone else's mix – the Mac enforces it, not an app setting someone can switch off.
For the band leader – the whole mixer on a Mac
The Mac shows the whole band's mix. Everyday controls are big and close at hand; the sound-engineer stuff stays out of the way until you need it.
A mixer that looks like a mixer
Faders, meters, MUTE and mute groups. Channel colour = who owns it, so you see whose guitar it is at a glance.
Everyone's monitor mixes
See what each member hears. If someone can't hear a channel, the app tells you why and offers a one-click fix.
Concert mode
Big type, NOW PLAYING / NEXT song, big MUTE buttons. The space bar toggles a mute group – say, silencing the instruments between songs.
Channel, made simple
“Does the kick sound right?” Level, Clarity and Evenness. The full EQ and compressor only when you want them.
Quick edits next to the mix
Pick a channel and adjust EQ, dynamics and monitor sends on the right without leaving the mixer.
Songs and scenes
Every song has its own mix. Scenes change the house, never the monitors – and you see what will change before you load.
Screenshots show the app with a demo band. The Mac app is in Czech for now (English is coming before the international beta); the members' phone page is already in English.
Built for musicians, not sound engineers
Set it up yourself in one evening. The app speaks band, not engineer, and never does anything behind your back.
10-minute setup guide
Connect to the mixer, choose who listens to which mix, check every channel and hand out QR codes – one thing per screen.
Try it without a mixer
A demo mixer runs on your Mac only. Learn everything at home before rehearsal.
Band words
“Tom's monitor mix”, “house”, “mute group Instruments”. No Bus 3 or LR in the main labels.
Ear safety limiter
A limiter on every monitor mix – a bang or feedback can't blow past the ceiling.
Pre-show check
Mixer, backup, limiters, phones, controller. Anything off is flagged yellow with a fix button next to it.
A controller in your hands
Korg nanoKONTROL Studio is pre-mapped: faders, MUTE, Play = mute group. Teach it other controllers with one move.
Never pretends
A value only counts once the mixer confirms it. If Wi-Fi drops, the mix keeps playing as it was and the app tells you.
Every step can be undone
⌘Z even undoes a loaded scene. A log shows who changed what – the Mac, the controller or a member's phone.
We're looking for 50 founding bands
The beta is free, no card, no commitment.

What you need
A Behringer XR18 mixer
We build and test on it. XR12, XR16 and Midas MR18 speak the same protocol – we're looking for testers with them.
A Mac with macOS 14 or later
Mixtet runs on the Mac. iPad is on the way.
A Wi-Fi router
Recommended. For rehearsals the mixer's own Wi-Fi is enough.
Members' phones
iPhone or Android, just the browser.
In‑ears or headphones
From the mixer's monitor outputs – wireless or wired.
MIDI controller – optional
Korg nanoKONTROL Studio and others.

FAQ
Is this a Behringer app?
No. Mixtet is an independent app, not affiliated with Behringer or Music Tribe.
Do band members need to install anything?
No. They scan a QR code and their monitor mix opens in the phone's browser. They can add it to the home screen as an icon.
Does it work with XR12, XR16 or MR18?
They use the same protocol as the XR18, so they should. We haven't verified them on real hardware yet – we're looking for testers who have them.
Is the app in English?
The members' phone page is. The Mac app is in Czech for now; an English version is coming before the international beta wave.
What if Wi-Fi or the Mac drops out?
The mixer keeps playing as it was. Mixtet never sends blind, and both the app and the phones reconnect on their own.
Does it work on iPad or Windows?
The members' page works everywhere. The band leader's app is Mac-only for now; iPad is on the way. Tell us in the sign-up what you'd use.
What will it cost?
Nothing during the beta. We'll set a price based on what testers tell us, and founding bands hear it first.
What happens to my data?
We use it for the beta only and delete it within 2 years at the latest. Email us any time and we'll delete it right away.
Who's behind it
Mixtet is built by KRAI, a band from Litoměřice, Czech Republic. We play an XR18 without a sound engineer and test the app at our own rehearsals and gigs. Questions? Email [email protected].
