MXBus is a monitor mixing app for all Behringer X32 and X-Air mixing consoles that allows musicians on stage to control their own monitor mix with their iOS device. It also supports the Midas versions of these mixers (M32* and M-Air) It features stereo channels to save screen real-estate, namable groups and automatic console discovery. Musicians can control the send levels into their monitoring mix bus for all channels aux tracks and effects returns. You can even reorder the channels within your groups to your liking. It makes the sound check painless and allows you to adjust the mix during the gig. Some key differentiating Features: • Linked channels are treated as a stereo channel to save screen space. • Double tapping a fader knob sets it 0. • Double tapping the panning control on a stereo channel pans the signal hard L/R. Another double tap reverses the panning. • NEW: Springboard and Lock Screen widgets for quicker access. And as always: The app is built with data privacy in mind - no adds, no tracking! The PRO pack unlocks even more features like: • Decayed meters with peak memory • Compression meters • Gate LEDs • Channel mute buttons (X32) • Group mute buttons (X32) • Unlimited groups • Scenes • Bus EQ • Bus Compressor

Verdict
The clearest difference is rating: MultiTracks.com ChartBuilder at 4.8 against MXBus's 4.2. MultiTracks.com ChartBuilder also leads on ratings volume (6K vs 120) and chart position (#121 vs unranked). MXBus's advantage is monetization model (free with in-app purchases vs subscription). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. MultiTracks.com ChartBuilder sells 4 in-app purchases, starting at $2.99 per month and MXBus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
MultiTracks.com ChartBuilder holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: MultiTracks.com ChartBuilder has 6K ratings behind it against 120, so its average is the more settled of the two. Written reviews complicate that: 63% of MultiTracks.com ChartBuilder's written reviews are positive against 70% of MXBus's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 9, 2026 and October 10, 2026 respectively.
