The ultimate Audio Unit hosting environment for macOS. Run your synths, route your hardware, and switch scenes instantly with zero latency.
A perfect balance between the immediacy of a stage keyboard and the depth of a workstation.
Easily access up to 8 instrument modules—each hosting up to 8 plugins—along with effects and macros on the surface, while deep routing and configurations run seamlessly behind the scenes.
Configure your workspace exactly how you need it. Color-code modules, assign custom icons, and drag to reorder strips to create a highly readable, distraction-free interface built specifically for dark stages.
Keep it incredibly simple or dive as deep as you need. Easily show or hide different UI sections—like Stage FX, Master Chords, Virtual Keyboards, Zone Splits, and Scenes. Switch between different View Presets instantly.
Build colossal sonic layers with deep sub-mixing capabilities.
The engine supports 8 independent modules, holding up to 8 voices each. Seamlessly switch between voices or modules while holding notes from the previous one without cutting off your sound. You can even load new plugins while holding notes without any audio drops.
In addition to 2 Insert effects per voice, every module features a native 3-band EQ. Plus, utilize 5 Stage FX slots, 3 Global Sends, and 2 Master FX slots. Load any 3rd-party plugin into these slots, give them custom names, and dial in separate effect levels per module.
Keep the sound engineer happy while hearing exactly what you need. Route a balanced master mix to the Front of House, and even assign a physical knob to control your independent stage wedge or in-ear monitor level.
Your physical gear and software instruments, working as one.
Take absolute control with massive mapping capabilities. Modulix features 475 assignable live targets, a 2,000+ trigger mapping capacity, and 1,280 dedicated voice macros that can directly learn and control parameters inside your favorite plugins.
Every voice gets its own macro assignments with visual styles: Knobs, Buttons, Drawbars, XY Pads, or Big Knobs. Save them per plugin, and next time you load your favorite organ, it loads with its drawbars ready to move.
Map complex jazz voicings and massive layered chords to single keys. Play a chord on your MIDI controller, and the built-in theory engine will analyze, name, and map it instantly to specific keyboard zones.
Advance through your show with zero latency and absolute confidence.
Organize your gig effortlessly. A 'Scene' captures your exact mix—active layers, splits, macro levels, and FX routing. A 'Song' groups those Scenes together, creating a perfectly structured setlist for your performance.
Advance through your setlist instantly. Modulix pre-loads your entire project into memory, allowing you to seamlessly transition between complex synth layers and routing changes without a single audio hiccup.
Never get caught off guard on stage. The built-in Differences Matrix visually highlights exactly which volumes, macros, and plugin states change between scenes, allowing for easy bulk-editing across your setlist.
Designed from the metal up to never drop a sample or freeze mid-song.
Built from the ground up to be exceptionally user-friendly while remaining incredibly powerful. Modulix’s efficient engine consumes significantly less CPU than leading alternatives, guaranteeing the lowest possible latency.
Turn it on for the voices you want. When an auto-sleeping voice is not actively selected, Modulix automatically bypasses it to save CPU. When you switch back, it wakes up so fast you won't even feel it.
If a buggy third-party synth crashes, your gig doesn't end. Modulix hosts plugins in completely isolated background environments. The core audio engine stays alive—simply reload the crashed plugin and keep playing.
Leave the mouse behind. Control your entire performance directly from your fingertips with the custom plug-in.
Unlike standard MIDI controllers with basic lights, the official Modulix plugin turns your Stream Deck into a deep, bi-directional smart surface. Keys instantly update to show exact module colors, custom voice names, and even dynamic icons indicating if a plugin is bypassed or sleeping.
Because you can see exactly what's loaded right on the keys, you can control almost everything without looking at your Mac. Step through setlists, toggle Stage FX, or page through 64 individual voices with absolute confidence. It provides the visual context of a high-end hardware workstation at a fraction of the cost.
Buttons actively adapt to your workflow. You can easily adjust zone layers, shift octaves, create and navigate through scenes, or trigger the Quick Split wizard where the button dynamically cycles steps as you play. It brings complex software editing right to your fingertips.
Modulix, MainStage, and Gig Performer are all capable live hosting platforms, but they are built with entirely different core philosophies.
MainStage is a powerful legacy tool deeply integrated with Logic Pro, and Gig Performer utilizes a highly customizable, visual node-based routing system. However, both often require significant time spent building UI layouts or drawing virtual cables before you can actually play.
Modulix is designed to feel like a hardware workstation. There is no "layout mode." The UI is pre-structured with color-coded modules, drawbars, and macros that are instantly ready for the stage. It hides the immense complexity of MIDI routing under the hood, allowing you to focus purely on performing.
Furthermore, because Modulix uses a strictly optimized, lock-free modern audio engine, it offers incredible CPU efficiency. In standard benchmarks running identical plugin setups, Modulix utilizes less than half the idle CPU of MainStage, giving you massive headroom for your heaviest synth layers without risking audio dropouts.
Modulix was created by Umut Erhan, a composer, multidisciplinary artist, and indie developer originally from Turkey and now based in France. Umut spent years serving as Musical Director and Keyboardist for some of Turkey's most prominent artists, performing thousands of high-stakes concerts.
Internationally recognized for his innovative live programming—including custom Korg Kronos soundpacks used by keyboardists globally—Umut noticed a fundamental disconnect with existing software rigs. While laptops offered limitless sonic depth, they often sacrificed the tactile immediacy and straightforward workflow of a dedicated hardware workstation.
Realizing that standard music software wasn't always built for the specific pressures of a live show, he leveraged his structural approach to design to build his own solution. Modulix bridges that gap: an environment that feels as immediate as a stage keyboard, yet seamlessly scales into a deep routing powerhouse exactly when the gig demands it.

Yes, as an advanced coding assistant. I completely understand the music community's skepticism toward "vibe-coded" apps built by people who have never written a line of code, but that isn't what Modulix is.
I’ve been developing my own software and custom MIDI hardware long before AI was publicly available. In fact, the core MIDI implementation and many underlying concepts in this app go back years. For the last year, I've worked on Modulix 10 hours a day to bring it to its current state.
I don't use any automated "vibe-coding" apps or tools. I built my own custom workflow where every single line of code goes through me. I use AI as a co-pilot to help scale the project, but I manually review, test, and write the critical components myself. This ensures I have absolute control over the architecture—if a bug happens, I know exactly where to look to fix it.
Ultimately, AI simply levels the playing field, allowing a solo indie developer to build something that used to require a massive corporate budget. (I also used AI to help generate the app icon and this website!)
