Traditional musical instruments are difficult to learn because notes are arranged based on physical constraints.  Musix Pro arranges notes based on their harmonic and musical relationships instead, allowing shapes and patterns to emerge that unlock the mathematical beauty of music. 

What is Musix Pro:

- A professional musical instrument and midi controller
- Learn one pattern and instantly play in any key
- Explore the harmonic relationships between notes
- Play music easily without sacrificing virtousity
- An isomorphic layout creator and experimentation app
- A melody exploration device

Features:

- Core / Virtual / Bluetooth Midi, OSC
- Supports all MIDI / Audiobus DAWs
- Touch Velocity Dynamics
- 8 Built-in instruments
- AudioBus Support (MIDI sender, Audio sender, State Saving)
- Hexagonal and Rectangular layouts
- Multiple built-in note arrangements
- Custom layout generation and saving
- Colourize different notes based on key, scale, and mode
- Label notes based on Solfege, or Note name 
- Multiple note sizes
- Multiple color patterns
- Note Overlap (play 3-note chords with one finger)
- Full iPhone Support

Unlike other music apps, Musix Pro provides a wide range of octaves, scales, keys, chords and modes, without limiting your creativity. With multiple built-in instruments and support for OSC and Core/Virtual Midi, most existing synthesizers work beautifully with Musix Pro as a controller.

ADDITIONAL INFORMATION:

Musix Pro is key agnostic, which means is that once you have learned a musical pattern (like a chord or a scale) that pattern is the same for all keys, even the dreaded A-Flat! Sharps and flats appear in the right place automatically, through the mathematical magic of isomorphism. You can learn to play melodies on a traditional keyboard by playing them on Musix Pro and watching where the sharps and flats go.

Songwriters benefit by discovering new melodies and musical relationships. Novices find it easy to learn to play. Experienced musicians are rewarded with an intuitive interface. Keys can be resized to fit your style - start with "epic"-sized keys, and as you get better you can shrink the keys fill the screen with notes.

Isomorphic keyboards are found on traditional and new instruments, from concertinas, accordions, and "jammers" to Janko keyboards, harmonic-table devices and more. Musix Pro is the only way to access all isomorphic note arrangements in one powerful customizable application. 

Musix Pro comes with a set of built-in layouts, each with its own pros and cons. The harmonic table layout allows you to play any major chord by touching three hexes with one finger. Wicki-Hayden makes modulating between pentatonic scales a breeze. Try them all and find one that works for you.

Musix Pro allows you to change the colour of the notes in your layout.  You can colour the notes white and black like a piano; you can colour the notes of any scale or mode (like D-flat mixolidian) and you can colour notes based on tone centre.

### 3/5 — the mpe seems not woking？

*2025-09-27*

I cant glide on Musix pro

### 5/5 — Musix Pro Opened My Mind to Music Theory! Love it!

*2025-07-11, version 2.5.6*

This app convinced me that I could learn music theory in my middle age. It’s fantastic at what it does and I hope it lives on forever. 

It’s nice to see a developer who sticks with their creation over a long timeline. In this age of disposable apps where devs try to hit the app jackpot and then a year later it’s abandonware, Musix Pro has been around forever.

Someday, when its dev decides to retire, hopefully they can pass the torch (source code) on to another dev or the open source community. This app is too cool to get lost to history.

### 5/5 — great app  , learn scales easily

*2025-04-04*

keep up the good work , you can make it even better by implementing a few changes : 1/ make it possible to rotate the grid by 45 degrés angles ( not just 90 degrés horizontally or vertically ) . 2/ make it possible to orient  the grid up or down , instead of having me locking the screen then rotating my ipad . 3/ make it possible to rotate the notes letters in the hexagons  by 45 degrés all the way round  , so to have them correctly oriented when you rotate the grid  , aka rotate the notes writing independent of the grid rotation . 4/ add a metronome .  5/ add a piano instrument .6/ give the choice to annotate notes  as sharp or flat , for example i prefer  to read C sharp , F sharp , but i prefer  , E flat  , A flat , B flat

### 2/5 — Needs XY expression

*2024-05-06*

I've had this app for years and while velocity and chords have been nice additions I don't understand how it still doesn't have basic features like pitch bend. 

EDIT: Now they've removed support for split screen which kills usability with other apps on the iPad.

**Developer response:** Thanks for the feedback on the split screen. We had removed it based on feedback by other uses (causing issue with touches near the tops and bottoms). Perhaps that is a way we can allow users to switch between the two modes. Also, I agree with you on the pitch bend as well. Do you imagine it would be one control for all keys?

### 5/5 — Great app for microtonal midi control

*2024-02-17*

Hi! Thank you so much for creating and continuing to support this app! The only feature request I have is that we be able to number the individual buttons manually so that saving a preset is even more beneficial, especially when working with hyper chromatic scales.

**Developer response:** Thanks for the review. I presume you want to "number" the notes with a midi value rather than use an isomorphic layout?

### 5/5 — Musix Pro

*2023-12-29*

I have had this app for several years, and always come back to it and learn something new.  I particularly like the many keyboard options which are isomorphic, and use Janko and Wicki-Hayden everyday, while toying with the B and C systems from time to time.  It's been great ti practice for my "real" keyboard (Striso midi controller) and my acoustic Hayden Duet Concertina.  It's a treasure!

**Developer response:** Thanks for the kind review. Musix Pro is a labour of love, and we hope to put add some minor improvements the near future.

### 2/5 — Almost there

*2023-12-25*

The App with the layout and customization is awesome. Sadly missing auv3 support or even IAA is more than a missed opportunity. These things are basically standards nowadays. Network midi does work on synth apps in standalone but not with AUM.
I really hope this will get added soon to bring this gorgeous app up to todays standards.
Cheers

### 5/5 — 🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨

*2023-12-15*

Thank you for this this app it’s so amazing, Anyone looking at this thinking about purchasing it, just buy it you won’t regret it… It comes highly recommended. 👍🏼👍🏼👌🏼

### 5/5 — Best midi controller on the App Store!

*2023-12-12*

I love this thing! Best midi controller and isomorphic one too.

### 4/5 — Isomorphic

*2023-08-04*

This lets you try linnstrument, lumatone, wicki, janko, regular tuned fretboards, accordion, and custom square or rectangle or hex layouts. Being fascinated with these layouts, this app is a killer app for tablets and worth twice the price, in my opinion.

Unfortunately, not enough people share this view and development stopped years ago. The UI is clunky, documentation, unfinished, the feedback tool calls it a beta, theres interapp audio but not audio units, and no mpe or bending/sliding/glide. Midi over lan works great, but between two ipads i had missed notes. I havent tried it in AUM yet.

All that said, this is the app to buy if youre curious about isomorphic interfaces but arent ready to drop 1 to 2 thousand dollars, order 3d printed janko keys, or retune your guitar. I think the app notional keyboard has square layouts and mpe but not hex, and is twice the price but updated.

**Developer response:** Thanks for the honest review Jason. You are correct in that there is soo much more we would love to do with Musix Pro, but unfortunately, the market is much too small for us to earn much more than coffee money. Hopefully one day we have the time to improve it into the app that our users and the instrument deserve.
