What do people say about Musix Pro?

"Anyone who loves music, regardless of skill level, owes it to themselves to experience Musix. Simply exploring the app will open musical doors you never knew existed." -

"Musix is a Killer App!" -

See Musix Pro in action:

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


- 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.


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.

So Close to 5 Stars.

I am overjoyed that a high-quality isomorphic keyboard app exists in the iOS ecosystem. Musix is responsive, well-designed, and thoroughly usable as a serious musical instrument given its fantastic support for MIDI, OSC, and AudioBus.

In my opinion, this app is 3 minor changes away from perfection:

- Please let me disable the "slide" between notes! The iPad touchscreen is great, but it is far too easy to mistakenly hit a second key after beginning a touch event. I don't slide between keys on a piano, I don't really ever want to do that here either!

- Musix needs a blank coloring. Blank white keys are my favorite way to play on isomorphic keyboard layouts. The rainbow coloring is distracting, and the major scale colorings are constraining for musical thought.

- I want to turn the lettering off. All that text is just unnecessary and distracting to me as I don't really think in terms of lettered notes.

Thank you so much to shiverware for making such a phenomenal tool! I recommend it to everybody who will listen.

Thanks for the great feedback. Text can be turned off from the #b menu. Choose Text -> None. You can turn most colors off (other than tonic) by choosing Mode -> Chromatic and Note Pattern -> Default. As for fully disabling slide/colors, we may add this to our feature list. Seems like a solid suggestion.

An ergonomic revolution!

Having not so large hands, I have always struggled with the reaches involved in playing the piano keyboard, and have always wondered if there was a better way to lay out the keys. This app really opened my eyes to the possibilities of the isomorphic layout, especially the Gerhard layout. The efficiency in space reduction is significant, as I am able to access 4 chromatic octaves’ worth of hexagonal keys on an iPad Pro 12.9”. I do realize that some of these layouts have existed before on concertinas and button accordions, but this app gives you a lot more options. It also allows you to turn the iPad into both controller and sound producer - one neat little package you can take anywhere!

A few things I would suggest to make this app even more awesome would be to mirror-image the screen, because many layouts favor one hand or the other, in terms of performance proficiency. Velocity control could help with expressive performances. A pitch bend bar option would also aid that. As a person who likes tactile feedback, making Musix Pro able to control the layout of a hardware button controller would make it indispensable. That being said, this app is a fundamentally important tool in the evolution of musical instrument design. Thank you, Shiverware!

Thanks for the kind words JDRock. We are working on the ability to have two different layouts on the screen just for the reasons we describe. Hopefully some of the new chording features, quick layout changes, and octave changes have improved your experience as well as we try to find time for all the other improvements we have planned.

Essential for Linnstrument Owners

This fantastic app is the reason I got an iPad Pro and might be one of the most impactful musical tools I've encountered in my life. As an owner of a Linnstrument, I wanted to have as much practice time as possible on an isomorphic grid, but the Linnstrument can't go everywhere I go. This app *greatly* accelerated my skills playing on a grid and has transformed my understanding of music theory. As I spend more time with it I realize how much of a window into isomorphic or hexagonal layouts it is -- anyone else using this app: Do yourself a favor while you're learning, and switch between 1) layouts, 2) scales, 3) button sizes, and 3) labellings every now and then, even if you're working towards other goals. Doing this really opens up the possibilities but also constantly keeps you at the "edge" of where your learning is at, which helps you get better faster. Going back to a Linnstrument after playing on this app is an amusing sensation, as playing on a glass surfaced iPad requires a lot more mental agility so when you return to the Linnstrument you feel like an ultra-precise master. Great app :)

Thanks your thoughts. We are very happy that you are squeezing all the isomorphicism out of the app!
