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. ### 4/5 — Very Cool *2020-12-19* Would be extra cool if it allows playing triad by pressing at a point where three keys come together. You know what I mean? ### 4/5 — Need dark theme note pattern coloring *2020-09-15* Personally I feel it will be more fantastic if there is a color theme, where the keys are all in dark colors, while I touch it, it will be bright color. Kind of similar to the colors of those launchpad style app. Also for the existing color themes, it will be cool if touching the key triggers bright color or even some twinkling/flash effect instead of black as it is now. **Developer response:** Thanks for your review. We do recognize that the built-in audio synthesis has its shortcomings. Please connect it to one of the other amazing midi synths out there for an awesome experience. ### 4/5 — So Close to 5 Stars. *2020-06-26* 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. **Developer response:** 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. ### 4/5 — great app, easy to use *2020-02-05* makes it easy to lay down some bass or keys that sound great. support is quick and responsive too. thanks again, looking forward to future updates. ### 5/5 — The Innovation string players have been waiting for. *2019-11-27* The boards are laid out in a way that makes them fun and surprisingly ez to play. It just all seems to click together really well to make an outstanding instrument. I far prefer this to traditional linear keyboards. I know I’m not the only string player who understands the concept of a linear keyboard but doesn’t enjoy rocking one because something doesn’t mesh. Personally I think in terms of circles musically and this app gives me the extra dimensional aspect to provide me with circles to look at. This app makes my iPad feel less like a sequencer and more like a traditional instrument. It’s I pretty neat controller that way, but the real power behind this app is that it is literally a sort of archetype or template for every song you could ever want to write. This is hands down the writers most powerful tool, even if you’re a writer that has your theory memorized or well understood there is certainly going to be an idea that this app can help you inspire to write. This isn’t the one to be cheap about 10 bucks on. This app is very innovative and should be funded along to enrich our musical / technical foundation in this growing industry/ hobby market. If you mad it doesn’t have its own sounds, don’t be, this isn’t that sort of design. Sounds are dime a dozen. This is a whole new keyboard concept where your finger shape positioning never needs to change to create new chords, this makes arpeggiating and chord progression a cake walk to navigate thru manually even at faster tempos rt on your iPad screen. It’s awesome ¡ These devs are fast at responding if you need even the stupidest help like I did too. I’m really excited about this app and that’s why I’m giving the best review I can. Im hoping to see continued development over the course of my lifetime on this one... DONT OUTDATE MY KEYBOARD PLZ !!!!!!! ### 5/5 — Great dev great support *2019-09-02* Had an issue. Dev helped 5 Stars from me! **Developer response:** Please ensure you turn on Background Audio on your synth (audio producing apps). Please let me know if there are still issues after this. ### 5/5 — Essential for Linnstrument Owners *2019-03-23* 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 :) **Developer response:** Thanks your thoughts. We are very happy that you are squeezing all the isomorphicism out of the app! ### 5/5 — Great for learning *2018-11-25* Great for learning music theory and bridging the gap between how something sounds and how it works according theory. Highly recommend it to visual thinkers. Really fun for improv as well. I would like to see an option to put a subtle outline around the octaves, I think it would help me to relate it to playing piano a little more easily. **Developer response:** I'm glad you are seeing the advantage of using Musix Pro. Thanks for the octave marking suggestion. There is an option to "Show Parallelogram" in the systems many (sharp/flat/natural icon). It shows all the notes within one octave to give you an idea of the octave shape, but I do like the idea of a more "playable" separation of octaves. I will add it to our future ideas list. ### 3/5 — Vollschuss *2018-09-10* Im Ofen. Mindestens. **Developer response:** Hello, I would love to understand the issues you have had and improve Musix Pro for you. I do not speak German (and google translate does not make sense for the short answer that was left). Would you mind emailing support@shiverware.com with a longer review? ### 5/5 — An ergonomic revolution! *2018-08-17* 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! **Developer response:** 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. ### 5/5 — Great! *2018-08-06* Simple customisable layout, easy to remember patterns for scales & chords. Really like how you can move the range of notes up and down using the corner controls. Changing the size of the keys is also an excellent feature to enable it to be set up for individual playing styles. No problems with getting the midi out to control other apps **Developer response:** I'm glad you are enjoying all the work we have put into this app. We look forward to taking it to the next level very soon. ### 5/5 — great! *2018-08-02, version 2.3.2* very nice for Janko fans. Would be nice if we could create our own color patterns. ## Most critical reviews (10 lowest-rated) ### 1/5 — To many issues *2020-04-24* The app keeps freezing and it doesn’t show how to change instruments **Developer response:** Hi Navi, Can you email support@shiverware.com so we can help? We need some information (such as device, etc) to gain insight into why you are seeing "freezing". To change instruments, just tap on the Guitar Icon, then Tap on the blue text under Internal (which shows your current setting). Also, make sure that the Internal switch is turned on. ### 1/5 — Waste of money *2019-08-17* I can’t hear the sounds of other apps. I can’t hear any other sounds from different apps **Developer response:** I am sorry you are having issues. I believe you have a configuration issue with your setup, please email info@shiverware.com so we can help figure it out for you. ### 1/5 — Useless without velocity *2014-09-22* Wish I'd done a bit more research before I pressed buy. I really like the isometric layout and think it could be a really great tool, but without velocity it's useless for me. Especially since the velocity it does output seems to be 100% making everything I run midi to sound like it's being smacked with sledgehammer. Even if there was a static option to set velocity at say 50% or 75%, that'd be be better. But surely these creative designers can think of some way to integrate a smart velocity control. **Developer response:** Hi MattyEss, we have since "pulled back" the standard velocity to prevent sledgehammering. ### 1/5 — aucun intéret *2013-08-25* c'est une honte! Faire payer si cher pour çà!! ### 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? ### 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 ### 2/5 — False advertising *2016-12-14* All features work great but in the iPhone version midi out to daw is not supported. There is no mention of this in the description. Only reason I bought it. A very expensive app for limited functionality merits 2 stars in my book. I suggest thumbjam if you're looking for a midi controller with scales **Developer response:** Hello, Midi out to daw is supported if your daw can accept standard midi signals. What type of setup do you have? ### 2/5 — Epic? *2015-02-21* More like epically underwhelming. Spend your money on something else **Developer response:** Hi Borts, How did the application fail to meet your expectations? ### 2/5 — Needs a piano *2013-04-05, version 2.1.1* Great app for exploring music theory but It is in desperate need of one real instrument, like a piano! Spacefart synths have there place and im not saying get rid of them! but it's really hard to hear/learn any valuable note relationships with bright brass, hi pass sirens, long decays, pitch mods and other effects.... Side note this app should partner with tenorion ### 2/5 — Rip off *2013-02-20* 9bucks to add the features that almost every other dev has added for free in the last year, namely midi and audiobus. Feel well ripped off. ## Most praised reviews (10 highest-rated) ### 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 ### 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. ### 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. ### 5/5 — Good in it’s day *2023-01-04* Needs to be updated to MPE to be current. ### 5/5 — El teclado isomórphico perfecto *2022-03-20, version 2.4.1* Lo uso para controlar aplicaciones standalone y audiobus, y ofrece suficiente configurabilidad para cubrir casi todo lo que necesites. Agradezco mucho que tiene support para multitasking ### 5/5 — Great! *2021-12-31, version 2.4.1* Fantastic midi controller. Flexible. Wish it had pitch and mod wheels but otherwise fantastic! ### 5/5 — A real instrument *2020-12-11* First music app I’ve seen that seems like a real instrument in its own right optimized for the iPhone. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
