Are you a Pro Musician who wants the best MIDI playing surface or a music newcomer who wants to play melodies more intuitively? Musix Pro packs more notes on the screen than any other app and does so with customizable layouts that bake music theory in. Step up your musical abilities by downloading now. 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." - 148apps.com "Musix is a Killer App!" - apps4idevices.com See Musix Pro in action: http://www.youtube.com/shiverware 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.

Verdict
The clearest difference is price: AudioKit Digital D1 Synth at Free against Musix Pro's $9.99. AudioKit Digital D1 Synth also leads on ratings volume (2.1K vs 136) and update cadence (every 3 weeks vs every 6 weeks). Musix Pro's advantage is in-app purchases (none vs 6) and ads (none vs shown). On rating, review sentiment and iOS requirement there is nothing between them.

AudioKit Digital D1 Synth is free to download; Musix Pro costs $9.99 up front. AudioKit Digital D1 Synth sells 6 in-app purchases, starting at $4.99 per 7 days. Musix Pro asks for nothing beyond the download.
AudioKit Digital D1 Synth holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: AudioKit Digital D1 Synth has 2.1K ratings behind it against 136, so its average is the more settled of the two. Written reviews complicate that: 78% of Musix Pro's written reviews are positive against 76% of AudioKit Digital D1 Synth's, so the app with the better star average is not the one people write more warmly about.
Musix Pro ships an update every 6 weeks, AudioKit Digital D1 Synth every 3 weeks. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
