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.

W-AIR MIDI is a midi enabled app which sends and receives MIDI messages and is designed to be a companion app for the BOSS Waza Air Headphones as well as midi capable foot pedals and controllers. Via the use of midi messages, the app can select/retrieve presets, adjust and toggle effects, and adjust some of the effects settings. The app provides a full touch interface as well as mapping of midi CC codes to most controls for midi controller or foot pedal use. Specific features include: - Preset selection which retrieves the preset and displays the preset's effects state and levels - Gauges for Boost, Mod, Fx, Delay 1, Delay 2, Reverb, and Ambience with level change (slider under the gauge) or on/off toggle (tapping the gauge) - Each effect displays the active effect colour and name, and tapping this will cycle through the three effects (green, red, yellow) - The effect assignment to each colour block can be swapped from the list of effects via the swap icon to the left of the effect colour block - Some effects settings are exposed and can be edited via the levels icon to the right of the effect colour block - Tap tempo can be set with a slider or tap for both delay 1 and delay 2, showing both BPM and millisecond intervals. The tap tempo also has a copy and half value copy feature between the two tap tempos - Faders for Gain and Volume control - Noise Gate setting - Preset EQ, Bass, Mid, Treble, and Global EQ settings - Selector switches for Amp Selector, Gyro Selector, Sound Selector, and Cabinet - Battery level indicator - Tuner - Decoupling of Fx/Delay and Mod/Boost so that all effects can be used simultaneously - Allows preset settings to be saved (including name updates) as well as exported and imported - Assignable Midi CC codes for most controls via a Midi learn mode feature (when activated, the app listens for incoming CC code and shows that code in the learned code box, simply tap the gauge or slider you wish to assign that code to). - Midi CC mapped controls can be used to select presets, toggle effects on/off, cycle through the effect block/colour, open effects settings, move faders (with an expression pedal or volume knob) and the same CC code can be assigned to more than one control when appropriate (i.e. one button to toggle the Fx and Boost at the same time) - Assigned CC codes are preserved as user settings and recalled when restarting the app and can also be exported to file and imported from file - Supports landscape, portrait, as well as split view - The screen is zoomable with pinch gesture. This is useful for Split View and resizing the Split View of this app to fit the screen - A bluetooth device discovery page is available from within the app (to view/select the connection state of the headphones and any midi bluetooth pedals detected) This app is not meant or intended to replace the official BOSS BTS app, it simply exposes some of the most common settings that would be adjusted while playing. Note that the BTS app does not need to be running to use this app (in fact it is best if it isn't to avoid conflicting messaging).

Verdict
The clearest difference is rating: W at 5.0 against Musix Pro's 4.6. W also leads on review sentiment (100% vs 78%). Musix Pro's advantage is ratings volume (136 vs 9) and iOS requirement (13.2 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.
