Too bad I didn’t have HarmonyWiz so that I could’ve had an even earlier start.” Wolfgang Amadeus Mozart “HarmonyWiz is a great tool for composers like myself. If I had HarmonyWiz when I was a young man, I could have composed a symphony every day.” Ludwig van Beethoven REAL PRAISE FOR HARMONYWIZ: “HarmonyWiz is such a fun and awesome compositional tool! Perfect for helping any musician unlock and explore endless creative harmonic possibilities. It’s practically like having your own digital writing partner at your fingertips. The only problem for Jordan, is that if he keeps this up, he may just “tech” himself right out of a job! John Petrucci (Guitarist of Dream Theater) ABOUT THE CREATORS: Jordan Rudess explains, I always felt that a composer’s thought process would be fascinating to capture in code. I’ve wanted to do an app like this for a long time and, upon meeting developer, Ruben Zilibowitz, it finally has become possible. Ruben has spent years studying classical music texts such as Schoenberg's Theory of Harmony. He started by writing out four-part phrases by hand. Eventually, he was able to translate this process into computer code that could generate natural musical phrases. Through hours of sitting at the piano, studying my own compositional method, to Ruben’s tireless coding we believe we have achieved something truly unique and inspiring.

mTonal is an expressive 24-tone keyboard synth that can be used to smoothly glide across the frequency spectrum, something which is not possible with a regular MIDI keyboard controller. It can send MIDI information to digital audio workstations (DAWs) that support MIDI Polyphonic Expression (MPE), making this app extremely versatile for recording and processing microtonal MIDI data. Record audio files using the synth presets of the app and share them across other apps, email, or social media. BASICS Explore the world of quarter-tone music using this 24-tone keyboard. Blue keys between the white and black keys mark the quarter-tones. Switch between octaves using the octave controls on the upper-right corner of the keyboard. Choose between three keyboard layouts: one octave, two octaves, and seven octaves. The seven-octave layout gives you a wide range of tonal possibilities without taking the size of a grand piano. Use the warning button to clear any unreleased touches in the synth. MIDI FUNCTIONALITY Send MIDI information to various DAWs and software synthesizers that support MPE (MIDI Polyphonic Expression) like Logic Pro, Cubase, and Max/MSP. You have the option of using a wired, Wi-Fi, or Bluetooth MIDI connection, and you can change the connection anytime using the settings button on the upper-left corner of the keyboard. FEATURES Turn on gliding to smoothly transition between two notes and create a microtonal soundscape. Use the cents button to display the note's cents value for precise control over the pitch. Familiarize yourself with the keyboard’s layout using the notes button, which displays the note names on top of the keyboard. For more expressiveness in playing, activate the velocity feature to control note velocity based on the touch size. Hold notes for an extended period of time even after they have been released using the pedal. EFFECTS Apply delay and reverb to customize the sound. These effects only apply to the app's synth presets and will not be sent through MIDI out. RECORD, PLAY, SHARE Record and save your favorite tunes to the iPad. The files are saved in .m4a format. Once recorded, the audio files can be played back in the app. The files can be shared through email, social media, or between other apps. You can also organize your audio files and delete unwanted ones from the iPad to free up space.

Verdict
The clearest difference is in-app purchases: mTonal at none against HarmonyWiz's 5. mTonal also leads on update cadence (fortnightly vs every 3 months) and price ($4.99 vs $9.99). HarmonyWiz's advantage is device support (3 vs 1) and iOS requirement (9.2 vs 13.0). On ads there is nothing between them.
