Everything from the pad layouts, scales, new graphics to the sounds work together really well. Also, the new sounds are really, really good (great strings and choir samples). IMHO that this app just quadrupled in value with this free update." - Music-311 "Thanks for such an awesome app, I love that it lets you intuitively visualize and experiment with a "Tonnetz" layout, and better understand Neo-Riemannian theory - as such, Navichord is the perfect gateway from abstract, heady harmony concepts to immediate and practical music being played- a priceless possibility! And it looks beautiful and the tones are great, to boot" - RepentHarlequin73 "This is really a nice, simple, clean app. I love the way you laid out the UI and I especially like that single notes can be tapped first and then dragged seamlessly between notes to produce the chord, then back to another single note if desired. For what it's worth, here are five stars... ***** This app will replace several other more expensive "chord progression lab" apps that I own because I think it's UI design is excellent and perfect for my needs." - ZenLizard "Find using the harmonic grid more intuitive than a piano keyboard, being able to press in the middle of three circles to get major and minor chords is genius. Experimenting with chord patterns and having the chord name at the top and the root and other keys displayed on the keyboard, is helping me get my head around more complex chords." - mister-rz "Downloaded the app when I read about it on dischord. I'm really happy...looks like a great app to explore chord variations." - Jonathan Paran Aran "Read about it on Synthtopia. Bought it just now, love it already. Thanks Denis!" - Dominik Assig "Excelente app para aprender acordes y armonia." - R3dhood "It can definitely be a source of inspiration." - Luca "...it helps (when it comes to chord progressions). It is so simple & that is its value." - Michael L "I use and love Navichord!" - Ep Lipschitz
