Sets the bar in such apps too high
Absolute gem. If only life was this good all the time. Doesn’t matter what skill level you are at, this is a must have app for anyone interested in learning or expanding their musical prowess. At $7.99, it’s a steal. Kudos to the developer of this app. On a scale of between one and five stars, I’d give it ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️. Edit on May 9, 2025 - The only small nitpicking I have with this app is the color scheme of the app itself. Black font on teal background on different options is extremely hard on my aging eyes. Other than that, the app is still a grand slam. 😊 Thanks for this wonderful app.

Great App Feature Suggestion
Alright, so I have just started using tonality for chord generation in AUM and I gotta say I really like the simplicity and use for this feature. There is still so much for me to explore within the app. However, with the features I’ve tried so far, I do have one feature suggestion for the chord and scale note generators in this apps chord auv3. So, I have found it a bit frustrating that every time I switch the key my chords or notes are playing in on my pads that it causes my midi mappings to be reset. If there were an ability to simply set global midi mappings on pads within an instance of the auv3 version of the app that would be amazing! Overall, great product, do recommend so far, I would really enjoy this feature thing for streamlining my workflow! Thanks!
