Amazing app, but...

This app is great. I love the Standard add on. However, when writing progressions, I am unable to add a pickup note. When I make a blank measure at the beginning with beat 4 having a chord, the drum AI treats that 4th beat as the first one, and it throws the rest of the song off. Also, in the complete map I’m unable to find 9 chords. Thanks!

Finally ready for prime time

I’ve had this app for quite a while but hadn’t used it ... earlier versions seemed to me to be brilliant and intriguing but also frustrating. The core functionality was obscured by bad UX/UI. I stuck with iRealPro which is more modest in its aspirations and simpler to use. I don’t want to interrupt my practice time to monkey with an app. The harmony map is a cool idea but I don’t find much use for it.

Finally, MTH has matured to the point it’s really usable, especially if you buy the 1000 jazz tunes in xml format and import them.

The developers are responsive to comments. I’m sure further refinements are continuing.

I’d recommend this for any serious student of music, either classical or jazz-based, or any player who wants to deepen their understanding of tonal harmony.

Exporting backing tracks as MIDI creates amazing options. You can make a backing track in MTH and export it to your DAW to orchestrate it, or export it to MuseScore and see/edit it as a score, to use the backing track as a basis for a band arrangement!

A forum to share user-created backing tracks would be a killer addition.

Maybe the developer could be persuaded to create a companion app: mapping atonal harmony pro!

Great idea, egregious execution

I don’t write many reviews, but couldn’t hold back here. An expensive and highly aspiring application which should never have been released to the public without sufficient beta testing. Not only is the UI laborious and non intuitive, but the program is incredibly buggy seemingly without any effort from the developer to address obvious concerns. One basic example would be that the program does not automatically open selected items. Rather, the user is forced to manually close a a screen view before he/she can work with a selected item, ie. song file in a portion of the program/different screen view. Screen icons are tiny and unintuitive as well. It really is too bad because the program would be a fantastic teaching tool if not for the horrendous UI, essentially rendering the app useless.
