Great samples, awful user interface

The developer offers great samples, appealing voicing/chords and very nice percussion sounds but the goodness ends there because the whole program is just not ready to accomplish its full potential. The user interface, its functionality and ease of use are way, and I mean way below par. It’s a great app if you just want to play along but if you push it to write your own stuff in a simple concise manner, this app will be exceedingly frustrating. Expensive too if you buy the Real Book.

Awesome and not so awesome...

This app offers one a remarkable visualization of cadence. And It’s an excellent way to rapidly analyze jazz standards. And though a supremely valuable tool for music education, I find it frustrating to use for other purposes. I’d like to recommend this app for both, play-along practice and composition, but shortcomings of the UI make these frustrating experiences. The transport, tempo, key change, bar-repeat controls are dinky and often buried in menu folders making play-along unnecessarily difficult to manage. The map appears to be a wonderful tool for composition. But it seems to be missing chord audition and undo/redo functionality (Auto-save would be very useful too.). One really needs a piano or guitar and pen and paper to audition chords and record chord changes in order to avoid unraveling composition with a few poorly executed choices via UI. I open the app on two devices at once. I use MTH as a sketch pad on my iPad and I record my final decisions on MTH on my iPhone when I don’t have access to a piano keyboard. Am I missing some useful information here? This is no good. So, five stars for active visualization (Bravo). But sorry to say, I’m still leaning on other apps for play-along and composition. MTH is so very close to ideal. Keep it coming, please.

So much potential but..

There is so much depth in this app and the quality of the player audio is better than the other app I use regularly. But the user interface is dreadful. Things you need to press all the time are tiny and hard to find. Large chunks of the screen are wasted on things that I don’t want to see and I often can’t figure out how to get popovers and menus to go away. Things you need to access frequently are squirreled in deep menus and I feel like I need new glasses just to use this app. The UI should just be redone completely with a focus on common use cases. Ironically I saw an ad for this app and clicked through only to realize that I had purchased it years ago and gave up on it then. I had forgotten about it and decided to give it another chance. My main feeling when I’m using it is just confusion. I’m sorry to be negative about something that is a labor of love for someone - it’s just very idiosyncratic and arcane to me.
