Ratings and Reviews
Excruciating
Can't figure out how to play a simple backing track. There are links to videos but none explain the basics of how to use the software. All I wanted it for was to be able to set out backing tracks, but a few hours after downloading have abandoned. Seems like there's a lot of potential but it has the worst interface I've seen on an app for a long while. No instructions. Poor.
After finally figuring out how to access the progressions, I then find the option screen to change tempo etc refuses to close. Tried re-arranging my desktop, tried clicking everywhere, hitting escape etc. Ended up having to force stop the whole app to close one preferences window!
App really needs work.
Developer Response ,
I am sorry you couldn’t figure out how to load the progressions. It is probably because the app does not include them. You can download 1000 Jazz Standards Progressions online please go to https://tonalharmonyprogressions.wordpress.com/2018/10/01/mapping-tonal-harmony-pro-progressions-book-1-jazz/
(You can also access this webpage from within the app if you click on the Import button or the Open button and then on the Download Free Progressions Online button)
The webpage explains step by step how to download them and import them.
To load a progression just use the Open button to launch the catalogue and choose the song you want to play by just clicking on it.
Hope that helps, and please consider updating your review if you find the app useful.
The complete manual is accesible in the help menu item in the app.
blows your mind
Have had this app for years, intially for the ipad and then I got the desktop version. Has been great for free updates. If you want to muck about and click on different chords in the harmony map is it fun and also gives you a chance to play with 'home' and 'away' sounds. Can't say I have yet really worked out the interface yet - it is a bit complicated and not that intuative - that would be my only criticism of it.
Not as described
This business has videos on its YouTube channel showing functionality that the current version does not have.It was so imporessive that I bought, only to discover that it's pretty useless
