Response from developer

Hi jacki, Glad you like the app. Good catch. Thank you. This will be fixed in the next update. Regards, John

Great app

It’s no frills, easy and quick.
I wish it could play the tones bump I’m ok with it not doing so.
It hard to find an app that teaches you mode that won’t change the core root note or make you dive into a menu to change mode.

Thanks! You guys get it!
