CAN stop playback

Good app, too bad there is no support. Playback CAN be stopped by touching any chord! Some changes are very nice, some not. Fun to practice soloing.

★★★★★Jun 5, 2015
Cannot stop or pause playback!!

I have to terminate the application to get it to stop playing. Not recommended!!!

★★★★★Mar 2, 2015
Great app

This is a great app to practice with. I play sax and with this app I practice in all keys. Great chord changes too
