I love this app!
I love this app. The most basic use is just to improve the speed of your rolls (it has a speed up option - you can tell it to speed up x bpms every y bars) but you can also put in your own chord sequence so it's really good for practising chord changes of a song or soloing on top of the banjo rolls. I even use it for scale practice - it makes it slightly more interesting... Yep. Well worth it!
