It is designed to make roll drills more enjoyable for banjo pickers, especially as compared to metronome work, by playing the roll for you while you practice, either with or without a rhythm section and metronome beat. The screen displays your choice of 12 common rolls in tablature, and when you click start, you will hear the roll at your selected speed, with each note in the tab highlighted at the moment it should be struck.
Jiri tells us that necessity was the mother of invention in this case.
“I’m a banjo player myself, and I couldn’t find an application or any interactive tool for help practicing banjo rolls, so I got an idea to create it itself.
Practicing with a metronome isn’t fun, so I said myself that it would be better to play with accurate background music, and hear how the rolls should sound.”
Other features include:
- Variable metronome speed
- Speed up feature that will increase the speed after a user-selectable number of repetitions of each roll
- Volume of banjo, bass, guitar and metronome can be adjusted or turned off
- Playback can be set for G, C, or D chords, or changing from one to the other

This video does use the actual audio as it shows some of the optional settings.
