The Fatback System app for iPhone and iPad

Have you ever heard of the "Fatback System" by Gary Chaffee?

If not, heres a quick definition:
"The Gary Chaffee Fatback System combines over 200 bass drum combinations with a static backbeat on 2 and 4, with a 1/4 to 1/16 rate in a 4/4 time signature."

In a nutshell, practicing these exercises will help you develop superlative bass drum control and freedom while playing a static backbeat.

If you have are together with a bass player (or you are a bass player and you are with a drummer), you have the opportunity to add a bass stave. Practicing together will help you to lock in really tight and create amazing and interesting grooves.
You even have the chance to create random bass patterns. This way, both of you have to concentrate even more and your timing and feel of subdivisions will improve enormously.

Features in this app:
- Three difficulty levels

- Accented HiHat patterns
- Random HiHat patterns for every quarter note beat
- Static HiHat patterns selectable

- Random Kick Patterns for beat 1 & 3
- Random Backbeat Patterns for beat 2 & 4
