About this app
Randomly generate practice drum scores with various themes and levels. You can try difficult phrases little by little.
Themes are added whenever the app's developer feels like practicing.
The app's name is an abbreviation of the Japanese title "Ore no Doramu Renshucho!" (My Drum Practice Notebook!), and it was named after one of my favorite radio programs.
[Theme]
- Jazz basic
Practice to be able to freely hit the snare drum and bass drum while playing basic Jazz patterns with the ride cymbal and foot hi-hat.
- Combination of S.D. and B.D.
Practice the combination of hands and feet by hitting the snare with 16th notes and filling in the gaps with the bass drum.
[How to use]
- The score screen
A phrase is generated and displayed according to the set theme and level. The time is 4/4. At startup, the phrase displayed last time is displayed. When you press the "generate" button, the phrase will be regenerated and displayed.
- The parameter settings screen
Choose a theme and level.
- The app settings screen
It can be displayed from the "Menu" button on the score screen. Various settings can be changed.
* Number of bars per line : Specify the number of measures per line. If you reduce it, the generated phrase will be too long to display when you return to the score screen, so please regenerate it.
