Drum accompaniment 與 Groovebox - Retro Drum Machine 使用情況與統計

Features: 1. Configurable BPM(beats per minute). 2. There are 4 default bit patterns: - POP/ROCK - HIP-HOP - HARD-ROCK - FUNK 3. You can choose a theme for the drum pads. 4. Can be used by infants and older kids as a toy, because I implemented multi-touch and 99% of clickable elements are drum tiles, so a kid will rarely interrupt the music by a random touch.
