Drum accompaniment 对比 Groovebox - Retro Drum Machine 的使用情况和统计数据

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.
