The web is full of metronome sites, but most just let you set a tempo – basically what a traditional metronome would do. There’s more functionality that you could wish for though! How about an automatic speed trainer that increases the tempo according to a pattern you decide?
Best Drum Trainer lets you set start and end tempos, as well as the total time and the time for each step. Missing parameters, such as the number of steps or the tempo increase for each step i calculated automatically.
Once you’ve created a pattern it gets its own URL so you can easily save it or share it.
