aPortaDrum is a drumming application designed for Android phone.
(It's now an ADC 2 app)
As long as your phone is with you, you can play the drums whenever you feel the urge, by yourself, or with others. It allows you to play using the phone as an imaginary drumstick.
With two phones, you can even play with a "drumstick" in each hand. Hauling a heavy drum set around is exhausting and inefficient. With aPortaDrum, you have a virtual drum set right in your pocket.
Once the game is started, tap the drumstick icon to start.
Position the phone so that the bass drum is directly in the front.
Tap START to begin.
Hold the phone with the screen facing towards the left. Point the
phone towards a drum. Using the phone like a normal drumstick, strike
the imaginary drum. The phone will produce the sound of the drum that
has just been "struck". The screen will also change color as the sound
is produced, indicating which drum has been hit.
Borrow a friend's phone to enhance the drumming experience. With a phone
in each hand, you can play the drums without a single real drum in sight!
