This is a simple drum pad program optimized for touch screens. [Play mode] Tap the 4 * 4 pad on the left to play the sound assigned to each pad. [Change mode] Press "change button" on the upper right to change mode. You can change the sound by flicking up and down on each pad. You can also cancel sound registration by long-pressing. No sound is assigned to the gray pad. To add a sound, tap the gray pad in "change mode". [Increase the type of sound] To increase the type of sound, open the program and load the sound directly into the sound of the "pad" sprite. No code or database changes are required.
