A free app for Android, by keuwlsoft.

In the Music Pad app, you can make music by sliding up and down the beams of a multi-part instrument. You can also create different musical sounds by changing the pitch of the notes. It allows you to create your own music and share it with your friends.

This app also has a built-in equalizer that allows you to customize the sound to your preference.

Music Pad supports 53 octaves and gives you a wide range of musical sounds. You can choose from four different instruments, each with a different sound. You can also choose to play in perfect fifths, perfect fourths, or whatever note you want. The pitch slider allows you to increase the pitch smoothly between two notes without changing the note.
