The Ether Pad app is a innovative Android app for making relaxing music. It has a simple user interface with the menu on top and the notes below, that occupy most of the screen. There are a lot of options to this app and it also has multi-touch capabilities. There also are settings like the octave, scale, key, sound and an about section. You can change the octave from -2 up to 2, the scale from the default to: blues, major, minor, pentatonic, flamenco, chromatic, whole-tone, octatonic and Bohlen-Pierce. All the keys can be used, the size can be set from 4 to 14 keys on display and there are three voices you can choose from: Eather Pad, Distorted Dreams and Xanpalamin. This app allows you to play over the songs you already have playing and if you have a screen recorder with internal sound recording, you can make recordings. The Eather pad is a great music tool, considering the unique sounds that it produces, you cannot have such a creative control on this kind of music without a touchscreen interface. That is why I think that the Ether Pad app its place very well on a smartphone or tablet, on which it works the same way, the screen size does not matter in this case.
