This is not an app to play music with a virtual keyboard but a synthesizer to create sound effects. All elements of a sound: volume, frequency, low-pass and hi-pass filters cutoff frequencies can be modulated in time by creating envelopes with an intuitive drag and drop interface.

The app starts with the "time" view. There you can adjust the "time points", i.e the points in time where some change will happen to your sound. In the other screen you set up - point by point - the volume, frequency and filter characteristics of your sound. Choose one of the 8 available base waveform, click on "play" and listen to the sound effect you've created!

If you find it hard to generate interesting effects, you can find inspiration from a full range of 15 presets. The sounds you create can then be saved in wav format and used everywhere in your smartphone.
