The Undulating Noise Machine
The undulating noise machine comes with 2 modules. A player which loops samples of white, pink and brown noise (the sound at the same speed as the resting human heart rate (60 bpm) ). The second module allows you to create an ambience by adding effects and rhythmic motions by simply drawing a motion on the dedicated pad. Unfortunately, there is no record feature, despite this I will rate it as a Killer App, because of its great UI and for the fun that you have in creating an ambience.
