There are three separate parts: a "Grain Synth", a "Filterer", and a "Virtual Mallet".
Each of the parts uses Tab 3 of the "Simple" layout, as well as the accelerometer data from the phone.
Grain Synth controls: Holding the smartphone with the screen up: Tilting left/right controls the grain duration. Tilting forward/back controls the grain trigger frequency. Dragging the dot on the screen left/right crossfades the synth's tone from "ceramic" to "organic". Drigging the dot up/down controls the volume.
Filterer controls: Holding the smartphone with the screen up: Tilting left/right controls filter cutoff of the Pads' lowpass filter. Tilting forward/back controls the resonance of the Pads' lowpass filter. Dragging the dot on the screen left/right moves the Grain Synth sound in the stereo field left/right. Drigging the dot up/down moves the Grain Synth sound in the stereo field forward/back.
Virtual Mallet controls: Holding the phone as though taking a phone call, move your arm down as if striking a bell.
