//################################### frog.dsp #####################################
// A simple smart phone abstract instrument than can be controlled using the touch
// screen and the accelerometers of the device.
//
// ## `SmartKeyboard` Use Strategy
//
// The idea here is to use the `SmartKeyboard` interface as an X/Y control pad by just
// creating one keyboard with on key and by retrieving the X and Y position on that single
// key using the `x` and `y` standard parameters. Keyboard mode is deactivated so that
// the color of the pad doesn't change when it is pressed.
//
// ## Compilation Instructions
//
// This Faust code will compile fine with any of the standard Faust targets. However
// it was specifically designed to be used with `faust2smartkeyb`. For best results,
// we recommend to use the following parameters to compile it:
//
// ```
// faust2smartkeyb [-ios/-android] frog.dsp
// ```
//
