How to use Mozzi

The guts of a Mozzi sketch

// This includes Mozzi's core functions, which are the small set in this sketch
#include <MozziGuts.h>

// CONTROL_RATE is #defined rather than being a constant, because Oscils (Mozzi oscillators) run
// faster in tests when initialised with a literal value rather than a constant.  Maybe something 
// to do with the compiler optimising for size rather than speed?  It's a power of two (minimum 64)
// because of the way Oscils have been coded for speed.
#define CONTROL_RATE 64 	// or some other power of 2

void setup() {
// This starts the timers for audio and control interrupts.  Audio is fixed at 16384 Hz.
	StartMozzi(CONTROL_RATE);
}

void loop() {
// This fills the audio buffer.  Don't need to do anything special here.
	audioHook();
}

// You need both of the following functions or your sketch won't compile.

int updateAudio() {
	// Your audio code which returns an int between -244 and 243.
	// Actually, a char is fine.
    // This is called 16384 times a second, so the code here needs to be efficient!
}

void updateControl() {
	// Your control code.  Do as much as you can here, rather than in updateAudio().
}
