//Envelopes allow you to shape the sound. The basic idea is that a sound has the following shape
// Attack: This is how long it takes to fade up to maximum volume
// Decay: This is how long it takes to reach the sustain level.
// Sustain: This is the sustain level
// Release: This is how long it takes to fade out.
#include "maximilian.h"

int CurrentCount;//
double myOscOutput,myCurrentVolume;//
maxiEnv myEnvelope;
void setup() {//some inits
//Timing is in ms
myEnvelope.setAttack(0);
myEnvelope.setDecay(1); // Needs to be at least 1
myEnvelope.setSustain(1);

//notice that we feed in a value of 1. to create an envelope shape we can apply later.

// This is because there is only one outcome if the statement is true.
