+// This example shows how you can create a basic counter with a phasor.
+// A phasor oscillator can create a ramp between any two values.
+// It takes three inputs - frequency, start value and stop value.
+// These are all double precision floats, so it's a continuous slide.
+// If you write it into an integer, it will round it off for you.
+// This creates a bunch of steps.
