Real sinusoid vs complex sinusoid example:

::

	signal SineReal {
		default:	0.0
		rate:		AudioRate
		reset:		MasterReset
		meta:		'A Sine wave at 1000Hz'
	}

	Oscillator (
		type:			'Sine'
		amplitude:		1.0
		frequency:		1000.0
		phase:			0.0
		reset:			off
	)
	>> SineReal;
	
::

	signal SineComplex {
		default:	[0.0, 0.0]
		rate:		AudioRate
		reset:		MasterReset
		meta:		'A complex sinusoid at 1000Hz'
	}

	CxOscillator (
		amplitude:		1.0
		frequency:		1000.0
		phase:			0.0
		reset:			off
	)
	>> SineComplex;

	
A real sinusoid built from two complex sinusoids:
	
::

	complex ComplexSinusoid [2] {
		default:	[0.0, 0.0]
		rate:		AudioRate
		reset:		MasterReset
		meta:		'Sum of two complex sinusoids'	
	}
	
	CxOscillator (
		amplitude:	0.5
		frequency:	[1000.0, -1000.0]
		phase:		[-90.0, 90.0]
		reset:		off
	)
	>> ComplexSinusoid;

	# Use complex oscillators to produce a sine wave
	ComplexSinusoid
	>> CxAdd()
	>> CxReal()
	>> RealSinusiod;
