Detailed Description

SumOfSines -- Sum-of-sines oscillator class

The constructor takes an int format (1, 2, or 3 elements per overtone), the number of partials, and a list of elements

This can cache a wavetable (if you use a strictly harmonic overtone series) or compute a buffer on the fly by summation (slow)

Examples: Format kFrequency = list of values for overtone amplitudes with num = 1, 2, 3..., amps = values, phases = 0 SumOfSines vox(1, 5, 0.2, 0.2, 0.1, 0.1, 0.05) -- first 5 overtones with weights 0.2, 0.2...

Format kFreqAmp = list of values for overtone freq/amplitudes with phases = 0 SumOfSines vox(2, 3, 1, 0.2, 2, 0.1, 3.01, 0.05) -- overtones 1, 2, and 3.01 (i.e., non-harmonic)

Format kFreqAmpPhase = list of values for overtone num/amps/phases SumOfSines vox(3, 3 1.02, 0.2, 0, 2.1, 0.2, 0.1, 3.0, 0.1, 0.05) -- verbose constructor
