Detailed Description

Represents a single band-limited oscillator with multiple waveforms.

Before using

Set the sample rate using setSampleRate() and set the oscillator's parameters using setParams().

To use

• Call setFrequency() to set the oscillator's frequency.
• Call nextSample() to compute the oscillator's next sample.

‍This class is loosely based on code from the JX10 synthesizer by Matthijs Hollemans.
