== SID Internal Architecture ==
From an interview with Bob Yannes, the designer of the SID . [http://www.ffd2.com/fridge/meow/docs/SID.primer Source].
It's pretty brute-force, I didn't have time to be elegant. Each "voice" consisted of an Oscillator, a Waveform Generator, a Waveform Selector, a Waveform D/A converter, a Multiplying D/A converter for amplitude control and an Envelope Generator for modulation. The analog output of each voice could be sent through a Multimode Analog Filter or bypass the filter and a final Multiplying D/A converter provided overall manual volume control.
