title: How to reproduce C64-like sounds?
body: <p>I did some of my own research and found out that SID-chips had only few hardware supported synthesizing features. Including three audio oscillators with four possible waveforms (sawtooth, triangle, pulse, noise), with ADSR envelopes and ring modulators. Accompanied with oscillator sync and ring modulators. Also read there was a way to play single PCM sound as well.</p>
  
  <p>It is all so little, but still I heard lots of different sounds from my TV sets. How were they combined to produce all that variety of audio?</p>
  
  <p>To give some specifics, I'd like to know how to combine those components to produce guitar, piano or drum -like audio? Another interesting things would be different buzzes and sounds specific to C64.</p>
