 Yes & no. Samples ported from other machines (ibms are the best) sound
better than samples made with a 64 sampler. I think it has to do with the
64's power supply for one thing (noisy).

 I've done this, sure you can play 12 bit samples if you like, but there is
a terrible 4khz tone behind it all, and the quality
improvement is negligable. Although one advantage of this is that you could
have 3 different samples playing simultaneously on each SID channel, but
I'd hate to program it..
 The way the pulse waveform technique works is that you put on a square
wave of the highest frequency you can, and change the pulse width (ie
change the ratio of on to off of the square wave). This gives the
'illusion' of a change in volume.
 This is the way messy-dos machines play samples on their built-in speaker,
as it is binary (ie either on or off).
