How can you make nice tones or sounds on a small speaker connected to one pin? =
Is this possible? Square wave tones are very harse and not very musical. I =
would like to have sounds kind of similar to bleeps and blurps found in Las =
Vegas gambling machines.

And if I were to use say a simple R2R ladder and 8 bits how to create small =
good sounding "tones"?

Richard.
