Music using the stamp
It doesn't appear through my reading of the forum subjects that many people are attempting or having any success at playing music with the bs2.
After finally getting an amplifier tuned in and working satisfactorily, I am now ready to put some tunes through it.
I read somewhere that the bs2 can play only two notes at a time. Does this mean 2 frequencies in the FREQOUT command is the only way to get 2 notes
simultaneously, or is there another way to actually play the two distinct frequencies simultaneously?
I tried two FREQOUT commands with outputs to two separate I/O points (executed one right after the other) but this only slowed the playback time by half.
Do I need to say "the heck with it" and buy a propeller chip? Or, is there an easy way to build a module that will play many notes at once?

A Propeller would be much better for playing music. It's fast enough to generate multiple tones simultaneously with one cog and you have 8 cogs to work with.
But for a certain disipline.
(8 bit chiptunes)
The PWMpal shines
4 oscillators (tone control via duty cycle)
with 4 (or more) pins for external envelope

You can get more chords using more than one Stamp.
The Basic Stamp Supercomputer with 12 stamps can play 24 notes at the same time.
You could use 2 stamps, or the SoundPal is another way to stir up some extra notes.
