Ah, yes. Sadly I was mistaken.
Concert A is the A above middle C. Using this as a base and exactly equal
exponential steps, my calculator says middle C is
261.6255653005986346778499935233 Hz.
According to Wickapedia, middle C is 261.626 Hz
Another contributing factor to my mistaken belief is that I thought C was
the base of the musical scale and its frequency was always even powers of 2.
That's what you get for living in a digital world.
I won't argue the facts anymore. Just look them up.

James

I don't believe this is correct. Middle c is 278.4375 Hz, from what I
remember, and a quick google yielded several dozen sites saying the same
thing.

No, 440 hz is the A below middle C. Coincidentally, middle C is 512 Hz.

You could simply generate a sine wave at 440hz, which gives you concert A.
now that you have the A above middle C, simply increment and decrement your
frequency appropriately to achieve the desired note.

A rest depends on the beat; it will be one full beat, so a slow
beat will have a longer rest than a fast beat. I usually just
pick seconds; so maybe I want 5 notes per second, which means my
beat is .8 seconds long, so my rest is .8 seconds. A measure
will be 3.2 seconds (4 beats). Each note, then, would be 200
miliseconds, so a quarter note is 50 ms. I hope this makes
sense.
Unfortunately, my note frequencies list has disappeared, but just
Google "musical note frequencies" or something like it. HTH!
Have a great day,
Alex
