For anyone who's interested: This is a crappy little DOS program that I wrote a couple of years ago (that amazingly appeared on my computer somehow...) that will play perfect-pitch notes via your computer's built-in speaker. The user inputs the note and the octave, and the program does the rest. Really lame, but it's good for n00bs to learn C++ with.
Like many of my other projects, I'll post a DL link as soon as I find a file host...
