Orangutan plays Gershwin...or not

[Jim Remington]

Nice work! I noticed that the Pololu music routines for the X2 also use only one timer, based on the same idea.

Now, if there were an easy way to generate a music array from an arbitrary tune,
life would be even better. Maybe just scan in a score? Finally, we need polyphonic output for our robots!

I totally agree. That midi-decompiling program you found is great, and the source file I used to generate the note array only had three tracks. I'm really tempted to wire up two more buzzers...

Adam:
Try this (it is more suitable for the range of buzzer pitch)

OCR1A=(pgm_read_word(tune_index)>>2);//read note frequency and transpose up two octaves

Still seem to be a few flaky notes, but well worth the effort!

Finally, you do a divide by zero (OCR1A) at the end of the tune. I wonder what happens then?

Just stumbled on this, it really makes you appreciate the power of modern computers and microcontrollers to do all sorts of things, from factoring primes to playing Baa Baa Black Sheep:

Hi, I just wanted to mention in this thread that our new play() function and the handy get_free_ram() function are included in the C/C++ libraries that we released this week, in case you want to try them out.
