void compute_sample ( void )

Run the step function on each of the voices. Sum their outputs to get a 12-bit sample, and put the sample in the queue. If the queue is full, then hang onto the sample to try to enqueue it again next time.

void timer_interrupt ( void )

The timer interrupt takes audio samples from the queue and feeds them to the 12-bit DAC. If there is a queue underrun, it turns on the LED briefly but visibly.
