When I wrote cycle, I meant one audio > cycle, followed by the other one. CPU cycles just don't match up. How about setting up a timer for each wave. Plus mixing both frequencies? E.g. - enable 400 Hz for ~2500 cycles (assuming 1Mhz) - enable 450 Hz for ~2222 cycles So you wait (almost) exactly one wave and then switch to the other one. And then mixing 400Hz and 450Hz e.g. 1:4 to get 440Hz. Have fun!
