Music 171 homework 1
This assignment is to make a Pd patch that produces two sine waves. They should be tuned a musical fourth apart (tempered or perfect fourths are OK), for instance at 220 and 293-1/3 Hz. Use another low-frequency sinusoid to control their amplitudes so that, together, the two pitches fade in and out once every second.

Your successful patch should sound like this. It should not sound like this .

For extra credit, see if you can make the two sinusoids fade in and out in turns, so that the second one is loudest just when the first one is faded out, and vice versa, so that it sounds like this.
