Its sounds like multiple notes are playing at the same time - is this true or did you multiplex simultaneous notes somehow?

That's correct; the coil is capable of playing up to three notes at a time. In the Arduino code we effectively OR the PWM of each frequency to create the desired effect. Figure 7 in our report (link in the description) provides a nice illustration.
