No, that's three oscillators FMing each other in a ring.

There's also considerable FM, AM, and Bandwidth Mod on some of the filter stages.

With the 261e's you actually have to do a little work to get things that sound like aliasing. :-)

Not with mine.
Even the sine waves alias in mine.
Not for mellow, silky tones, I'd say....
And yet, not nearly as bad as the 259e.
Let's see what my upcoming 259 sounds like.....

I hear some distortion in my 261e sines, but not too much in the way of aliasing, but maybe I'm missing something. Interestingly, the mod osc sounds cleaner to me than the principle osc.

Here's an aiff file of the sines of both sides of one of my 261e's. The left channel is the principle oscillator and the right channel is the mod osc.  They aren't quite sweeping the same, so it sounds a little funky if you listen to both channels at the same time.
