Okay. In this example, the starting four-voiced chord is made of cent sizes (counting from the bottom tone and rounding to the nearest cent) of 401, 702, and 1000 cents. One of the tones is rising gradually and the other three have steady pitches. Because of this, the final intervals of the chord are 401, 726, and 1000 cents.

Hehe. It sounds to me like it's slowing down as it goes, trippy.
There is a point about two-thirds of the way through where it is more
consonant. It would be interesting to check if that's where 1000 cents
and 400 cents are split by a pure 6/5 and a more or less perfect
Noble low minor third. It also not impossible that that is the point
it sounds most consonant to me is only because of familiarity with
that chord. (noble dark third + 6/5 = 600 cents). That would make all
intervals familiar: 400 c., 6/5, Noble m3, encased in 1000 c.
familiar from 12-tET and maybe even a "metastable" interval as well.

What's the registration of this chord? Did you intend
the left channel to be much louder than the right?
Through headphones I hear a beat that slows and stops,
presumably due to critical band effects between combination
tones and original tones. When I play the left channel only
at low volume through a single speaker, the beating is
almost inaudible, even at the beginning of the file.
