I don’t quite understand how different divisors can influence the timbre. Do you mean that the internal waveforms (SAW, PWM, SUB) somehow react differently to different dividers? Or are they still synchronized with each other? It sounds like several waveforms are out of phase. Or something like formant shift ))

I mean the timbre in the area when the frequency after portamento has stabilized. The note frequency is exactly the same as without portamento. I don’t understand how different dividers can affect the timbre itself if the oscillator reproduces exactly the same frequency. But something about the sound is clearly different.
I'd need to test this myself, but, I would wager that my description of this effect as "interference" is a good description from my memory. Likewise with the effects at high notes. There is "an effect", but, the reasons for it can't be so easily determined based upon the available evidence of recordings or the output alone.

Ideally we'd have the inner workings of the chip via de-potting or de-capping the IC. Even then, it would take a massive amount of work to identify all the circuits and there would be very little certainty at a glance.
