So, Digitone has

- Wavefolding (sometimes known as a sine shaper) by setting an operator to 0hz, and then modulating that with the waveform you want to fold.

The SY77/99 do this, the original DX7 *didn’t* because it’s minimum operator frequency was something like 1Hz?

The OPSix looks like it has this, so 1-1

- The Digitone lets you sweep some kind of harmonics knob, in order to get what the video maker said was “wavetable-y sounds”...didn’t we see similar things in the OPSix manual? Why yes, we did:

GAIN
Adjusts the strength of the Wave Folder effect. Increasing this value will increase the number of times that the waveform is folded.
OSC MIX (OSC Mix Level)
Sets the oscillator level inputted into the Wave Folder.
BIAS
Applies a DC offset to the input signal to change the harmonics.

So it’s 2-2.

Finally, I can’t ignore the fact that the OPSix has more base waveform types (INCLUDING NOISE S/H which does crazy things when you add a little of it as a modulator) and 2 more operators...

So OPSix wins 3-2.

Man, my DX7, which is currently leant up against a wall (not enough keyboard stands or space!) is now looking at me, sadly.

I don’t use it that much and I could get a real good price for it to put towards an OPSix, but it’s so classic and beautiful...I think I’ll save it for the future if I move to a bigger place (if work ever gives me a raise & we all survive this pandemic!)
