Hi RAM,
Switch the "VCO-2 Range switch" from "Normal to Low"
According to my understanding then:
When you do this, then VCO-2 work like a LFO, and you won't get normal sound but only the sound the LFO produce at the set speed/ the VCO-2 range and tune settings. For instance in 16' range setting you hear clicks if you have the mix turned fully to VCO-2.
If you let VCO-2 CROSS modulate VCO-1 and mix to only having VCO-1 sound, then you in this setting hear the LFO modulation from VCO-2 affect VCO-1.
If you then also use a normal LFO to affect VCO-1 using the VCO MODULATOR, then you actually have two different LFO modulations affecting VCO-1.
The VCO MODULATOR use the normal LFO settings and not on the VCO-2 low setting.
So when you do this
Adjust the "VCO MODULATOR LFO Slider" all the way up^
It has no effect if you have sound or not in your example. One can say it affect or should affect VCO-2 LFO rate when VCO-2 is set to work as a LFO. But the affect is not audioble to me. Perhaps there is a bug in this missing modulation possibility. If the normal LFO did affect the VCO-2 LFO then you could create more complex modulations. That i think should be possible as you can select if the normal LFO shall affect VCO-2 or not. So i would say if it's not a bug, then i would like this feature.
BTW - How do Arturias Jupiter emulations sound relative to the original? And how did the "mimic" work?
Best
