Viurs Control is only a user interface for the controls on the TI, not for any other synths.
The only way you could control another synth via the knobs on the Virus, is with MIDI. But you`d have to find corresponding CV`s for the controls you want on the JP.

Let`s say the Cutoff parameter on the JP is cv 74, and the cutoff cv on the Virus is 70.
But, the cv for Resonance on the virus is 74, you would control the cutoff on the JP with your reso-knob on the virus via midi.
Usually, or at least as far as i`ve seen on my different synths, these values are not always the same.

I would recommend getting a hold of a Midi Implementation chart for both synths. The way i do it is with automation on my sequencer.
