That sounds like the ARP synth from Edgar Winter's 'Frankenstein'. This basic preset should get you fairly close (playing A above the open high E string). You'll have to tweak the settings for an exact duplication:
CrazyFun
Mix = WET:50
Pitch Mix = A10+B10
Pitch A = A: UNISON
Pitch B = B: UNISON
Delay A = 10 ms.
Delay B = 20 ms.
(encoder) = HMODLTR / TMP: OFF
Depth / Key = DP: +P5
Speed / Scale = SPD: 70
Xnob = RAMP-DN
Ynob = FBK: 25
(EXP PED Heel) = SPD: 70
(EXP PED Toe) = SPD: 100
In the video, the preset demonstration also adds expression pedal control over the Xnob (waveshape). Over a few tries, I couldn't get changing waveshapes to sound similar to what I was hearing. To me, it sounded like RAMP-DN (sawtooth modulation) all the way.
The Delay A, Delay B, and Ynob (feedback) settings are optional. It sounded a little 'thicker' than 0 ms. I put Depth / Key at a perfect fifth above, but +1OCT is a little steeper. You can use 'negative' intervals, but then the 'GunRays' will be shooting from two different directions.
Another way to approach it would be to set Pitch A & Pitch B up a fifth (or an octave), and have the modulation drift down to your input note pitch ('unison').
