John Bowen Synth Design

Trying to recreate this patch on the solaris, it should be possible probably but am not getting the desired sound.
Help would be appreciated, I think am not patching the modulation correctly.

here is what I did :

OSC1 Type MM1 Ramp, shape 50, coarse 5, Mixer 1 & filter open --> Source 1 OSC1, Amount 100, Control Joy X, Str 100%, Dest Pitch
--> Source 2 OSC3, Amount 120, Control Off, Str 100%, Dest Pitch
OSC3 Type MM1 Ramp, shape 50 not send to mixer --> Source 1 OSC3, Amount 100, Control Joy Y, Dest Pitch

Been testing a bit more

this is the closest I get :

OSC1 Type MM1 Ramp, shape 50, coarse 5, Mixer 1 & filter open --> Source 1 OSC3, Amount -120, Control Joy X, Str 0%, Dest Pitch
OSC3 Type MM1 Ramp, shape 50 not send to mixer --> Source 1 Joy Y, Amount -102, Control Off, Dest Pitch

I have to move the joystick from left to right and can't go too low with the joystick to prevent harsh fm sound, but am almost there !
Input still appreciated on how to get closer
