Control Voltage output issue

So I’m experiencing an issue when I connect my Little Phatty to my Moog Rogue via Pitch and gate out. I use my LP as a main synth but at times I like to remotely control the Rogue to add a 2nd timbre to the mix, essentially this adds a 3rd/4th oscillator. I use a CV momentary/latching - on/off pedal to add the 2nd timbre when needed. It works very well but…at times I wish to play the keyboards separately. This is where the problem begins.
Both keyboards are in tune(tested) and track at 1 volt/octave(tested). Unfortunately, the note that emits a 0 volt output from the Phatty is different from the 0 volt note on the Rogue. So I have to adjust the Rogues pitch to accommodate for the difference. This creates a transposition of the notes when played remotely from the LP compared to playing the built in keyboard of the Rogue by .5 octaves. Note that they track perfectly together, .5 octaves apart. Does that make sense? I just want to have the option of playing the keyboards simultaneously without having to adjust pitch.
My LP’s 0/0.1 volt output is the note of E. The Rogues 0 volt output is F. Does anyone have suggestions, or has anyone else experienced this as well? I’m assuming that is something that I have to live with but I think it would be cool if I could make an adjustment on the LP’s CV out board. I know you can for the Voltage per octave. But can one transpose the voltage per note?
