it’ll track correctly regardless of what your oscillator is tuned to. If you take, say, the Marbles major scale setting, feed it into a an oscillator set up with its root - ie, the pitch with no voltage added - at say, an E flat… it’ll spit out major scales on E flat.
That is: the Marbles factory scales all start from a lowest note of 0V, and then go up from there (ie, repeating every whole volt, because a volt is an octave). If you sum that voltage with whatever the internal CV of the oscillator is (ie, the position of the coarse + fine tune knobs)… it’ll add the right intervals to the root note, and you get a scale.
Add that output to B half-flat… yup, you’ll get a B half-flat major scale, and so on.
Really, the key thing is that the unpatched oscillator is at what you consider the root of the scale you’d like it to play in is. Then, quantise to that scale. A scale is just an array of intervals.
There is no ‘correct’ or assumed tuning across modular; tune your oscillators root (with no input) to whatever you want, and voltages applied to a V/Oct input will correctly offset them.
I am aware this is not always as intuitive as I tend to think it is.
