Question about Mother 32 pitch and keyboard

[bvh]

I am looking at getting this one but have a question.

Is there a way to decouple the keyboard from the pitches of the notes being played?

I love the sound of key tracked filter cutoff points and would like to play it (which I know is possible) but I want the underlying note to stay the same, a drone for example - is this possible?

I know there is a VCO control in, but not sure if that actually overrides the internal keyboard or just sends additional KB info?

Like the Mavis, I don't think it's possible to disconnect the KB from influencing the pitch of the oscs.
