Help with modwheel minimum value in z3ta+ 2?

Hi all, I'm learning z3ta+ 2 and am trying to learn the modulation matrix. I have setup a simple patch with a saw wave. I'm trying to use the modwheel to start from the original pitch of a note and go up an octave. In the modulation matrix I have:

[Source: Osc 1] [Range: Full] [Control: Modwheel] [Destination: Osc 1 Pitch]

Edit: What I'm getting at, is that the mod wheel seems to start out lower than the original value, completely silent, and works up to it at the top of the wheel, when the entire "range" is covered.

... The modwheel only plays the original sound of the note at the top of the wheel. It does not go higher than that pitch. How can I correctly set this up to where the first note, at the bottom of the modwheel, is the original value of the parameter? Thanks for any help, sorry of this description is confusing but the way this is setup seems backwards from a traditional modwheel routing. Just trying to get a handle on how this works.
