Rapture Newbie sad Question

Hi!
I find Rapture to be a cool sounding synth, and I specially like the patches that play melodic loops. I think it is one Raptures coolest features.
 
I have the following issue: When I try to edit the melodic loop in any of these patches, using Raptures envelope tool, i find myself struggling to drag the envelope shape at exactly the right pitch so the musical patern wil play in tune. The UI is too small and it is almost impossible..
 
My Question: Is there a fuction that I don't know about which grids the envelope to semitones increments? If this is not the case I think the Rapture designers have made a bad decision not to incorporate this into the synths set of tools. I think many of us listend to the cool melodic sequences present in Rapture's patches and tried to modifie them to fit our songs, but finally gave up trying because the UI is not friendly enough to permit this. This has for effect that the cool sequeceneced sounds never get used because there is no way to incorporate them in actual song because their melodies are fixed... If there was a way to easily change the notes (i.e. having a grid option) in the patches, people would go crazy creating cool ideas and Rapture would become the coolest thing... But as it is, it is useles.. It is, to me, just another sad case of waisted potential and work, due to a small stupid detail...
 
P.S. I do not own Rapture Pro, does Rapture Pro's new features include a semi-tone grid in the envelope UI? If this is the case i will go buy it instantly!
