Razo, I don't know if this will help you, but my first concern with the V-synths was how tiny the windows were on my 27" iMac.  By reading through archived forums, I found a cure:  use the accessibility preferences to employ keyboard zoom, which zooms in the entire desktop, including the V-synth window.  Doesn't work that well, but it's way better than trying to work with those tiny V-synth windows.
