Hi: I just purchased both the DSF expansion pack for Dimension pro, and the GPO4. I have questions on both and would appreciate your help. First, on the DSF pack titled "Vocal Expressions," I just noticed that there is one preset or program missing. I went to the folder named: "Vocal Ensembles" and hit enter on a program named "expressive choir." When I did that, I got a message saying that the program was not found. Has anybody else experienced this? I just want to know if there is something I have not done correctly, or if I should call CakeWalk or DSF to get help. Then, on the GPO4, I went to the Voices or Vocals folder, I don't remember the correct name, but I found only one preset. Is that right? What I did was to go to the first "empty" with the JAWS curser and left clicked. That gave me a menue of about three or four choices one of which gives you the folders with the presets in them. Is that the correct way? Is there a way to get to any of the parameters?
