Yes I went to that page also and it looks like I will not get and answer from a live person unless I purchase a "premium support" package. I did eventually get the software to work with a pre recorded speech clip that I recorded with voice recorder then used the process button in voxal voice changer to apply an effect. So it seems that part of the programs works but it will just not recognize my microphone.
Voxal Voice changer seems like a good program based on the YouTube videos that I have seen and the number of effects. Included with the program. But why would I pay for "premiums support' for a program that I am using on a trial or free basis when I cannot even get that version to work in the first place.
