Addendum.
I just downloaded the trial version of the HOFA software and, as a post earlier stated, it looks (to me, anyway) like it does everything that I need. The price is more than I wanted, but I think I'll buy it.
One question I do have is this: is it worth it to buy the plug-in version that can be used within the DAW (HOFA states that they have tested it with an array of DAWs, including Sonar), or to go with the stand-alone.
I'm using the stand-alone trial version now.
Thanks in advance for your comments.
