Thanks for the links. Unfortunately, they did not help.
Have any other VS700 owners updated to Jamaica Plain? Any issue with the Fantom synth? The synth was working fine last week, and aside from the monthly update, nothing has changed in my setup. So, I'm really not sure what else it could be...
Update: I took another look at the Cakewalk forum posting linked above, and tried the suggestions again. This time, I did get audio from the Synth. I first loaded the Fantom into a new project (as a simple instrument track). The synth seemed to load and it was getting midi input, but it was silent. So I inserted an additional audio track, as per the forum posting, selected Stereo VS-700 Fantom VS as the input for the audio track, turned on input echo -- and suddenly I could hear the Fantom synth. I've never had to do that before. Previously, I would just load the Fantom synth as a simple instrument track like any of my other synths, and it would work fine. That no longer is the case. I'm wondering why...
