Well, that seems to be involved somehow. I hadn't used this program in a while and did an upgrade and now it doesn't seem happy any more.
So, yeah, I used a different synth which seemed to fix the original problem and I inserted the synth as a Simple instrument. Now, I can hear it while trying to record by the data itself is not getting captured, so the exact opposite problem, or it records and I can't hear anything while playing. But, it is getting closer! And sometimes I can see the virtual instrument, and sometimes not. Not sure where to toggle that. I guess it's been longer than I thought since I used it last.
