Well, I was thinking to start from the beginning, assuming the probability that I did something incorrectly and therefore asked for directions either to doc or forum elsewhere. Perhaps I should have been more complete in my question.
905133 - There is no user guide that deals with connecting the STPAD 16 to CWSonar. In general, I'd class the Synido documentation as more of a feature list than a how-to. As you mention above, there is no mention of it in the forums.
What I have so far is Synido recognized as a MIDI device under Edit/Preferences...I can add a new MIDI track that recognizes the Synido. However, after I activate the input echo to "Auto Thru" I hear nothing when striking the pad. The meter however does show input. Further, recording the track at this point does register input proportional to velocity.
Let me know if you need more.
Thanks.
