Yes, this lack of introspection is a significant obstacle. It was a huge PITA to figure out what parameters of various DSSI synths were available and how to control them. I ended up having to use write/adapt an OSC sniffer (http://restivo.org/projects/oscsniff) in order to figure out WTF was going on between the GUI and the synths.
