There is good news and bad news. The bad news first. The household
synthesizer you are trying to use has not been ported to the new Opus
platform for UrbanSim, and we have not decided whether to port this
application or try to build on another existing application, like the
one SEMCOG has created, or the one developed for the Atlanta Regional
Commission. As a result, we really can't support this application right
now. The good news is that there are now several synthesizers out there,
so hopefully we can provide a robust synthesizer before too long. If
anyone wants to volunteer effort towards this, they would be welcome.
