Adjust model update during recording or writing a new wave file. Formerly we were using the model's completion percentage to indicate write proportion and completion -- that's not a good idea because some layers will reasonably avoid rendering at all until a model reaches 100% completion (it's supposed to report only progress on the initial model generation, and the model shouldn't change during completion updates).
