1.5.7 released today to fix some of the bugs that arose from 1.5.6. This is not our official October release, and we still anticipate another update this month with some new features, but until then, this latest update should rectify some of the issues that have arisen in the past week.
Cool Jason! I already downloaded to my MacBook (although that didn't seem to have any problems). I'll be updating my desktop PC shortly too. That seemed to freeze with the 1.5.6 update when using the crotales.
