Sorry, we are behind where we'd like to be. The holidays robbed some time, but mostly other things have come up (urgent bugs, support, some very annoying website needs, minor 3.7 features). We've nearly cleared our plates of that junk, leaving a few important 3.6 bugs that need addressing and to finish off audio support. I have plans to see family (I live across the pond) for 2 weeks starting in 4 weeks, which unfortunately could mean another delay. I'd love to say 3.7 can be done before that time and that is what we are shooting for, but I can't say for sure. Worst case it should be done early March.
Do you have a dependency on 3.7? Is there something specific blocking you from using it as is? Remember the audio doesn't have a runtime component
the audio events are just normal events that application code needs to use to play audio. Syncing is also done by application code updating the animations using the audio clock.
