ok i spoke too soon. it looks like it was super easy to address both
these concerns (duration => loopEnd causing a total stop, and
playback depending on loop points when not in loop mode) and i've got
fixes in the next version. hopefully i didn't break anything else!
and also, hopefully nobody has grown dependent on the earlier non-
