calculate (musical time elapsed from now to next tempo change or end of

subtract musical time elapsed in this calculation from element's
remaining delta

This algorithm will suffer some roundoff error, potentially losing or
gaining a tick on every audio processing frame. If you tell me that 1 tick
of error doesn't count, I'll gladly forward every bug report from our
customers that complain when their hear a "comb filter" effect between
rendered soft synth tracks and their live counterparts. ;-)
OK, seriously, I'm trying to understand how to actually implement a plugin
this way. I need to stew on it for a few minutes.
But then again, this discussion is about *requirements*. Does GMPI require
musical time conversion anywhere on the time line? If not in version 1,
maybe in some later version. If in some later version, why not in version
1, so Ron and Todor can shut up?<g>
