So it knows how to calculate the exact position in quanta of any
event, after taking into account tempo changes. So every meter
event simply contains a duration, which is the delta in time
before the host is going to send the next meter event.
Why can't a meter event just set a property that sticks until
another, different meter event occurs? This is how e.g. SMF works.
IOW, why is the duration span needed? I'm assuming this is
independent of tempo changes.
My idea here was to give the plugin a way to know the tempo over the
next interval.
I'm confused. Are you talking about tempo or meter or both? Tempo
-- the speed of the pulse -- is (traditionally, at least, and with
appropriate handling of changes in the denominator) orthogonal to
meter -- the way beats are counted and the number of beats per bar,
which defines where barlines fall.
