for a plugin within the system, there's no point in
caring
about those that are not, except you want it to work as a
sync source. is this what you want?
just imagine two different timelines, one in 6/8, the other in 5/4,
both at different tempos. one delay plugin uses one of them, another
uses the other. neither of these timelines are uniform across the
system, yet plugins with tempo-synced parameters need to care about
(at least one of) them. right?
