no, but there are a *lot* of things that plugins, particularly
instrument plugins, might want to do that are based on musical time or
even just transport time. the free-running sample count time is
irrelevant for many things. when you ask a plugin to start the release
phase of a note off at a certain time, its often not based on the
sample count but on musical time. if you stretch the tempo while the
note sounds, it should still start the release phase when it reaches
the correct musical time, not some arbitrary sample count.
i will be talking more about this issue at the LAD meeting in
karlsruhe (plug, plug :)
