I always assumed that tempo-delays and thinsg would just ask the host for
the musical time at the start of each buffer. With sample-accurate events,
the host can change tempo even within a buffer.  If a plugin is concerned
with muscial time, perhaps it should ask for the musical time at the start
and end of the buffer.  If the musical time stamp the plugin wants is within
the buffer, it can then find it and act.

This breaks down, though when the host can do a transport mid-buffer, and
sample-accuracy permits that.  Perhaps plugins that care about musical time
should receive events on their 'tempo' control.  Tempo changes then become
easy.  Transports are still smarmy.  Is it sane to say 'don't do a transport
mid-buffer' to the host developers?
