The audio *can* respond to control changes mid-block, if the control
information is derived from Pd's clock (e.g. with metro, pipe, del)
and if the audio object does handle it, which for example [vline~]
does. 

See attached.

Ciao

#X text 395 105 Thus \, time is not quantized for messages triggered
by clocks \, i.e. initiated by metro \, delay \, qlist \, etc. \, although
it is for ui-triggered messages. It is up to tilde objects to do some
extra work and respect the "now".;
#X text 398 41 Pd has a subsample-accurate notion of "now". When a
clock-delayed message is served \, the "now" is set to the exact time
stamp assigned to a clock-serving method in the clock queue.;
#X text 396 177 vline~ does this extra work.;
