If we can use MIDI and stil play in sync with other musicians
then surely a START command can be propagated to wherever it
needs to arrive with acceptable delay.

Pro tape decks could start in a few tens of ms at most. That
was perfectly acceptable. And surely we can do better than
that.

Only pre-filling play buffers when a START command arrives is against
all rules of sane RT design. Even when your disk systems are very fast.
And it's easy enough to do it right.

And yes, some bloated GUI systems can be sluggish but if you want
your app to be responsive (e.g. for visual editing) you'll have to
do something about that anyway. Nor should it be assumed that a
START command is always given by a mouse click.
