#X text 38 485 Click the message boxes above to try it. Note that in
the first two boxes \, the line~ objects get two messages. The first
one \, with no time value \, causes the line~ to jump immediately to
the value. The third box takes line~'s previous value as a point of
departure. What you see will depend on which box you last clicked and
how long you waited between the two.;
#X text 662 727 updated for Pd version 0.33;
#X text 41 600 On most machines \, you will hear an interruption in
the sound one second after you click on the first or third box. This
is because the graphical updates are likely to eat more CPU time than
your audio buffer has pre-buffered for. You can avoid this if you keep
your graphs in sub-windows and open them only when you need them. In
some future version of Pd this behavior will be improved. Until then
\, you'll have to avoid having arrays getting re-drawn during music
performances.;
