#X text 47 501 Patches using send~/receive~ or throw~/catch~ to intercommunicate
must have the same blocking -- and if their parents are blocked bigger
than they are \, there might be wierdness.;
#X text 45 420 If using send~ or delwrite~ from a switched-off patch
\, the output of corresponding receive~ and delread~ objects in other
\, running patches will cycle old input (and sound like garbage). Throw~
may be switched with impunity \, but not catch~.;
#X text 43 92 Switch~ \, in addition \, allows you to switch DSP on
and off for the window. All subwindows are also switched. (If a subwindow
of a switched window is also switched \, both switches must be on for
the subwindow's audio DSP to run. Pd's global DSP must also be on.)

#X text 44 269 Pd's default block size is 64 samples.;
