object. Any subwindows of this window can also be switched off here.
If a patch and a superpatch both have switches \, both must be "on"
for DSP to run in the patch.;
#X text 32 203 switch~ takes optional arguments the same as block~.
If you supply arguments to switch \, the patch will be switched AND
reblocked.;
#X text 31 258 Only one switch~ or block~ may appear in any window.

than your superpatch. This is useful for writing FFT based patches
(see the "fft examples" tutorial series.);

64 If you want to reblock audio computation \, do so in a sub-patch
and keep the adc~ and dac~ objects in a super-patch. Also \, you can't
send~ or receive~ between windows with different block sizes or overlapping.
Only the inlet~ and outlet~ objects know how to reblock signals. In
this example \, you could put a dac~ in this \, outer window \, or
in the switched subwindow \, but not the blocked one.;
