#X text 23 191 First \, if the DSP is on when you load [output~] \,
it checks the DSP state and loads the GUI accordingly \, where the
top right corner shows the status as either "on" or "off". But this
interface also acts as a toggle so you can click on it and change the
status. Another way of doing that in the patch is with the "on" and
"off" messages to the right inlet.;
#X text 227 358 (it behaves as a toggle);
#X text 31 411 Try the above [output~] abstraction as the only object
sending signals to pd's output \, now change the DSP status with the
volume up in one of the usual ways and with the interface provided
by [output~] (via toggle or messages). You'll notice how changing the
DSP status with [output~] does not 'click'! This is because it automatically
fades in and out when turning it on and off!;

and it sends no signal. So \, if you don't want to listen but need
the signal through the outlets \, use the 1st argument or the "dac

Using [output~] without the dac~ is useful for gain adjustments only.
