#X text 22 303 The gain value is a simple multiplier to the output
value of the slider and determines the maximum linear gain output regardless
of the scaling mode. For example \, "2" will output the double of the

it checks the DSP state and loads the GUI accordingly \, where the

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!;
