The TOD string is routed to the input of a Serialize Date symbol, which formats the
string as specified by the <format> parameter. The value of 4d will format the string as:
month/day/year.
The resulting formatted <date$> string is routed to a Make String Permanent symbol
with a Permanent String Size parameter of 50d (50 characters). It is also connected tothe

Note that in addition to the Date, the Source_Text string being routed to the source
selection text field is also connected to the Make String Permanent symbol.
Volume
The Volume Up and Volume Down buttons are programmed using an Analog Ramp
symbol, which is another symbol that generates a smoothly transitioning analog output,
rather than a stepped output like the Analog Initialize.
When the user presses the Up or Down button, this will ramp the volume level up or
down until the button is released, or until it reaches 100% (or 0%). The <ramp_time>
parameter specifies the time it takes to ramp the volume from 0% to 100% (and vice
versa). The volume mute button is attached to the <mute> input, which will mute the
audio (cutting it immediately to 0% ) for as long as that input is high.
The analog output of the Analog Ramp symbol is routed to the volume input of the CNX-
PAD8A to adjust the volume of the currently selected source.
