there is no mechanism in pd, that allows you to check, whether a certain
argument for an abstraction was specified or not. when a certain
argument is not given, pd just assumes '0'. if '0' is not part of your
intended argument range, you can check in your abstraction, if the
argument is '0' and assume, when it is '0', that it was not specified.
[list $1] <- allows both, symbols and floats
[53 ] | <- your default value (could also be a symbol)
