getnamed	object-name [symbol]	In left inlet: The word getnamed, followed by a symbol which specifies the name of an sfplay~ object, interrogates the named sfplay~ object and reports the number of channels, sample size, sample rate, file length in milliseconds, sample type, and filename out its outlets.
open	filename [symbol]	The word open, followed by a name of an audio file, opens the file if it exists in Max's search path.
