Pd is a real-time graphical programming environment for audio and
graphical processing. It resembles the Max/MSP system but is much
simpler and more portable; also Pd has two features not (yet) showing
up in Max/MSP: first, via Mark Dank's GEM package, Pd can be used
for simultaneous computer animation and computer audio. Second, an
experimental facility is provided for defining and accessing data
structures.
