+The "audio playpen" is intended as a collection of analog-style modules
+for people who just want to patch stuff together without worrying much
+about how Pd works.  A fair amount of work would be needed to make this into
+a more usable package than it is now.  At the moment it's unclear what
+should be the relationship between this collection, the "examples," and
+the "tools".
+
+At the very least there should be oscillators and envelope generators here,
+and audio-rate db/rms/dB, mtof, ftom conversion...
