+
+The makefile for this collection is configured for Linux only - Linux binaries included.
+
+Each external has a demonstration Pd patch (*.pd) associated with it.
+
+Source contents:
+
+polygate~ - switch between multiple signal inputs - variable fade rate both linear & equal power
+
+shuffle - a no-repeat random generator - outputs numbers within a set range
+
+pan~ - equal power stereo panning
+
+system - sends a system message to the console
+
+ln~ - natural log + inverse
+
+rec2pol~ - convert rectangular coordinates to polar eg. can be used to
+ convert sine & cosine rfft~ output to phase & magnitude
+
+pol2rec~ - inverse of rec2pol~
+
+getenv - Sends value of an environment variable argument on bang.
+ Use a 'set <NAME>' message to reset the variable name.
+
+
+two other related patches:
+
+polvoc.pd - example of pol2rec~ etc
+
