+#X text 20 58 log~ is useful for generating curves from line~. In the
+example below \, log~ with an argument 2 (for log to the base 2) is
+used to generate a pitch glissando and a logarithmic amplitude envelope.
+;
+#X text 58 194 optional argument determines the base of the logarithm.
+If no argument is present \, e (the natural logarithm) is used. base
+can be changed via right inlet.;

+#X text 467 200 try different bases...the lower the base (above 1)
+the bigger the output. bases between 0 and 1 result in a negative output.
