	rdfs:comment "This is similar to the CSound module 'phaser1'.  It's a series connection of 1 to 30 first order allpass filters with feedback.  For 'Output mix', the range -1 to 0 crossfades between the inverted output and the input, and the range 0 to 1 crossfades between the input and the non-inverted output.  Without feedback, the maximum effect is at +/- 0.5.  For both 'Feedback gain' and 'Output mix', the best polarity depends on whether the number of sections is even or odd." .
