+#X text 425 153 This is a classic rotating-tape-head style pitch shifter
+using the vd~ variable delay object. Ther are two moving tape heads
+\, each of which is loudest at the middle of its trajectory \, and
+enveloped out at the moment it has to jump back (or forward) to start
+another scratch. Most of the brain work is in computing how fast the
+tape heads have to move to get the desired transposition.;
+#X text 425 272 The "window size" is the total trajectory of the read
+points in the delay line \, in milliseconds. The delay times are controlled
+by a phasor~ object. The second delay time \, 180 degrees out of phase
+from the first one \, is computed using the "wrap" object.;

+from the first one \, is computed using the "wrap" object.;
+#X text 422 454 The cos~ objects compute the fadein and fadeout of
+the two delay line outputs. They each traverse the positive half of
+the cosine waveform (phase -0.25 to +0.25) over the time the phase
+goes from one end to the other.;
