-#X text 439 161 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 439 280 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.;
-#X text 437 370 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.;
-#X text 436 462 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.;
