#X text 118 503 Here is the previous patch modified to use two copies
of the sample reader \, 180 degrees out of phase. The second sawtooth
signal is derived from the first one by adding a constant (0.5) and
wrapping the result to fit again between zero and one. The result is
the "phase2" signal.;
#X text 119 584 The computation of "chunk-size-samples" (as a message)
and "read-pt" (an audio signal) is the same for both copies and is
separated out at top left. At top right is the same loop frequency
calculation as before.;
#X text 120 654 Finally \, the two copies' outputs are added and the
result sent to the audio output.;
