#X text 34 474 In this patch we can loop in any "window" of the input
sample. The "read point" (0-100) gives the starting point of the window
and "chunk" is its size (both in 100ths of a second.) Try \, for example
\, frequency 4 \, sharpness 10 \, chunk size 25 \, and vary the read
point from -25 to 100 \, listening to the result.;

#X text 37 574 You should hear some doppler shift as you change the
read point. To see why \, click on "graph table index" and quickly
start changing the read point--- you should see entertaining pictures
in "table-index". The next patch shows how to prevent this if you wish
to.;
