#X text 13 596 This patch take the same principle as the earlier "one-shot
sampler" \, but allows you to parametrize sample playback. Since we
must wait 5 msec before starting the playback \, we store all the parameters
in "f" objects \, and recall them to construct the new note. Transposition
is done by altering the amount to play back in the (artificial) ten
thousand seconds (1e+07). The playback segment can be altered to start
in the middle of the sample instead of the beginning \, and you can
change the duration and rise and decay times.;
