#X text 25 460 This is a looping sampler in which you specify the number
of loops per second (the frequency) and the size of the chunk to loop.
If the frequency is less than about 20 \, you will hear repetition
and the chunk size will sound like transposition. For frequencies above
50 or so \, you hear a tone whose timbre is controlled by the chunk
size (best kept below 5 or so.) Remember to use the "shift" key on
number boxes to make fine adjustments.;

#X text 23 597 In this patch you will frequently hear discontinuities
at the looping point. If you're working in a studio \, you can sometimes
find "good" loop points for samples. Another approach \, better for
live situations \, is shown in the next patch.;
