PART 2: MANIPULATING THE SAMPLE
Proper use of truncation and looping can conserve memory and create novel effects;
let’s show how it’s done with an example. Suppose you want to sample a long,
sustaining sound such as a gong. Although this will eat up a fair amount of memory,
here are some suggestions.
Compress the gong sound when sampling to even out level variations. This will
help create the smoothest looping effect.
Set a loop after the initial attack of the gong, and loop as short a section of the
sound as possible to conserve memory (see Fig. Appendix-i).
Truncate that portion of’ the sound after the loop end point.
With looping, the sound will have infinite sustain. For a more realistic effect, use
SET-UP function 18 (DECAY/TUNE SELECT) to set the gong for decay. Use the
slider to set an appropriate decay time.
Looping can also provide echo and DDL effects. Loop a complete sound so that it
continually repeats. Then, use SET-UP function 18 to set a decay time; the repeats
will fade out over the decay time. The effect is very similar to echo.
