Digital Processing 125
Truncation shortens a sample's length by trimming off individual
samples from the beginning and/or end. Truncation is most often used to
remove unneeded portions of a sample to conserve memory, but it can
also be used to change instrument characteristics such as removing the
attack from a plucked string note or isolating a particular section of a
sample.
1. Activate Digital Processing module.
2. Select Submodule 3.
3. Truncate the desired amount of samples from the start on line
two and/or the end on line three, then press ENTER.

Start: 0.00 00001
End: 2.43 53610
Size: 2.43 53610
The sample size equals the difference in samples between the start and
end points. Because of this, these settings interact with the size value on
line four in these ways:
• Truncating the Start will cause the size to change to maintain a
constant End Point.
• Truncating the End will cause the size to change to maintain a
constant Start Point.
4. If you are not satisfied with the resulting truncation, or want to
compare before and after, proceed to Digital Processing, 9.
Undo.
Portions of a sample can be cut, copied, and pasted to other samples, or
the samples from which they came. The Copy function allows you to
duplicate a section of a sample, and store that duplicate in a special part
of memory called the clipboard. For more information see the section
Background: Cut, Copy, Paste, and Undo.

The left and right cursor keys will
change the start and end points so that they
fall on positive zero-crossing points in the
waveform.
