Sampling and Sample Editing
Editing Samples

If you select the Loop (L) parameter and change its value, youÕll see the segment of the
waveform to the right of the transition point shift its position. If you select the End parameter
and change its value, youÕll see the segment of the waveform to the left of the transition point
shift its position.
When youÕre setting a loop segment for a sample, youÕll want to adjust both the Loop and End
parameters so the two ends of the waveform meet (or come as close as possible) at the
transition point. YouÕll notice an audible click in your sample loop if the ends of the waveform
do not meet at the transition point. The closer you can get the two ends of the waveform, the
better the sound quality of your loop will be. With a bit of experimentation, youÕll develop the
ability to create smooth loop transitions.
YouÕll also want to try to set the loop point at a zero-crossingÑa point where the sample
waveform is neither positive or negative. Pressing the Plus/Minus buttons together will search
(from left to right) for the sampleÕs next zero-crossing. You can usually press these buttons
several times for any given sample without noticeably affecting the sound of the sample. If you
press the Minus button, youÕll reverse the direction of the search, and the next time you press
the Plus/Minus buttons together, the K2vx will search for the next zero-crossing to the left.
Press the Plus button again to search toward the right.
If you adjust the display Gain and Zoom of the sample while on the LOOP page, youÕll notice
that the Gain affects the waveform on both sides of the loop point, while the Zoom affects only
the left side of the page. You canÕt zoom in on the loop transition point in the right half of the
display.
You can also use the crossfade loop (XfadeLoop) DSP function to get a smooth transition
between loop points. As with the TRIM page, youÕll recover memory after saving the sample
and exiting the Sample Editor.
DSP (RAM samples only)
Select the DSP page with the DSP soft button. This gives you access to a long list of non-real
time DSP functions, with which you can modify your RAM samples. The Þrst time you select a
DSP function, youÕll see the Normalize function, shown below. Afterward, the most recently
selected DSP function will appear when you select the DSP page.
All of the DSP functions operate on a segment of the current sample that you select before
executing the function. In most cases, youÕll use the Start and End parameters to deÞne the start
position and end position of the segment you want to modify. There are a few exceptions to this
rule, which will be explained as applicable.
Please keep in mind that the Start and End parameters on the DSP pages are not the same as the
sample Start (S) and End (E) parameters that you set on the TRIM and LOOP pages. When
youÕre working on one of the sample DSP functions, Start and End position refer to the range of
the sample that you want to process. Adjusting these parameters does not affect the overall
