e Sample Trim parameters below let you set the Start, Alternative Start, Loop, and End 
points of the current sample. e right side of the top line displays the root number of the 
sample. If the sample is part of a group of sample roots, you can use the Channel/Zone 
buttons to scroll through each sample in the group.
Selecting these parameters and adjusting their values enables you to modify how the 
sample plays back when notes are triggered. Each of these parameter points are expressed in 
individual samples. For example, a one second sample at a sample rate of 44,100Hz would 
have 44,100 values available to adjust for each of these parameters.
Start
e Start point determines the beginning of the current sample. You can truncate the 
beginning of the sample by increasing the value of the Start parameter. You might do this to 
remove silence at the beginning of a sample, or to remove some or all of the attack. You can’t 
decrease the Start point of samples below zero. 
Alternative Start
e Alternative Start parameter lets you set a second, optional start or end point for the 
current sample. e Alternative Start will be used when the Alt Switch parameter on the 
KEYMAP page is set to On, or when it’s set to a specic control source and that control 
source is generating a value of more than +.5. (For example, if you assign MWheel as the 
control source for the Alt Switch parameter, the Alternative Start will be used when the Mod 
Wheel—or whatever control source you have set to send MWheel—is above its halfway 
point.) e Alternative Start can be set before, after, or at the same point as the Start or End.
If you set the Alternative Start after the End, you can extend the play of looped samples. 
Normally, looped samples will play through to the End, then will loop back to the Loop 
point, and continue looping like this until the note is released, when they go into their 
normal release. If the Alternative Start is set after the End, looped samples will loop in the 
same way while notes are sustained. As soon as you release the notes, however, the samples 
will play through to the Alternative Start point before going into release.
Loop
e Loop parameter sets the beginning of the looped portion of the current sample. e 
Loop can be set at any point before the End, including before the Start and Alternative Start. 
If you try to move it after the End, the End will move with it. 
End
e End parameter sets the point at which the current sample will stop playback. Typically 
you’ll use this parameter to trim unwanted silence o the end of a sample, although you can 
use it to shorten a sample as much as you want.
