Sample Size and Sample Rate
These are not editing parameters. They're put on this page to give you a convenient place to
check the size in Kilobytes of the current sample, and the rate at which it was sampled.
TRIM
The TRIM page lets you set the Start, Alt, Loop, and End points of the current sample. The top
line tells you whether you're editing a ROM or RAM sample, and indicates the zoom setting. At
the left of the display is the Gain (display magnification) setting. This Gain setting doesn't
affect the amplitude of the sample, just the view in the display.
In the diagram below, the sample points are expressed in individual sample elements. Pressing
the Units soft button (or the Quick Access mode button) will display them in seconds.

The four parameters on this page are Start (S), Alternative Start (A), Loop (L), and End (E).
Selecting these parameters and adjusting their values enables you to modify how the sample
plays back when notes are triggered.
There are four vertical lines that indicate the settings of the four parameters. You'll see all four
lines only if the values for each of the four parameters are different; otherwise, the lines will
overlap. Selecting one of the parameters will move the line corresponding to that parameter to
the center of the display, where it will flash to indicate the parameter's position. The line
corresponding to the currently selected parameter will flash. Turning the Alpha Wheel will
move the sample waveform relative to the line. The line remains in the center of the display,
and the waveform shifts to indicate the new position of the point. You can also use the
alphanumeric buttonpad to enter new values directly. Press the ENTER button to register the
values you enter.
The Start (S) point determines the beginning of the current sample. You can truncate the
beginning of the sample by increasing the value of the Start (S) 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 RAM samples below zero, but if you want to add silence at the
beginning of a RAM sample to create a delay, you can use the Insert Zero DSP function to add
as much silence as you like. The start points of ROM samples can be set lower than zero (you
can set negative numbers for the Start (S) and Alt (A) parameters). Doing this will cause
portions of other samples to be played, which can create interesting effects.
Note that for RAM samples, you won't see any waveforms displayed to the left of the Start
point, but you will for ROM samples.
The Alt (A) parameter lets you set a second, optional start or end point for the current sample.
The Alt will be used when the Alt Switch parameter on the KEYMAP page is set to On, or when
it's set to a specific 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 Alt
