the zero point of the display (the horizontal line in the middle of the waveform display.) Though

adjusting these points visually is helpful, always listen to the sample and make the nal settings

based on what sounds best. You’ll notice an audible click in your sample loop if the ends of the

waveform do not meet where the loop occurs. The closer you can get the two ends of the

waveform, the better the sound quality of your loop will be. Using zero-crossings for the Loop

and End parameters may also help reduce clicks at the loop point, see Zero- and Zero+ below for

parameter had a lower value will have a value of zero the next time it is loaded (values for all other sample

point parameters will be adjusted relatively.) Trimmed portions after the Alternative Start (A) or End (E)

points (whichever has a higher value) will be lost upon saving. If you wish to save a copy of the original

Zoom- and Zoom+

These buttons increase or decrease the resolution of the waveform display, enabling you to see a

larger or smaller segment of the waveform of the currently selected sample. The top line of the

display indicates the zoom position in terms of a fraction—for example, 1/256—which indicates

These buttons increase or decrease the magnication of the currently displayed sample

waveform, enabling you to see the waveform in greater or lesser detail. At the left of the display,

you’ll see the magnication setting, which is expressed in dB units. You can adjust the

magnication from 48 dB (maximum magnication) to 0 dB. This doesn’t aect the actual

amplitude of the sample, only the magnication of its display.

The simplest way to think of the Zoom and Gain buttons is to remember that the Zoom buttons

control the left/right magnication of the waveform, while the Gain buttons control the up/

down magnication. Neither button has any aect on the sound of the sample. You’ll often use

the Zoom and Gain soft buttons together to focus in on a particular sample segment, then

magnify it to see it in close detail.

zero-crossing. A zero-crossing is a point where the sample waveform is neither positive or

negative (crossing the horizontal line in the middle of the waveform display.) The currently

selected parameter (Start (S), Alternative Start (A), Loop (L), or End (E)) will be set to this point in

the sample. Setting these parameters to zero-crossings can help minimize clicks at the start, end,

or loop point of a sample. It’s best to have each of these points set rst by adjusting each

parameter and listening to the sample, then if needed search for a nearby zero-crossing.
