Editing Samples - Truncating

The first thing you should do is cut off any excess samples (there is usually quite a lot

at the end) using the Truncate function. The method explained below involves truncating

twice (once for the beginning and once for the end), but it is safer than trying to do this

all at once. After a little practice, this method will come naturally.

Touch the Edit pad to enter the SAMPLE Edit page. Touch the horizontal Zoom ‘+’

pad a few times until you can’t see the start any more, then touch the horizontal

Zoom ‘-’ once . Hold SHIFT and turn the VALUE dial until the highlighted section

starts very close to the beginning of your sample. Touch horizontal Zoom ‘+’ again and

repeat the procedure until the highlighted area starts exactly at the beginning of the

sample, where the wave crosses zero. Touch the Preview pad to make sure . You

can use the ZeroX (zero-crossing) buttons to find the exact start automatically .

Select the Truncate function from the drop-down menu , read the message, then

confirm.

Zoom out completely and press the cursor-down button to highlight the End value .

Touch Preview to check whether there are any unwanted bits at the end. If you have

recorded something you wish to loop in its entirety (e.g. a drum loop), you should

activate the Loop pad to make sure that there isn’t a “hiccup” at the end. Touch the

Preview pad and use the VALUE dial until you can’t hear any unwanted samples. Keep

zooming in and adjusting the end point until you are satisfied. Use the ZeroX

(zero-crossing) buttons. Note: If your sound “fades” to silence (e.g. a cymbal), you

should also use vertical Zoom ‘+’ to make sure you don’t lose the last bit of the “tail”.

When you have finished, select the Truncate function again.

Editing Samples - Finding the Best Loop Points

Depending upon the complexity of a sample e.g. whether it has vibrato or tremolo etc.,

finding good loop points can be difficult. I find the following method very useful:

First of all, search for a section of the wave where the volume remains fairly constant.

Touch the Loop FWD (forward) tab and set the Start and End points to include at

least two of the “humps” which are caused by the cyclic effect. Touch the Loop and

Preview pads so they are both highlighted. Zoom in a little to make sure that the

Start and End points are both at approximately the peak of each “hump”. Keep

alternating between Start and End with the cursor buttons, and touch the ZeroX

buttons until you hear no more clicks.

If you don’t really need anything after the loop, you might be able to save a lot of

memory (in the long run) by doing the following: Now write down the Start value on a

piece of paper - this is important because the loop data will be lost when you truncate.

Touch Edit and move the Start point to the very beginning. Truncate, touch Loop

FWD and set the Start point to the number closest to what you wrote down before.

Zoom in as far as possible and adjust the Start point to be exactly what you wrote down.
