/ EDIT SAMPLE

XFADE LENGTH This sets the length of the loop crossfade. What this function does is to

crossfade a portion of the sound before and after the loop according to

the time set in the XFADE LENGTH field. This will (should!) smooth out

any glitches you may have. There are no rules and so some

experimentation will be required. Having said that, although the process

is not guaranteed, this can be very effective in getting smooth loops.

The XFADE LENGTH also has a WINDOW function. Pressing WINDOW

reveals these further functions:

FADE PROFILE Here you may select from a choice of crossfade curves (LINEAR, LOG

and SINE). Of these, for a smooth crossfade, SINE is possibly the best

selection as it gives what is also known as an ‘equal power’ crossfade

but you may like to experiment for the best results.

XFADE LENGTH This parameter is duplicated for convenience.

CROSSFADE This initiates the crossfade function. Pressing this will display the usual

“Processing sample” progress display followed by the PLAY/KEEP

ORIGINAL/NEW/BOTH and RENAME prompt. You should respond

accordingly to the final prompt according to the results of the XFADE

function.

PLAY LOOP This key will play only the looped portion of the sound you have set. This

is a fast and convenient way to hear the loop without having to also hear

the rest of the sample (particularly useful for long samples!).

However, a feature of this key is that it is a ‘latching’ key - press it once

to play the loop, press it again to stop playing the loop. What this means

is that you can set the loop start and end points in real-time playing

whilst the loop is cycling round.

So, to set a loop, place the LOOP START and END times at position

which ‘look’ good on the waveform display (i.e. at points of equal or

similar amplitude). Now press PLAY LOOP to play the loop you have

set. If it ‘glitches’ with pops and clicks, you can now adjust the start and

end points until the glitches are reduced (you could also use AUTO FIND

- see below) to assist you). Once you are happy with the loop, press

PLAY LOOP again to stop the loop playing and play as normal from your

keyboard.

NOTE: The PLAY LOOP function is automatically disabled (i.e. loop playback is stopped) as

soon as you leave the LOOP page.
