EDIT SAMPLE
NOTE: It is not possible to loop 'virtual' samples. and so it is only possible to select NO
LOOPING or ONE-SHOT for 'virtual' samples.
The PLAY MODE's WINDOW parameter reveals these further parameters:
The parameters are:
LOOP LOCK
PLAY MODE
LOOP DIRECTION
152
LOOP TIL REL This will play the sample and will loop for as long as
you hold the key but, as soon as you release the
note, the loop will stop playing and the rest of the
sound (if any) will play through the release phase of
the program's envelope.
Once you have set a good loop, you may lock its length and 'slide' it
around the sample to see if it sounds better in a different position.
The PLAY MODE parameter duplicated here for convenience.
You may set FORWARDS or ALTERNATING:
Original with loop start/end settings
Playback with FORWARD loop
Playback with ALTERNATING loop selected
As you can see, you can get a smoother loop with ALTERNATING
selected in some circumstances. ALTERNATING is particularly useful on
long loops with sounds such as strings, etc.. It can also be useful for
looping decaying sounds such as cymbals or pianos.
