This page allows you to cut, trim or normalize a sample, as well
as edit the loop points. The sample can be played over the full
keyboard.
SM (Sample)
Selected sample.
Waveform display
This is the graphical display of the selected sample waveform,
i.e., the one you can hear when playing the keyboard. The area
included between the Start and End points is highlighted (dark
background).
Parameters
Start (Sample Start)
This is the sample start point (in samples). You may edit this
point, as well as the End point, to shorten the sample. Changing
the Sample Start cuts out the attack portion of the sound.
Note: When moving the "Start" point forward, and reach the
"Loop Start" point, this latter is also moved forward.
Warning: When saving the edited sample (Write Sample opera-
tion), the segments exceeding the Start and End points are perma-
nently removed.
Loop Start
Note: This parameter has no effect, unless you don't turn the loop
on. Use the "Loop On" parameter on the "Sample Edit > Loop
Edit" page to turn the loop on (see page 239).
Use this parameter to adjust the Loop Start point. When you
adjust this parameter, an audible click may appear, due to a pitch
and/or level mismatch between the starting and ending points of
the loop. Move the Loop Start and Loop/Sample End point, so
that the click can no longer be heard.
When editing audio grooves, the Loop Start should match the
Sample Start point. This parameter usually differs from the Sam-
ple Start in ordinary sounds (i.e., a guitar, a piano, a voice...).
Loop Start (L)
Length
Sample Start (S)
End (Sample/Loop End)
This is the sample and loop end point (in samples). You may edit
this point, to shorten the sample.
Warning: When saving the edited sample (Write Sample opera-
tion), the segments exceeding the Start and End points are perma-
nently removed.
Use Zero
If this parameter is turned on, when you move the Start, Loop
Start and End points, the selection fall on the nearest zero-cross-
ing point (i.e., points where the waveform crosses the x-axis, and
goes from negative to positive, or from positive to negative val-
ues). This will make loops more accurate, and will reduce the
risk of "clicks".
OrigNote (Original Note)
Original pitch of the sampled note. While this parameter has no
effect on sound, it will be useful to identify the original pitch of
the sample and when assigning a sample to the multisample.
For example, if you sample a C4, set this parameter to "C4".
When the sample will be assigned to a keyboard zone of the mul-
tisample, it will be transposed (if needed) according to this
parameter, to avoid a change of the original pitch.
Zoom
Use these buttons to change the size of the waveform shown in
the diagram. When a button is greyed-out, it means the maxi-
mum or minimum value has been reached.
