Sampling
PRE LISTEN LCD button to hear how the resampled wave will
sound before actually resampling the wave. Press the EX-
ECUTE LCD button to actually resample the selected wave.
• Resampling can cause the loop points (see LOOP POINT, below) to
shift, resulting unwanted noise. If this happens use the LOOP POINT
function to readjust the loop points.
3: LOOP POINT
The controls in this display allow you to trim and loop your
sampled waves as required.
The LOOP/ONE SHOT/REVERSE LCD dials determine
whether the wave will be played as a LOOP (i.e. the wave will
"loop" as long as a key is held), as a ONE SHOT sample (i.e. the
wave will play through once when a key is pressed and then
stop), or as a REVERSE one-shot sample (i.e. the wave plays
through once in reverse).
The AUTO ZERO and LOOP LCD dials are used to trim
sample in the ONE SHOT, REVERSE, and LOOP modes. When
the ONE SHOT or REVERSE mode is selected, the LOOP
SELECT LCD dials select either the START or END address of
the wave. When the LOOP mode is selected the LOOP SELECT
LCD dials select the START, LOOP START or LOOP END
address. The LOOP ADDRESS LCD dials are used to set the
selected address as required. The large ADDRESS
vary the selected address in the largest steps (the highest four
digits) for coarse adjustment, the medium
selected address in medium steps (the 3rd and 4th digits), and
the small vary the selected address in the smallest steps (the
lowest two digits) for fine adjustment. The LEVEL indicators to
the right of each address show the signal level at the current
address — the longer the bar, the higher the signal level. This
makes it easier to locate zero-level points for noise-free trim-
ming and looping. The AUTO ZERO also aid in locating zero-
level points: when the AUTO ZERO parameter is turned ON, the
LOOP ADDRESS LCD dials will automatically only select
points in the wave corresponding to, or adjacent to, zero level
points.
Use the EXTRACT LCD button to automatically remove all
data prior to the specified START point and after the END or
LOOP END point of your sample.
You can play and listen to the wave at any time during the
editing process as long as the wave is selected via the
monitor LCD button. When all LOOP parameters have been set
up as required, press the EXECUTE LCD button to actually edit
the selected wave.
