Specify the Loop Mode
Use Knob 1 to highlight the third function line on the display ("Auto" & "LpMode"), and use Knob 3
to select the desired Loop Mode. The available loop modes are listed below:
– – No loop
– O Continuous loop; the loop will continue to play until the note(s) is released, then the remain-
der of the loop will play and playback will stop.
O Loop to release: the loop will play until the note(s) is released, then the remaining portion of
the sample will play.
– – No loop; reverse playback.
One No loop one-shot. The sample plays through to the end regardless of note-off.
One No loop; reverse one shot. The sample plays through to the end backwards, regardless of
note-off.
4.
Specify the Loop Start & End Addresses
Use Knob 1 to highlight the second function line on the display ("Loop"), then use Knob 2 and Knob
3 to specify the Loop Start and End addresses, respectively. Dotted vertical lines in the waveform dis-
play show the currently selected Start and End points.
If you need coarser or finer adjustment, use Knob 4 to select the digit in the Start and End values
which will be directly adjusted by Knobs 2 and 3. Your options are x1, x10, x100, x1000, and x10000.
The position of the inverse block cursor in the address values shows the digit currently being adjusted.
You can hear how the edited sample sounds at any point during this process by pressing the [AUDI-
TION] button.
• Note that the Loop values cannot be set "outside" the Wave Start and End points. Obviously, the
Loop Start point cannot be set earlier than the Wave Start Point, and the Loop End Point cannot
be set later than the Wave End Point.
• You can change the units used for trim and loop point specification by scrolling down to the "End-
Type" parameter and using Knob 2 to select the desired unit: "Address", "Length", "Time", or
"Beat". See page 124 for details on this feature.
• The specified Loop Start and End points are saved with the sample data.
Handy Auto-addressing Functions
Sometimes, setting the optimum Wave and Loop points can be a tricky business. Unless your Start and
End points are set precisely to the right points on the sample waveform, you can end up with annoying
clicks and noise. The A5000/A4000 provides a number of auto-addressing functions that can make it
easy to set precise Start and End points.
Use Knob 1 to highlight the third function line ("Auto" and "LpMode"), then use Knob 2 to select the
Auto mode that best suits you purpose (see list below).
off No auto-addressing.
LengLock "Length Lock". When this mode is selected the length of the sample or loop will be precisely
maintained when either the Start or End point is changed. For example, if you adjust the
Loop Start address, the Loop End address will change automatically to maintain a constant
loop length.
Zero When this mode is selected only addresses which correspond to zero-crossing points on the
waveform can be selected. This makes it easy to trim or loop a waveform so that no clicks
are produced at the beginning or end of the sample.
Snap When "Snap" is selected, only addresses corresponding to points on the waveform which
are at exactly the same level as the opposing point can be selected. For example, if you have
set the Start point of a loop, then the End point will always be at precisely the same level as
the Start point. This mode can make it easy to set smooth, noise-free loops.
