Trim/Loop; Waveform; [F1] Trim/Loop - Yamaha A4000 Owner's Manual

EDIT-TRIM/LOOP

1. TRIM/LOOP

This section describes the EDIT mode's TRIM/LOOP func-
tion. You use this function to change the playback area on the
waveform (the playback "start" and "end" points), to trim off
extraneous waveform data, to set the playback direction (for-
ward or backward) and loop characteristics (loop range and
type), and to make various other related settings.
• Keep in mind that the [COMMAND/EXIT] button gives you rapid
access to a number of helpful commands while you are working
with this function. For example, you can use the [COMMAND/EXIT]
button when you want to save your edit results to disk, or when you
want to cancel your new changes and restore the previously saved
data.
Press the [EDIT] button and then the [F1] button to go to the
TRIM/LOOP function.
3 display pages are provided: Waveform, SmpInfo (Sample
Information — page 124), and LoopRmx (Loop Remix —
page 125).
• See the "Basic Operation" section on page 78 for details on switch-
ing between display pages.

[ Turn] Wave Start Address
Sets the playback "start" address on the waveform. (Note
that the waveform itself always starts at address 0.) The
concept is illustrated below.
[Range] 0 — Wave End Address
Start Address
Playback Area of Waveform
• When "–
Mode, The Wave Start Address cannot be set later
than the Loop Start Address.
[ Press] ZOOM IN
Press this knob to expand the waveform display. This can
be repeated until maximum magnification is reached.
Knob 3
[ Turn] Wave End Address
Sets the playback "end" address on the waveform.
The actual playback endpoint also depends on the loop-
mode setting that you make at the Wave Mode page.
[Range] Wave Start Address — End of wave data.
The range of this parameter changes according
to the setting of the End Type parameter (page
124).
• End Type = Address ... Sets the wave end
address (this is the normal function).
• End Type = Length ... Specifies the actual play-
back length (Wave End Address - Wave Start
Address).
• End Type = Time ... Specifies the actual playback
time in seconds (From the Wave Start Address
to the Wave End Address at the original pitch
of the sample).
• End Type = Beat ... Specifies the playback time
(Wave Start Address to Wave End Address at
the original pitch of the sample) in beats
based on the Loop Tempo setting.
• When "–
Mode, The Wave End Address cannot be set earlier
than the Loop End Address.
[ Press] ZOOM OUT
Reduces the waveform display. This can be repeated until
the minimum magnification level is reached.
