familiar with the Scrub function, you may want to try a
longer length, such as 70 or 80ms.

General Guidelines for Using Scrub
Before using Scrub, you should do two things:
• Set the TIME/VALUE dial to adjust frame increments.
• Set the Scrub Direction using Preview To and Preview
From.
Set the TIME/VALUE Dial to Adjust Frame
Increments
1. Cursor up [
] to access the top section of the VS-1680
display screen.
2. Press [
] to move the cursor to the last pair of
numbers just after the small "f" in the time display.
These are Sub Frames.
fig.02-06a
Hour Minute Second Frame
There are 100 Sub Frames in each frame. With the cursor at
this position, each click of the TIME/VALUE dial advances
the play position by 11 hundredths (11/100th) of a frame.
Hold [SHIFT] and slowly turn the TIME/VALUE dial. Now
each click moves the edit line by exactly one hundredth of a
frame. One hundredth (1/100th) of a frame is equivalent to
one three thousandths (1/3,000th) of a second.
For scrubbing, start with the cursor under the Frame value.
Then later, as you need a finer editing resolution, press
[ ] to move the cursor over to Sub Frames. As you try
scrubbing, turn the TIME/VALUE slowly and smoothly for
the best results.
Setting Scrub Direction
When using the Scrub function in the VS-1680, it is possible
to scrub both forward and backward. That is, you can turn

Cursor
the TIME/VALUE dial either clockwise or counter-clockwise
to find an edit point. If you are trying to find the beginning of
a note or a kick drum, you will most likely start by turning
the TIME/VALUE dial clockwise.
If you are editing dialog and need to find the end of a spoken
word, you would likely locate just past the word and scrub
backwards by turning the TIME/VALUE dial counter-
clockwise until you begin to hear the sound that signifies the
end of the word. When editing dialog, radio or TV spots, you
will probably use the counter-clockwise method of scrubbing
more frequently than when editing music tracks.
Whenever you use Scrub, program the scrub direction for
either clockwise scrubbing or counter-clockwise scrubbing.
Clockwise Scrubbing:
Press [PREVIEW TO] once before pressing [SCRUB]
Counter-clockwise Scrubbing:
Press [PREVIEW FROM] once before pressing [SCRUB]
