Chapter 23 Frequently Asked Questions
1. Hold the Track 1 STATUS button. If the EFFECT 1/3 
RTN or EFFECT 2/4 RTN buttons begin to flash, press 
them so they stop flashing.
2. Repeat this procedure for Tracks 2-18.
Another common reason for being unable to hear an effects 
processor is that effect return for that effect is set to “0.” Use 
the following procedure to check the effect return level:
1. Press the [EDIT/SOLO] button to display the Master 
screen. 
2. Use [
], [
], [
], and [
] and the TIME/
VALUE dial to select the desired return level for FX 1-4 
(100 is the default value).
How Do I Use the Scrub and 
Waveform Display Features?
The Scrub and Waveform Display functions of the VS-1824 
are extremely useful when performing track edits such as 
Cut, Copy, and Erase. The Waveform Display helps you find 
exact edit points in your audio by providing a graphic 
representation of a particular audio waveform. The Scrub 
function allows you to hear that edit point by playing back a 
loop (with a resolution as fine as 25ms) of your audio. You 
can control the audio that is being looped by selecting the 
track you want to hear and using the dial to move the audio 
back and forth across the “Now Line” (the solid line that 
runs across the middle of the Waveform display). To use the 
Scrub and Waveform Display functions effectively, it is 
important that you understand the control parameters used 
in each function.
Setting the Scrub Length
There are two factors that can affect the precision with which 
you can scrub audio in the VS-1824: the Scrub Length and the 
position of the cursor in the time display. Scrub Length 
controls the size (in milliseconds) of the section of audio that 
is looped, and can set as low as 25ms or as high as 100ms. 
The default value is 45ms. Use the following procedure to 
adjust the Scrub Length:
1. Press [STOP] if the VS-1824 is currently playing.
2. Hold [SHIFT] and press [SCRUB], and the “Scrub 
Length” screen will appear in the display.
3. Use the TIME/VALUE dial to adjust the scrub length as 
desired.
4. Press [PLAY (DISPLAY)] to return to the Playlist display.
The position of the cursor in the time display will control the 
amount of time advanced with each turn of the TIME/
VALUE dial. You can set the dial to advance in hour, minute, 
second, frame, or even subframe increments. You can also set 
it to advance by measures, beats, or markers. Setting the 
cursor under the frame portion of the time display will work 
best for most editing applications. Use the following 
procedure to adjust the position of the cursor in the time 
display:
1. Press [PLAY (DISPLAY)] so that the main Play screen 
appears in the display.
2. Hold [SHIFT] and press [
] until the time portion of 
the display is selected.
3. Use [
] and [
] to place the cursor under the 
desired increment for advancing the time display. For 
example, if you want the VS-1824 to move one frame at a 
time when the TIME/VALUE dial is turned, the time 
display would be as follows: 00h00m00s00f00.
To advance the time display in subframe increments, set the 
cursor under the frame portion of the time display and turn 
the TIME/VALUE dial. The counter will move in increments 
of 10 subframes. To advance the time display in single 
subframe increments, hold [SHIFT] while you turn the 
TIME/VALUE dial.
What do the X and Y Parameters do?
The VS-1824 allows you to zoom in and out on both the 
amplitude (level) and time values of the Waveform display. 
The default zoom values for amplitude and time are 1 and 
16, respectively. Use the following procedure to adjust the 
zoom controls on the Waveform display:
1. Press [PLAY (DISPLAY)] so that the main Play screen 
appears.
2. Use [
] and [
] to select the track to be viewed in 
the Waveform display and advance the song to a point 
where there is audio present on that track.
3. Press [F5 (WAVE)] to view the Waveform display.
4. Use [F1 (ZOOM+)] and [F2 (ZOOM-)] to zoom in and out 
on the amplitude (level) portion of the display (vertical).
5. Use [F3 (
←→
)] and [F4 (
→←
)] to zoom in and out on the 
time portion of the display (horizontal).
6. Press [F5 (WAVE)] when you are finished to close the 
Waveform display.
