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.
