Placing samples on DVS

Let's take a look at how to place samples on DVS.

Let's start with a brief explanation. The aim here is to place samples in an audio file so as to have a sample for each turn of the vinyl, for example. Sound familiar? Scratch vinyl tools, of course. They're edited in this way so that when the diamond skips a groove, it's always the same sample that's played. We're going to reproduce this type of audio editing.

When it comes to mixing simply with his favorite DVSno problem. With cue points, you can put cues wherever you want, but in limited quantities. So what do you do when you've got an audio file full of samples? And you don't want to cut it up into lots of little pieces?

The principle for placing samples on DVS :

You need to edit the file in a DAW (Digital Audio Workstation). You don't need one in particular - any DAW will do. Then place the samples at equal distances from each other, so that the same amount of time elapses between each sample start..

Getting started

If you put 5 seconds between the beginning of each sample, visually on a CD player or DVS (Digital Vinyl System) mixing software you have a marker in seconds.

So, 0 seconds=1st sample.

Then, 5 seconds=2nd sample, and so on 10,15,20.

I took 5 seconds, the table of 5 is easy to remember.

And on vinyl?

On the other hand, for a file played back on vinyl, the situation becomes more complicated if we want to place a sample at each turn of the record. So we can place them wherever we like, following the principle of a clock: 12H=0°,3H=90°,6H=180°,9H=270°.

To do this, set the DAW to a BPM of 133.33. Now 4 beats equals 1 record revolution. So a sample every four beats is equal to a sample every record revolution. You can see in yellow what represents four beats or one record revolution.

Simply place the beginning of the sample on one of the four beats. 1st beat=12H=0°, 2nd=3H=90°, 3rd=6H=180°, 4th=9H=270°. Of course, this depends on the length of the sample. You can also place several samples on the same turn of the disc if they are short enough. Adjust accordingly.

The result

This is what we get, and now let's compare the waveforms between DVS and DAW.

The part selected in yellow in the DAW represents points 1 to 2 in Serato.

The photo above shows the first track file played back in Serato.

Here is the file for the second track played in Serato and on the right in Ableton. At each quarter-turn a sample is played, then at each half-turn, then at each turn.

The principle also works with the marker on the CD-J 2000 or similar. In the middle of the jog, the red marker makes a revolution every 4 beats. With the pitch at 0%, one revolution equals approximately 1.79 seconds.

I've been looking for this trick or technique for a long time without finding it on the net.

The solution is simple: at 133.33 BPM, the metronome moves at the same speed as a record at 33.3 rpm.

I hope I've helped you.
