DEX 3.20 is Ready for Download | Beats, Bars, and Beat-Grid Editing

DEX 3 Beat-Grid Editor

Download DEX 3.20, now with advanced Beat-Grid Editing!

DEX 3.20 is here and we’re talking beats, bars, beat-grids, beat-grid editing, BPM, and all things rhythm. First, we’ll need to break down the basics of music theory for DJs.

Nearly all modern music is made up of ‘beats’. When a track is 128 BPM it literally means that there are exactly 128 ‘beats per minute’ (beats in a minute). That’s a ‘beat’.

A ‘bar’ is also known as a measure and consists of 4 consecutive beats — at least that is the case with 99% of commercial music available (which is 4-by-4 [4:4]). This equates to 4 beats-per-bar with each beat representing a 1/4 note. Great, so why do you need to know this and what does this mean for DEX 3.20 and the DJs that use it?

New in DEX 3.20: Automatic Down-Beat & Bar Detection

DEX 3.20 is now equipped with automatic down-beat and bar detection. The ‘down beat’ is the first beat in each bar/measure; it marks the starting of a bar. You’ll notice that the ‘down beat’ indicator showcased in the beat-grid (waveform area of the deck) is slightly thicker than the usual beat markers.

The first down-beat (marked automatically DEX 3.20 or by yourself) is numbered ‘1.1’. The first number is the bar number and the second number is the beat number (Bar.Beat). Visually, this specially chosen down-beat is red.

A ‘beat-grid’ consists of all the ‘bars’ and ‘beats’ of a track that you can experience in a visual way as a grid.

DEX 3 has always automatically detected the beat-grid but at times it may not get it right. Breakbeat tracks and downtempo tracks, for example, may be calculated incorrectly at times. In previous DEX 3 versions if the calculation was incorrect, you couldn’t do much about it. That’s no longer the case with DEX 3.20.

Here’s an overview of the freshly added ‘beat-grid editing’. This powerful new feature allows you to properly set the beat-grid and BPM of tracks if DEX 3.20 doesn’t calculate things correctly. Why should you care? A major benefit of a properly calculated beat-grid is much better BPM Sync – looking tracks in step for quality beat mixing.

How is it Done?

Steps to correct the beat-grid of a track:

  1. Select the first down-beat in the track. This will usually be the first energy-intensive beat (IE: the first drum kick). To do so, you need to move/drag the waveform to the play position and hit the set ‘DownBeat’ button
  2. Move/slip the beat-grid left/right until the down-beat marker is aligned perfectly with the beat in the waveform
  3. Adjust the beat size until the next beats align correctly with the beats from the waveform — while you adjust the beat size the BPM value also changes.
  4. Repeat the step above (3) as many times as needed to correct the alignment throughout the whole song (for varying BPM tracks, this is a major plus). Start by scrolling slightly past where the initial down-beat was. Then advanced a bit more (around 20-30 seconds at a time) and re-adjust the beat size. Advanced all the way to the end of the track and correct the beat size as you go
  5. That it. That’s how beat-grid editing works for a track in DEX 3.20 (and up). For songs that have a varying dynamic tempo (such as live-playing bands) or different parts/sections that have a different BPM/beat-grid you can add as many beat-grids throughout the track as you’d like
