Beat Grid

A Beat Grid is a series of markers superimposed on the track waveform that indicates the beats
or transients in the music structure.
A Beat Grid allows ITCH to know precisely where each beat occurs, and locates the exact start
of each bar. This accurate beat information opens up possibilities for users to further manipulate
a track, and for precise track syncing and advanced looping features.
Analysing an audio file calculates the average BPM of a given track. Some tracks' BPMs are
linear, so setting an accurate beat grid is easy, only requiring you to set the first downbeat Beat
Marker. If you have tracks with variable BPMs you can also set custom Beat Markers, which will
snap the grid more accurately to the track.
Enable Beat Grid
To activate the Beat Grid, ensure that the Enable Beat Grid checkbox on the Setup screen is
ticked (SETUP > PLAYBACK > GENERAL).
Beat Grid Waveform View
The Beat Grid is placed on top of the waveform overview. It is displayed as follows:
• A full white vertical line is a Beat Marker indicating the beginning of each Beat Grid Bar.
• Each Beat Marker has the bar number at the top.
• The first Beat Marker is called the Downbeat Marker and is a thick red line on the first
beat.
• The Downbeat Marker is always bar number 1.
• Each Beat Grid Bar is divided up into 4 equal sub-bars, indicated by short white lines.
• A thick red line also indicates a manually set Beat Marker.
Before creating a Beat Grid
Setting up a Beat Grid relies on the track having been analysed, so that an accurate BPM value
is known. ITCH can then accurately set the Beat Grid markers on the track's beats or transients.
