How can we help?


Beatgrids are a series of markers that are placed on beats in a song to help determine the BPM. When a file is loaded into Serato Sample, a Beatgrid is created during the analysis process. An incorrect Beatgrid can cause sync or tempo matching issues.

Grid Edit mode

While hovering over the main waveform, click the GRID button to enable Grid Edit Mode. This will reveal the Beatgrid controls and display the Beatgrid on the currently loaded song.

You can click and drag the markers with your mouse to adjust their position. Hold control while clicking and dragging on any portion of the Beatgrid to slip the entire Beatgrid.


There are three kinds of Beagrid markers:

  1. Tempo markers
    Tempo markers are red markers that can be placed using the ‘Set’ button in the Beatgrid controls. Click and drag on a tempo marker to move it around the beatgrid.
    When a single Tempo marker is used, clicking and dragging on the portion of the Beatgrid before, or on the Tempo marker moves the entire Beatgrid, while clicking and dragging on any marker after the respective Tempo marker contracts and stretches the entire Beatgrid, adjusting the BPM in real-time.
    Using 2 or more Tempo markers allows you to contract and stretch just a portion of the Beatgrid, by clicking and dragging on a Beat or Bar marker, after the next Tempo marker. Clicking and dragging on the preceding Tempo marker or the portion of the Beatgrid prior to this, allows you to contract and stretch the portion before the second Tempo marker.
  2. Bar markers
    Bar markers can be identified by full height grey lines with a small number next to them indicating the bar count. Click and drag a Bar Marker to adjust the Beatgrid and any adjacent Beat or Bar markers.
  3. Beat marker
    These are the short grey markers between Bar markers, and indicate the 3 remaining beats or counts that, along with the bar marker, make up a 4 beat bar.
    Click and drag on these markers to adjust the Beatgrid and any grey adjacent Beat or Bar markers.

There are also several dedicated Grid Edit controls:

  • SAVE:
    Click on this button after editing, adding or clearing beatgrid markers to save the beatgrid.
    NOTE: The ‘Save’ button will not appear until changes have been made to the beatgrid in Grid Edit mode.
    Revert or undo the changes made after entering Grid Edit mode.
  • BPM:
    Adjust the BPM value and subsequent beatgrid by clicking and dragging up or down on the BPM value, the arrows beside the value, or by using the x2 and ½ buttons.
    Hold SHIFT or CTRL while clicking and dragging up or down to make coarse or fine adjustments.
    Alternatively, double-click on the BPM and use your keyboard to enter a known value.
    while Serato Sample is a ‘playing’ state, mouse-over ‘BPM’ to reveal TAP, which allows you to ‘Tap’ the tempo to estimate the BPM. The BPM value will turn yellow to indicate ‘Taps’ are being registered.
    Turn on the metronome to hear the BPM while in Grid Edit mode, while Serato Sample is ‘playing’ the source file. The metronome is not audible when auditioning or triggering a Pad.
    Place a new Tempo marker, at the current position of the playhead, and populate subsequent beatgrid markers based on the current BPM value.
    NOTE: This clears all current markers.
    Click on the left or right Adjust arrows to contract or stretch the beatgrid.
    With only a single Tempo marker set, and the playhead position on or after the marker, using the ADJUST controls will contract and stretch the entire beatgrid, adjusting the BPM in real-time.
    With two or more Tempo markers set using the ADJUST controls allow you to contract or stretch specific portions of the beatgrid, depending on the relative position of each Tempo marker. Setting subsequent, additional Tempo markers and moving the current Playhead position between those markers will allow you to contract or stretch beatgrid regions in isolation.
  • SET:
    Place a new Tempo Marker, at the position of the playhead marker. You can have a maximum of 128 Tempo Markers.
  • CLEAR:
    Remove the Tempo Marker closest to the playhead, or remove all markers if there are no remaining Tempo Markers.
    Remove all markers and clear the current beatgrid.
