A grid is the set of divisions on a DAW timeline or piano roll that marks bars, beats, and note values. It provides a reference when moving audio clips and MIDI notes and helps align edits with the rhythm of the song.
Grid resolution
The spacing can usually be changed to bars, quarter notes, eighth notes, sixteenth notes, and other values. Use a triplet grid for triplet rhythms. Some DAWs also provide an adaptive grid that changes its spacing with the current zoom level.
How snapping relates to the grid
With snapping enabled, moving, splitting, or selecting an item pulls the edit toward the nearest grid line. This is useful for precise beat-based placement. Temporarily disable snapping or choose a finer resolution when you need to preserve smaller timing differences.
Using the grid for MIDI
In a piano roll, the grid provides a reference for note start positions and lengths. Moving a recorded performance closer to the grid is called quantization. Applying it too strongly can remove the natural timing of the performance, so adjust the amount when possible.
Using the grid for audio
The grid helps you set loop lengths in bars and duplicate clips according to the song structure. A waveform transient does not always fall exactly on a grid line, however. Use what you hear as the final guide when aligning the musical attack.
Knowing when to leave the grid
Groove, playing ahead of or behind the beat, and ornamental notes may intentionally sit away from the divisions. The goal is not to make every item look perfectly aligned, but to support a clear pulse while preserving the expression of the performance.
