Save (groove pattern) - Saves the current Groove Pattern to file.

A Groove Pattern is a set of (user defined) locations on the beat-grid where Slices (if present) will be snapped to that position and their Slice Markers will move in responde to the Groove knob.

NOTE: To add a Downbeat or Warp marker where no marker currently exists, first add a Warp marker, then change its type. Warp markers are similar to Region markers in Edison and Slicex, with the difference they will time-stretch the sample data either side of them when dragged.

Warp markers - To set: Hold ( Shift) and click to Add Warp markers OR double click on the location to add/remove the marker.

In this case the downbeat marker will automatically align with the start of the nearest Bar when the sample is dragged or sent to FL Studio. If you save the sample to a file, then Markers are preserved. NOTE: Markers are normally stripped from the sample when using the Drag selection and Send to playlist icons. Any downbeat markers will be used to determine the start of a bar and then warp markers will be automatically placed at beat boundaries that are detected in the sample.

Downbeat marker - To set: Right-click an existing warp-marker.
