What happens when you extract a groove that doesn't have a transient on every 16th note?

I frequently use 'Extract Groove' to copy a live musician's rhythmic feel, but I have a question about how this works if there isn't a transient on every 16th note.  Often a drum break (for example) will have hits only on a small number of 16th notes with a bar.

This doesn't seem to hurt anything, judging by ear, but what happens when you groove quantize a clip and a particular note/transient isn't close to any particular note in the groove template?

And should I be editing my groove templates by adding hits near the 16th notes where there was no transient in the original audio or midi clip?

    If the base grid of the groove is 16th (which is the default), and some 16th doesn't have a near transient in the clip you want to extract a groove from, the groove acts as if there were a 16th on the grid line. You can drag a groove from the groove pool to a MIDI track: if you see no note on one of the 16th, it means that 16th is "straight" when the groove is applied. No need to add a note or transient.

    Groove in Live is real time and relative, it moves notes towards the groove grid. 

    The way it works is, if a note in a clip is quantized, and a groove is applied to that clip with a Timing of 100%, the note will be moved on the corresponding groove grid line. If a note is not quantized in the original clip, the note will be moved proportionally towards the corresponding groove grid line. This is a reason for the "Quantize" parameter in the Groove Pool: it allows to pre-quantize the clip and therefore make sure all notes are moved to the groove grid lines.

    That aspect of groove allows to have "rolls", made of many notes in between 2 grid lines, and still have these notes play after applying a groove. The roll gets the "feel" of the groove, but are not removed (which a groove/quantize feature would do).

    Hope that helps.
