In all my years of using Sonar, I have never used Grooze Quantize.
 
Can someone give me a simple example of what this is for and how you would use it?
 
Thanks.

You've heard of tone-deafness, right? Well, Groove Quantize is for people who are groove-deaf.  If you've never used it, you probably don't need it. 

But, seriously, Groove Quantize is designed to allow you to match the rhythmic feel of a MIDI or audio track to the rhythm pattern in another MIDI or audio track as an alternative to quantizing everything to/toward an evenly-spaced grid. You can quantize to a saved file or to something in your clipboard that you've copied from a MIDI track or from transients in an audio track. But it's the interplay in timing of different tracks/instruments that makes a good groove, so it has limited usefulness as far as I'm concerned. 

I think it's mostly useful if you're starting with a hard-quantized loop that needs some "feel" added to it. If you record everything live in real time, it's probably already got the feel it needs.

It may also come in handy if you have live tracked a take and prefer a particular verse or chorus 'feel' from one of the verse/chorus sections over the others.

Rather than just copy and paste a section extract the groove and apply it to the other sections. That way you have the variations but with the same vibe or j'ne sais quoi.

Interesting.  Thanks guys.

It's used in electronic music to add feel to the midi grid. Say you have a kick that's 4/4 and a snare hitting on 2 and 4, you would use quantize on the high hat to 'push' the notes either behind or ahead of the beat. Classic disco.
