The other day I loaded a 13 mic drum recording in Melodyne Studio, first let it make a "constant tempo" and then selected all and quantized to 90 percent (because I was lazy and wanted to see how much I'd need to fix). To my (rather great) surprise, it worked perfectly. No artifacts and even stuff like small rolls that I thought would get messed up were fine (I didn't specificy "16ths" or anything but used "auto"). All I had to do was export and reload into Sonar.
 
I could probably do this within Sonar but I haven't really dug into how the Sonar/Melodyne tempo thing works, nor tried to transfer 13 4 minute tracks to Melodyne with ARA.

As a drummer, I struggled with using Audio Snap for years.  I just found it unreliable, anti-intuitive and unpredictable.  Now that I have Melodyne Studio, I don't even touch Audio Snap.  While Audio Snap could be a great tool, it's never been implemented properly IMHO.  This is one of the few areas in an otherwise excellent DAW that needs to be ripped out and started again.

Yes, I have pointed out a few areas that could be improved in Audio Snap. But it is close, it is almost there and I am not giving up. 
 
Also, it depends on what you are trying to do. If you are trying to fix vocal timing I would not use Audio Snap at all. I would use Melodyne or Vocalign. For keeping absolute phase relationships when fixing timing on acoustic multi-track drums, I would use Audio Snap to help automate some of the tasks.
 
If Audio Snap gets a little love and becomes accurate on transient detection, and allows different groups to be created after slicing, I would use Audio Snap for all drum timing correction all the time.

I found this video, he is running into many of the same problems here and made a feature request, though he says in the comments that he never actually submitted it to the bakers here...

Thanks ChuckC, I am the guy who made that video you referenced...ha ha. I do have some updated info on this whole thing along with some new workflows in SONAR that have sped up this most tedious of tasks.
 
I will make a new video on that shortly, very soon.
 
For a quick overview I can say that all the cutting and crossfading can indeed be done with automated processes within SONAR. However, the lack of accuracy is still the big thorn-in-the-side for Audio Snap. Audio Snap still does not correctly detect the start of transients like it should. If that one thing were fixed, this would be a near perfect tool.
 
In my updated video, I will demonstrate a few different workflows for slicing and dicing multi-track drum tracks for quantizing with and without the use of Audio Snap. All of these include the automation of filling the gaps and crossfading after quantizing is finished.
 
The new video will be more concise and to the point.
 
Thank you for referencing that...

Have you seen this? https://accusonus.com/products/regroover

It slices/dices multitrack drums into discrete pieces. I picked up a free copy of the lite essentials version as a giveaway from Focusrite, but haven't tried it yet. Looks interesting.

Thank you for sharing. I can certainly see how many people could find this very useful, however I think it is aimed at a different purpose. The drum editing that I do doesn't require me to isolate different "layers" of drum loops. I have recorded my own multi-track drums, discretely recorded to their own tracks already. What I am trying to do is tighten up the timing of a real human drummer on a real acoustic kit.
 
If Audio Snap had a more accurate transient detection mode and SONAR was able to create new groups when Audio Snap splits clips, that would be the perfect solution for what I and others are trying to do. As of now, the methods I outlined in the three videos I made show a good combo of manual workflow intertwined with Audio Snap to get this job done.
 
This product you have shared is a great solution for those working with drum loops and if I ever do anything like that I will reach for this. Thank you.
