Audiosnap is one element of Sonar that I have yet to delve into much. I read in the manual there are different methods to get similar results, so I'm not sure what is the best route to take for my particular issue.
 
I'm trying to get my bass guitar lines to play really tight to the drums. Like most players, I'm not a machine, and noticed some areas that could be a little tighter. What would be the best use of audio snap to do this? I'm using EZDrummer 2, so it would be syncing an audio track (bass guitar) to a midi track (drums).
 
Thanks guys.

turn on audiosnap and start moving transient markers :-)
seriously, it can be tedious. Melodyne can also help you accomplish with some times better results.
however I still use audiosnap.
sometimes I don't even need to use audio snap, I simply go in and make tight slices/zoomed in real close and nudge the clip to line right up.
 
in your case you might be better off using the inline piano roll view with the bass track on the next track down.
use the TAB key to move one note ahead at a time (tedious) and make corrections as needed.
 
im about to add my opinion in here. if it were me, which it is not, I wouldn't go completely berserk/ADD with it.
you will lose that natural sound we all look for in music, that thing we are losing as we become more advanced in digital audio.

Assuming the drums are synced/quantized to the timeline, you can just enable Audiosnap on the bass track, check that the tempo and transient detection is accurate, and quantize the bass to the timeline. Then set the offline algorithm in the AS Palette to Radius Solo (Bass) and Freeze or Bounce to Track to render the stretching with the offline algorithm.
 
Dialing in the transient markers is the tricky part. In my experience, bass lines will tend to have a lot of superfluous transient markers that need to be disabled because the low frequencies confuse the detection algorithm. Also, the current algorithm tends to place markers late which my not give the best results.
 
Depending on how busy the part is, you may be better off just manually adjusting the worst of the timing errors by dragging individual transients as Chuck suggested.

I recently had an AudioSnap breakthrough when adjusting guitar parts (not that different from bass...), where I realized how crucial it is to disable transient markers that don't fall on a transient.
 
I'll give an example with bass. Suppose you have two bass notes and the attack of the first one has to hit earlier. There's a transient marker at the attack of each note - this is good. However, there's another transient marker about 1/4 way into the first note. You need to disable this, or when you move the first transient marker earlier, it will stretch only the first 1/4 of the note. You want it to stretch the entire note.

I think Audio Snap is a great tool for quick timing corrections on specific transients. As mentioned above, it can be tedious to align clips with lots of transients. Sometimes it's just easier (and quicker) to record the part again.....
