I have a track containing a repeating guitar riff. There is a minor timing issue with part of one repetition. I would like to copy another section of the track with better timing and replace the flawed section. In order to avoid clicks at the edges of the pasted clip I would like to crossfade the pasted clip and the original material. Anyone know how to accomplish that with Sonar Platinum?
 
Thanks,
 
Mike

In the Track View, under the Options menu, check Auto Crossfade. You can also choose the crossfade curve from the options menu.

After enabling Auto Crossfades, here's how I would approach it:
 
- Select and copy (Ctrl+C) the good section, preferably with snap enabled at a fairly large value like 1/4, and starting an equal amount of time before and after the wonky part, and with endpoints at points in the waveform where the amplitude is low (snapping to zero-crossings won't matter much since you'll be cross-fading, but you can enable that in Preferences if you like).
- Snap the Now time to that corresponding same beat at the other location by clicking in the Timeline.
- Ctrl+Alt+V to Paste Special, choose 'Replace' and 'Paste As New Clips', and OK.
- Disable snap, zoom in at the Now time, and drag (Slip-Edit) either of the clip edges to overlap the other just a tiny bit (how much depends on what's going on at the overlap - shorter is usually better, maybe only 5-10 milliseconds); the crossfade will be created automatically.
- Without zooming back out, select the pasted clip, hit the keyboard shortcut for Goto Thru (sorry mine's non-default), and drag to create the other crossfade.
