In any case, the beveled edges aren't consistent (at least on my system), so I need to put together a bug report.

 
If you inserted a clip, selected it and then from the context menu selected Groove-Clip Looping (or simply pressed Ctrl+L) and couldn’t see any bevelled edges, my guess is that you imported a sample with groove clip capabilities already enabled. If that indeed was the case, you would effectively have toggled the groove clip capabilities off, resulting I sharp cornered clips.
 
On a moderate sized monitor with high resolution, the bevelled edges might be a bit hard to see, especially if the clip and track colours doesn’t give good enough contrast. In this particular case I think that Mercury works much better than Tungsten.

What I am seeing is that I drag and drop a piece of audio (In FLAC form), split it in a few places, and the resulting clips have beveled corners. Then I toggle GCL, and the beveled corners go away, with the GCL functioning as expected.
 
If I fiddle with it enough times, I can get it to where the toggle is correct, that is, when the clip is GCL'd, the corners are beveled, but at least initially, it's backwards. This can't be expected behavior.

if you convert the clip to WAV before importing, does it behave correctly? it could be getting lost in the internal conversion

Okay, I just tried it again. What I am seeing is that I drag and drop a FLAC file, then split it at various points.
 
Each resulting clip has the lower corners beveled, but not the top.
 
When I enabled GCL on one clip, I got the beveled corners on all 4, and it behaved as expected. When I turned GCL off on the clip, all of the bevels went away.
 
I guess my question at this point is what's up with the bevels at the lower corners?
 
The FLAC file under test is just a rip from a CD that I'm using as a piece of audio to play with. What I'm doing is messing about trying to build my Cakechops on something that's not in the critical path, so I grabbed whatever I could find on my 'puter. There should be no embedded information, it's not Acidized or anything, just raw audio for me to play with the editing functions.
 
I'm really hurting for a PDF manual I can curl up with. I loves me some CbB, and I'm a BandLab rah-rah, but gimme a PDF manual with good searchability, pleeeease.

Anyone with a recent version of SONAR installed has a 2,348 page PDF available in the program folder called SONAR Reference Guide. Not sure why it hasn’t been distributed with CbB, but as that PDF hasn’t been updated since early 2017 it’s probably considered obsolete and too much work to keep updated alongside the online documentation. Maybe you can ask BandLab support for a copy? I don’t want to break the EULA.
 

A 2,348 page PDF sounds like a treat to me. I shall ask them. Only a year out of date doesn't sound too bad. Thanks for the tip!
