I'll send an error report out on this one as I can re-produce it every time, but can some others give it a go and see if they get it?

 - Any midi track. Even just a single MIDI track not routed to any sounds.
 - Record some midi onto it
 - Insert the midi transpose plug onto that clip
 - Now delete the clip
 - Sonar crashes - pretty clean crash. It tries to autosave but doesn't succeed. Starts up again fine (no damn sonar.exe hanging in the Task Manager)

I noticed it on a song I was working on, then tried it out on just a brand now project with the default template - one midi and one audio track. Simply followed above and it crashed also.

X1d.

Simple workaround by the way. Just delete the transpose plug first, then delete the midi clip. Works fine.

Let me know if you see this too! Thanks!

Didn't crash my system. Not a bug. 

I just tried this. Expanded, X1d.

Sonar crashed.

It crashed my computer, also. I sent a bug report to CW.

Thanks for taking the time to confirm this one guys!

Dave, what are you doing?!?! Can't even make your SONAR crash?!?! Haha. Did you place the transpose on the clip, or the track? It has to be on the clip. It's all clip stuff here, not track stuff.

also happens with midi clips using the echo/delay midi effect...

cheers guys

Hmm, wonder if maybe it happens with ALL midi plugs! Must check this out...

It's a bug here. 

Sometime ago, I processed a midi track with Cakewalk Midi FX effect. Instead of applying the effect, I accidentally inserted the effect. Crashed X1 when I delete the midi track, and the first time I use the auto bug reporter.


Edit: I was using Velocity Fx.

Yes this is a known bug. Delete ANY midi clip with ANY of cakewalks Midi Effects inserted will Always result in a Fatal exception.... Still waiting on a fix. Delete the effect first. Also dragging a midi fx from clip to bin or clip to clip will crash as well.
