I've sent so many crash reports to Cakewalk without getting a single response. Maddening.

I've contacted Melodyne directly and they express a sad resignation that the problem is Cakewalk's and that unless Cakewalk steps in and fixes the integration problem, it's not going to get fixed.

Melodyne is aware of the problem. Their hands appear to be tied.

Here's what we know;
1.Creating a Region FX of Melodyne on even the smallest of clips will crash the project more often than not.
2.When it doesn't crash, the blob monitoring does not work at all.

What is the point of sending these crash reports to Cakewalk if there is not a response? Even if they have no clue about how to fix it yet; at least acknowledge that they SEE the problem and that, yes, it needs to be fixed.

Over the last few years, I feel Cakewalk has taken a defensive stance on support and has made users feel like the problems experienced are annoying, when reported, and not the fault of Cakewalk.

How about a workaround? Anyone have suggestions?

And here's an interesting observation a user stumbled upon.
The GUI of the mix board seems to have an impact on whether a Melodyne crashes or not!

Interesting because I am still on v2 of Melodyne and I have not ever had a crash.  I render each clip when I am done with it though.
 
Just because Melodyne says it Cake's issue, doesn't really mean it is.

I just started having this problem due to melodyne syncing being the worst it's been since the latest splat update. First time I've tried freezing melodyne tracks.. Crashes on save.

I know... Bounce to clips blah blah.. I want to be able to re tweak the tuning later if required.. Not too much to ask that this works properly is it?

Just add it to the list of unfixed know issues. Maybe now the mac platform has been dumped resources can be put to fixing known issues.

Can you provide a recipe to reproduce? I'm not sure if you're saying that freezing a Melodyne track causes a problem, or whether you're saying that if Melodyne tracks are frozen, then when you later save the project, it crashes.
 
I ask because I don't have any problems with Melodyne so I'm curious what the workflow differences are. If there is a problem and it can be isolated/repeatable, it can probably be fixed.

Craig, post #3 has the recipe . . . it's after freezing the Melodyne track, then subsequently saving the project that causes the crash . . . give it a whirl. I'm surprised it's been 7 months since I posted this, and no action from either Cakewalk or Celemony ? Perhaps it's not so important to anyone else's workflow ?

OK, I tried something different with Melodyne, Keep in mind I only have Melodyne Essentials 4.1.1.011 at the moment, but I am planning on upgrading to Melodyne Editor before July ends so I can take advantage of the great Melodyne upgrade sale at Everyplugin.com
 
When I used Melodyne as everyone else, Sonar Crashed.
 
Create new project,
Added an audio track of Vocals,.
Select Region FX > Melodyne> Created Region Fx
Selected the freeze button.
Attempted to Save
Sonar Platinum Crashed.
 
===========
 
I then tried using Melodyne a different way..
 
Create new project,
Added an audio track of Vocals.
Highlighted the vocals track
Inserted Melodyne from the FX bin as a plugin
Clicked the Transfer button in Melodyne  and began playing of the Vocals track
The vocals began rendering in Melodyne, this is done in real time so you may want to use a clip only.
Once vocals rendered in Melodyne, I froze the vocal track and then clicked save
Nothing happened, the Project was saved.
 
I was able to re-open the project and unfreeze the vocal track
 
It is by no means the fastest way, but you don't have to worry about crashing Sonar 

So you're using Melodyne as an FX plugin instead of a Region FX as a workaround to the crashfest. Thanks for taking the time to test this out Jesse G . . . though, not clear, are the ARA Cakewalk + Celemony optimal functions still available when using as a plugin ? I'm not seeing the advantage of using it this way, but will surely give it a try.

My posts are disappearing again!   I tried submitting it three times, after editing the original post, now it's gone.
If they should suddenly reappear, sorry for the duplicate posts.   These seems to be happening quite a lot lately for me.
(It was a post about Melodyne crashing for me under the same circumstances as the OP)

"I ask because I don't have any problems with Melodyne"

I find this very surprising. No problems with melodyne? It's always been flakey for me, but fairly usable until now.

Freeze a melodyne track and save =crash
