Unify2 crashing in Cakewalk Sonar

What version of Windows are you using? If Windows 11, was it updated recently?

I've been using Unify 2 in Sonar extensively since Unify 2 was released, and it works great. I frequently use 5 - 10 instances of Unify 2 in a Sonar project. 

In fact, I almost never create a track without it. I have the paid version of Cakewalk Sonar, and keep it updated to the current version.

Thanks for responding.  It's good to know Unify2 is working reliably for you in Sonar.  I should have mentioned I'm running updated Win11 and updated paid Sonar.  I think I found the hang problem which seemed to be an automation lane I was using to switch Baby Audio Transit bypass parameter on and off.  I found a workaround.  But the problem with Sonar crashing when simply saving a Unify2 track template still occurs.

The current version of Windows 11 updated its MIDI driver, and that has caused lots of problems with audio software. I don't know if that is the cause of your problem, but it is worth checking.

Looks like I'll need to install Sonar - if others can repeat a crash on saving a track template specifically it would be good to know.

@mschiff I also haven't forgotten about the issue you were seeing with Unisynth - will try to get you another test build focusing on sample loading logging (still no reports of issues on that from others).

Sorry, I keep changing this message.  I just now opened 2 different projects with around 6 or so Unify2 Instances.  I get consistent crashes with those projects when trying to save the track template.  But with a basic project with just one instance seems to work ok.  So I don't know what's going on with this.  Something seems to be on the edge.  I attached the Cakewalk dumps (.dmp) and associated .txt file if that helps.  Keeps mentioning Access Violations.  

There's a whole thread on Cakewalk Forum about "Crash after Error Code c0000005" from 2023.

I'm looking into it - thanks for sharing the crash dump.

I do have a fix that could be related to the cause of the crash - it will get integrated into the next official release, however I also notice from your crash dump files the buffer size is reported as 5 samples - are those your Sonar audio device buffer settings?  (Typically we'd recommend running at  between 128 to 256 samples buffer size.)

(I've tested loading Unify2 and saving template projects in Sonar/Windows 11 with my latest build - and it's not crashing.)

My buffer size is 256.  Meanwhile, I'm real sure I found out what's causing the crashes.  I forgot that in today's testing I still had transit2 in the effects bin of the track that was crashing while saving track template.  I removed it and it doesn't crash now.  There seems to be a problem with transit2 and Sonar.  I'll find an alternative to transit2 - it was just doing autopanning.  If you have transit2, maybe you could try inserting it in the track effects bin.  Thanks for your support.
