I’m working on a project where many small tempo changes (synced with a live drum track played from tape) and signature changes occur regularly. I’m adding an Omnivocal Track instrument to control a vocoder. Works fine, but…
Song structure regarding tempo and signature:
About 16 to 17 minutes into the track, with a 4/4 signature that changes to 1/2 at 664 and to 3/2 at 673, and a more or less regular a tempo around 168 BPM, there’s a tempo change (Step) to 166 BPM at position 692.3.1.
From there, a gradual tempo change (Ramp) begins to 176.7 BPM at measure 698. Meanwhile, there’s a signature change to 1/4 at measure 696.
Then, there’s a tempo change (Step) at measure 699 to 147.857 BPM… more like a tempo drop. Then, at measure 700, there’s a signature change to 1/8, followed by a tempo change to 145.2 (Step) at measure 709, and a signature change back to 4/4 at measure 710.
What’s happening?
- The Omnivocal window is closed.
- When playing the track from, for example, measure 690, everything works fine. All tempo changes and signature changes do what they’re supposed to do at the right time.
- I open the Omnivocal window and repeat the playback described in the previous point. The same result, but at measure 699 with the tempo drop to 147.857, Cubase crashes! Omnivocal isn’t even active at that point. There are no MIDI parts and no audio output. This applies to the entire stripped-down project, by the way.
I haven’t tested whether reconstructing my above description produces the same result.
But I have a completely stripped-down (backuped) project with only the Tempo track, Signature track, and Omnivocal track remaining. This repeatedly causes the same crash at the same position.
If necessary, I can submit this project folder as a zip file. And of course I’ve already set aside the crash dump file.
Please upload the crash dump file to this topic.

Nice try! Do you really believe I’d upload that kind of data to a public forum without being familiar with the content?
Maybe you should re-examine how online security works.
If you are on Windows you can download WinDbg and use it to analyze the crash report yourself. Look which module actually crashed and at the last calls on the stack.
I think for Mac there is also a way of checking a crash reoprt.

That’s a tip that can at least satisfy my curiosity.
Sorry if I came across as a bit blunt, but that was my preoccupation when it comes to sharing potentially private information.
After reviewing the dump, dividing by 0 seems to be the problem.
I got the following information directly and via .ecxr and !analyze -v (as far as I can tell, without any vulnerable information ):

If you now want to upload the file then Steinberg / Yamaha could load it into their debugger.
The crash is in Omnivocal for sure. @Martin.Jirsak

Yep. I received a message during the crash that Steinberg or a third-party VST developer would appreciate support in that regard. But it doesn’t say how. I can only find options for when I want support myself.
It’s especially confusing when Steinberg includes a Yamaha plugin, being “part of Yamaha” (or not?), which isn’t available any other way. It seems WE are the beta testers before a general release. No problem… but then let Steinberg/Yamaha also provide easy options so that people don’t care to report it.
So… the description is the beginning of this topic, and the files are waiting here for a secure delivery option. At least there’s an agreement with Steinberg regarding the secure handling of personal data.
The crashdumps are safe to upload here, only issue I can see is that they might see you using cracked software. There´s nothing personal in dumps..
