Bug: Cakewalk Bombs Out on Unfreeze

[Jeremy Murray-Wakefield]

A very common crash (almost once-per-session) on my system is this:

• I unfreeze (not quick-unfreeze) a virtual instrument that is loaded into NI Komplete Kontrol, and Cakewalk instantly exits.

This can happen on any project, new or old.

I can't attach a sample project, because on reloading such a project, the problem goes away. i.e. I can save a project immediately before the moment of the crash, and upon reloading and retesting that saved project, the crash does not happen at that same point (although it might do so later on during that session), and so it appears to be a state that isn't captured within the project file. One thing I've noticed is that I've not yet had a crash if I mute the track prior to unfreezing. That might of course just be coincidence.

Happy to post this somewhere else, if this is not the right place.

Unfreezing reloads the synth into memory. If he app spontaneously shuts down it could be memory corruption from the synth.

That would make sense.

It reminds me that I've previously had issues with Komplete Kontrol with Ableton Live too.

I seem to remember I discovered some kind of bug whereby KK can mis-declare the size of the parameter block that gets saved, and that I found some workaround that involved toggling KK's FX chain window on/off and re-saving.

Thanks, you've pointed me in the right direction, I think.

Let me know if you can get a reproducible case with a project and we can follow up with NI.
