The recent update to Microtonic seems to have fixed the issue where it crashed Cubase 9, but a similar issue is happening with Permut8. Just like with the Microtonic, it seems to happen on the first "read" operation, like switching patches. The DAW has a hard, instant crash (same as before). And just like before, if I trick it out and do something else first, it tends to be stable for a while. Anything I can do to help reproduce or detail further? I'm using on Mac OS 10.12.3, MacBook Pro 2016 quad core, running Cubase 9.0.10

I was not aware that any product other than Microtonic suffered from this problem, but I'll look into it asap.

I am not able to reproduce this problem. Would it be possible for you to strip down a project that exhibits this behavior (or start from an empty project), keeping just Permut8 and upload the project here as an attachment?

Also, do you get a crash report after the crash? If so, could you please copy & paste the contents (at least the first few pages) for us?
