Hi Jeremy,
Interesting! Can you consistently reproduce it in Bitwig? If so, please send the instructions to info@fabfilter.com
Hopefully we can reproduce it! Also, don't forget to include your OS information and plug-in format.
Thanks in advance!
It just happened, I will try to reproduce and share a project, but here's what I do:
I have a complex project with probably 10 instances of Pro Q4.
I switch from a simple project I'm using to test, to the complex project.
On the complex project I "activate audio engine" and if I hit play DURING the activation I may get "Plugin crashed".
This hangs the entire Bitwig process and I have to kill.
I have "sandbox by vendor" selected.
Mac Sequoia 15.3
Bitwig 5.3 Beta 7
Pro Q4 CLAP
Just upgraded from 5.2.7 to 5.3.1, after opening a project all my FabFilter plugins crash and need to reload them one by one.
I downgraded to 5.2.7 again.
I suspect it is a problem with Bitwig.
im getting a similar issue with logic 11 on sequoia.
After having a thorough look at the problem it turned out to be an issue with CLAP in Bitwig.
We've been in contact with them and a fix is being worked on.
@Benji, as Logic doesn't use CLAP I doubt this is the same issue, so could you send us an email with a more detailed description of the problem so we can see if we can reproduce it?
hi - yep ive emailed support.
