PanFlow causing immediate crash upon launch of saved project

Help & Support Bug Reports
1

I love PanFlow but I never get to use it, since it always crashes my sessions.

I’m trying to open a project which had a few instances of PanFlow across the tracks, but Ableton crashes upon launching. The only way I can open the project is by deleting the PanFlow audio unit from Components folder.

Here’s to hoping there’s an update soon which makes this thing useable, as it truly is a great plugin concept.

Thank you

still struggling with this issue

i only use AUs, so that’s the version installed,
which continues to crash every project
and prevents projects from loading which use instances of Panflow

the only solution which allows me to open my projects again,
is removing Panflow from my system entirely

here’s today’s crash report:

Thank you for sharing the crash-log.

Can you please make sure that you are using the latest version?

Also, are you able to check the VST/VST3 versions and see if you still have the same issue?
