I’m am suffering from a strange behaviour in vvvv: some files do not open in vvvv 7.0.
Please have a look at the GIF above.
The file was created in 6.7, and when I try to open it in 7.0, it doesn’t work.
What can I do?
Thank you very much!
any chance you can share that file with us?
oh, great! Thanks for having a look at it. Here it is: Dropbox
hm.. opens fine here in 7.0 and 6.7 with vl.fuse 1.0.3-beta8
in your gif we can see the console popping up when you open it in 7.0. whats the error showing there?
That’s the message:

I think that might be related to this IChannel interface seems to have a `internal` member now (2025.7.1-0136-g42c85d3d1e) · Issue #711 · vvvv/VL.StandardLibs · GitHub
But this, if it’s it comes from 7.1 vs 7.0 comparability.
In any case I would suggest to try clean up nugget folder, as I suspect naturally is some gamma 7.1 nuget in 7.0 folder…
have you tried with latest fuse version in 7.0?
@vincent.now Check which version of FUSE you are using.
Since the patch does not use Fuse nodes, but Fuse itself is connected, try disabling it.
Yeppp … that solved the problem. Uninstalling Fuse and reinstalling - it worked. That was really helpful — thanks a lot!

When you see an error of this type, it is almost certainly related to FUSE. By the way, it would be great to get a comment on what these monadic attributes are; I’ve been very curious about this for a long time.
The monadic value is something used by Channel in VL VL.StandardLibs/VL.Core/src/Reactive/Channel.cs at a6c0a5b88206437bd5699cafbf32d3c1349bd5e2 · vvvv/VL.StandardLibs · GitHub
Seems it’s something that allows VL to find connectable pins:
