Hello T.

I think there’s a little initialization issue with the omni filter’s messages in spat5.oper which prevent it from being properly controlled from outside. I have attached a demonstration patch for confirmation.
Also I have noticed that the spat5.oper_ object has a setting of 8 internals which can’t be modified by the message /internals. Is that a normal behaviour?

Thank you,
Philippe :)

Hi Philippe,

Indeed the omni filter issue has been reported like 5 min after I uploaded 5.0.2.
So sorry about that.
Here is attached a fixed spat5.oper.

As for spat5.oper_, I’ll have a look at it.

Here is now a fix spat5.oper_ : it avoids tons of spurious error messages + now has a @internals attribute
(similar to spat5.oper, this cannot be changed on the fly / via messages)

Let me know if that fixes your problems.

Hi T.,

first, thanks for the great update with spat5, so much amazing tools in one library !
About spat5.oper: we have the possibility to label the sources as it use to be in spat4 with “source name” I think.
In spat4 the name showed up in the viewer and the tab of the .oper, in spat5.oper it only shows up in the viewer and don’t reflect in the tab (it remains S1, S2…)
In a situation with many sources labeled, it can become tricky to find out who’s who in the tabs…
Am I right ?

Hi Damien,

Thanks for your message and your suggestion.
This is on my todo-list. (Along with tons of other features that used to be ‘fine’ in v4 and need to find their way to v5.)
That one is easy, so it should be ready soon.
