Current slider value doesn't update after deleting a modulation connection

[Oli Ullmann]

@ustk
I've also encountered this problem and still need to deal with it. My idea:
Perhaps we can use ScriptModulationMatrix.setConnectionCallback. When a connection is removed , we can trigger the slider/knob with changed() to set the correct value.

I'll try this out tomorrow and let you know if it works. :-)

[dannytaurus]

@ustk I know this might be a big ask, but do you have a minimal example of this as a snippet?

[Oli Ullmann]

@dannytaurus
All you have to do is modulate something using a slider and then remove the modulation. This also happens with “normal” HISE modules and not just with ScriptNode stuff. I'm not at my computer right now, but I can quickly create a small snippet for you later.

[ustk]

@Oli-Ullmann The problem is that Component.changed() happens on the script callback level, but with matrix modulation, since the component is connected to the modulator via processorId & parameterId you can't have a script CB at the same time

@dannytaurus trying a little snippet...

Broadcaster?

@David-Healey Oh yeah why not... Still it seems to be a hacky solution to trigger a "force refresh" from a connection callback

[David Healey]

@ustk A broadcaster is never a hack, it's a power move

[ustk]

@dannytaurus Here's a snippet. I'm not using a matrix modulator but direct parameter modulation, but the problem is the same.

Remove the modulator when the value is low, you'll see that it stays low instead of jumping back to the knob value

It works for me with your snippet and the variant I suggested. Here is a snippet:

Here's how it works if you want to apply it to multiple sliders at the same time. No broadcaster needed!

[ustk]

@Oli-Ullmann Nice! Maybe it's not that hacky after all...

[Oli Ullmann]

@ustk
It would be nicer if it worked automatically, but it's not a big deal to do it manually. :-)

[dannytaurus]

@David-Healey Fixing the underlying issue is the real power move

[ustk]

@Oli-Ullmann Finally it doesn't work in the case you remove the connection from the target combobox.
In this case the target argument becomes "No connection" so you can't match the original target.

[Oli Ullmann]

@ustk
Oh, okay. Thanks for pointing that out! I don't use the ModulationMatrix UI element, which is why I haven't encountered this scenario yet. Hmm...

Here's an idea that should work:
When a connection is disconnected, you can check in the ScriptModulationMatrix.setConnectionCallback for each slider to see if it can be connected to at least one modulator. If so, fire the changed function, as this means that there is currently no modulation connection. That should work. Unfortunately, I can't test it at the moment.

PS. Use ScriptModulationMatrix.canConnect(String source, String target) to check if a connection can be established.

[Chazrox]

I don't know if this will help this situation specifically but I had an instance when knobs weren't updating after preset changes. Calling .updateValueFromProcesssorConnection() instead of .changed() worked for me. Also not sure if this works with modulation matrix stuff.

[Oli Ullmann]

@Chazrox
Still you have to get the right knob in the setConnectionCallback but a good idea. :-)

[Chazrox]

@Oli-Ullmann yeah that's my lack of mod matrix knowledge talking. ha
