Modulator level broadcaster

[d.healey]

It would be nice to have a broadcaster that listens to a modulator's value. That way I could make a knob on my UI move when a MID Controller or LFO's value changes.

@d-healey I’ve been using a global cable in scriptnode to get an lfo level. Works very well except the cables disappear when reopening hise!

@DanH I don't see how this helps me

[DanH]

@d-healey well you can get the value of the modulator via scripting and move a knob on the ui. Unless I misunderstand your original post...

[d.healey]

@DanH I can go that already with getCurrentLevel(). What I'm asking for here is a broadcaster so I don't have to poll the value in a callback.

[Christoph Hart]

@d-healey I would have to poll it on the C++ side too and as long as you're polling on the UI thread there's not a huge performance hit.

[d.healey]

@Christoph-Hart That makes sense.

So the situation I have is I want to take the value of a modulator (LFO or CC) and scale it using a table on the UI and pass the result to one of the macro parameters of a scriptnode effect.

The catch is I want one table per scriptnode parameter so I can't just use the modulator's single table.

Do you have a suggestion for the best way to achieve this?

Currently I'm polling the modulator, scaling the value with the table, and passing the value to the knob, but since this is in the UI thread it doesn't work when the plugin interface is not visible.

[d.healey]

Is there a broadcaster that can listen to a modulator's intensity (not talking about LFOs) but things like CC modulators?

I tried attachToModuleParameter but best I can do is get the defaultValue knob's value.

[Christoph Hart]

@d-healey Intensity is not a parameter but a property of the modulator base class, but I think I can add a special case to it so you can use attachToModuleParameter() (like I'm already doing with "Bypassed").

@Christoph-Hart Yeah that would be great, thanks!
