Modulation Matrix - mode combobox stay empty after dragging a modulator onto a knob

@Christoph-Hart Mode combobox stay empty after dragging a modulator onto a knob.

I haven't used it myself yet, but if I understand correctly, properties such as “Mode” are only hardcoded for certain things like “gain” modulation. For all other connections, you have to set them in advance using setMatrixModulationProperties.

@Oli-Ullmann oh very interesting indeed! I must look closely to this... The Matrix Modulation is such a beast to get right...

[ustk]

@Oli-Ullmann I seem to make it working. I'am doing it in the ModMatrix.setConnectionCallback CB, but it appears it should be a one time setting at init, right? No need to do it every time you connect, am I right?

@ustk
My understanding is that you only need to use setMatrixModulationProperties once, for example in onInit, to set up your system. However, I think it can also be used multiple times. I don't know for sure, though, as I haven't reached that stage with my plug-in yet. When I get to that point, I'll let you know if I have any information. :-)

Maybe I'll have time to play around with it a bit later this week and I'll let you know if I find anything. :-)

@Oli-Ullmann yeah that’s what I did and it works nicely. I presume we can call it in a dynamic parameter assignment system, but if only static, doing it once at onInit seems good enough

Cool, that's good to know. Thank you! :-)
