Unsolved Program Changes with VST3

[Matt_SF]

Hello everyone,
I'm trying to use Program Change messages in a plugin to change presets. Although it's working fine in HISE and in a compiled VST2 plugin, it's not working in VST3 (didnt't test AU).
Is anyone using these successfully in a VST3 plugin, or am I missing something ?

Here's a simple snippet :

(You'll have to add some presets to test it)

Ah, I stumbled upon the post on Juce forum already but I thought of asking people here.
So no Program Changes for VST3.
Thanks @d-healey

@Matt_SF Please describe precisely what you are trying to do, the difference between the expected outcome and your observed outcome, and the mechanism by which you are doing so. I can then answer your question.

[Matt_SF]

@Dr-Bill I wanted to be able to send program change messages from the DAW to my plugin. It works with the vst2 version of the plugin but not the vst3.

[clevername27]

@Matt_SF Which DAW, and what specific action are you performing there? Please be as specific as possible.

[Matt_SF]

@clevername27 I simply tried to add Program change messages support to my plugin so it could change presets with these, either by sending a PC message from a hardware controller or from the DAW :

I only tested it with Ableton. It worked just fine using the VST2 version of my plugin but not the VST3.

@Matt_SF I'll check on it and get back with you. I was just working on program changes this weekend for VST3 and didn't seem to have a problem, but I will verify. (I'll probably post my UI code today for it.)
