Side-Chaining feature of VST not working

[Bishop1000]

Describe the bug
I want to use this forum to get to the creators/developers of MusE Sequencer. to ask (Beg) them to look into a bug that is causing MusE not to be able to display the native plugin interface of vst plugins. it reverts to a generic interface, but this interface doesn't have the i/o port setting to enable the control of input and output signals to enable features like Side-chaining in mixing. Its really frustrating. I spent so mush time familiarizing myself with this great DAW. Love the midi sequencer and the Drum editor. but without the ability to side-chain my hopes of using it as my go-to DAW will be killed before it got a chance to take a breath.

Manjaro Linux
Manjaro-Pipewire audio

Hello. The native interface should be working.
If you right-click on the synthesizer's icon in the Track List, a popup menu selects which interface to open.
Similar action for each item in an audio track's effect rack: Right-click to popup a menu.
What do you see there? Is "Show Native Synth GUI" grayed out?
See the following picture:

Tell me which VST plugins you are attempting to use.
I will download and test them and verify if they are OK.

Thanks.

The option for native gui is greyed out. Calf sidechain compressors and lsd any of the linux compressors. In Ardour when I add a sidechain compressor I can see in Catia, where an additional channel becomes available for routing to the sidechain input sensor channel of the plugin. However in Muse with the "show native gui" option greyed out... I only see the MusE generic gui and none of the options available creates this additional channel. Allow me to send some screenshots in my next email.

[Sorry my mistake I thought you were using VST plugins. But it's LV2.]

Calf LV2 plugin native interfaces require GTK-mm-2 and GTK+2 development files to be installed.
This issue comes up from time to time, and this is usually the reason.

From our README file:

      - LV2 Gtk2 User Interface support:
      
        Some LV2 plugins may provide a Gtk2 based graphical User Interface.
        To view them, the following is required (development files):
        gtkmm-2
         http://www.gtkmm.org
        gtk+-2
         http://www.gtk.org

I am not sure what you mean by "and lsd any of the linux compressors".
But note that if you meant the standard old LADSPA plugins, there never were any native interfaces for those.
All DAWs only show generic interfaces for those.

When I check the Calf Sidechain Compressor I see four audio inputs and four audio outputs
which can be routed using our routing system.

Caveat:
MusE currently has no way of routing the control outputs provided by a plugin.
In the case of Calf Sidechain Compressor, these outputs are "Input" "Output" "0-dB In" "0-dB Out"
"Gain Reduction" "F1 Active" and " F2 Active".
You can see their outputs in the Generic User Interface, but they cannot be used for anything.
Unfortunately this may mean reduced functionality of sidechaining - especially if it is desired
to send these outputs to another plugin.
On the other hand, the compressors may work just fine for you, if you can live with that caveat.
Routing of control outputs is something planned for the future.

Thanks for your assistance...

Hope that helps. Let me know if any trouble.

[Bishop1000]

Can anyone say if there are any developments in the pipeline to resolve the "Sidechain plugin connector"/ "input detector" plugin / native interface greyed out in plugins... issues in Ardour?
