Properly Support Multi Channel VST3 Plugins like WTAutomixer

[Chris Spiegl]

Dear Adobe & Community, I'd like to ask if Premiere Pro could implement propper VST3 Multi Channel Plugin support for things like WTAutomixer? This is supported in Audition and the plugin does "work" in Premiere Pro but there is one specific bug:

When adding the effect WTAutomixer into the Effects Rack of one specific audio Track and opening it, the plugins hows no tracks. Then as soon as playback starts & there is sound, a track appears in the WTAutomixer interface. This is how it is supposed to work.

Then when I add the WTAutomixer to another audio track effects rack it also works the same way.

However, when removing the plugin from one of the audio tracks, the corrosponding track in WTAutomixer does not get removed.

I tried this in Audition, there it works as expected. If the effect is removed from one of the audio tracks, it also gets removed from the WTAutomixer plugin interface.

I contacted the WTAutomxier support and they let me know that this is something that is in Adobes hands and the way they handle VST3 multi channel plugins. So, I hope this can be fixed and made so that it is similar to how Audition and other audio work stations handle these types of plugins.

Warm Regards,

Chris

Just want to point out this is also an issue for ambisonics workflows. Premiere seems to be fussy about mapping channels properly.

All multichannel VST2 plug-ins seem to have this issue as well. If I use the Aalto university Array2SH ambisonic plugin, Premiere Pro only recognizes one mono input and one mono sidechain input, where the plugin is supposed to have up to 16 inputs and 16 outputs.

I can try and request a 4-channel input and output from the Aalto Array2SH VST2 plugin, but Premiere just states that the effect "does not support" the requested channel layout. While in reality - it does support it; Premiere just doesn't detect the inputs and outputs correctly.
