Has anyone successfully made a MIDI plugin show up in Digital Performer?

I am trying to bring up and test the ArpeggiatorPluginDemo inside Digital Performer 9.52, Mojave 10.14.6, JUCE 5.4.4.

As far as I can see, it does not show up as a plugin anywhere in DP.

My Projucer settings have the default AU directory (~/Library/Audio/Plug-Ins/Components), the built plugin is in there.

The Exporter setting for Architecture is “Default” - is that 64-bit? I believe DP 9.52 is 64.bit by default, and there used to be a checkbox to run it in 32-bit mode, but I can’t find it in the Finder > GetInfo anymore.

Any ideas?

I am also seeing this problem. My MIDI plugin does not show in DP/.

Running in the debug mode nothing comes up, where would the best place be to put a breakpoint that would get triggered during DP plugin validation process?

breakpoint in PluginProcessor constructor does not get triggered by DP validation process.

So it must be something in Projucer land i suppose??
