As a first attempt to build a project and load in logic, I took the MidiDemo in the examples. In Projucer I changed it to an Audio Plugin. Then tried various options for the AU setup such synth, Midi in, Midi output, midi effect etc. In some cases the plugin will build as a 5k size component. In some cases it is 30m. The first goal was to get it to load as an audio plugin on the master fader so I can see if the midi routing options would allow the goal of having an audio plugin with its own midi controls connected. Open Logic Pro, rescan and also trash plugin cache and it rescans all plugins but the AUMidiDemo never shows up in the plugin list event though I put it in the correct folder.
Can anyone please suggest what I can try to get this demo to build as audio plugin AU and show up? All I need it to do is load in logic, identify external USB keyboards, and display incoming note on/off.
