JucePlugin_IsMidiEffect and 'aumi' AU Type (kAudioUnitType_MIDIProcessor)

Hi,

I’m trying to understand well the effect of the JucePlugin_IsMidiEffect flag for AU plugins.

Is there any host recognizing a AU MIDI effect that has no ‘aumi’ AU Type?
Can somebody confirm that Logic only displays plugins with AU Type ‘aumi’ in their MIDI FX slot?

Thanks much!
