AU plugin won't output MIDI notes

[emviveros]

Using Camomile 1.0.8 beta4 and Camomile 1.0.7 with same behavior, Mac compiled AU plugin won't output MIDI notes, only bypass the MIDI notes. VST3 output the MIDI notes normally.

Test compiled plugins to test
MAC_au_vst3_MIDIout.zip

I missed something?

Tested in Mac OSx 10.14.6, Ableton Live 10.

Hello,

In fact, I'm not sure you can create an audio unit that accepts and generates audio and midi. That's might be a limitation. If you don't use audio, the plugin should try to use the midionly options. Perhaps the type of the plugin should also be modified, https://developer.apple.com/documentation/audiotoolbox/1584142-audio_unit_types.

Thanks for response Pierre!

I tried to use midi only, but I can't do it work either in 1.0.7 and 1.0.8 Camomile in Ableton Live 10. All times I tried Live 10 crashs with AU, and return a fail message when tried to load the plugin in VST3 format similar to this.

All times I tried Live 10 crashs with AU,

Can you share the crash report and the new version of your plugin?

return a fail message when tried to load the plugin in VST3 format similar to this.

Does it fix your issue to follow the answer?

Indeed, it seems that MIDI only AudioUnit generates a crash in Live. The only thing I found about a MIDI only audio unit is the kaudiounittype_midiprocessor but it's not explicitly that it should be MIDI only with no audio at all... I'm still investigating this issue.
