Good morning

I have a question about the articulation feature.

I would like to use articulation in an external MIDI track

I can not use it.

Is this a bug?

I did some testing.

You can use articulation in the instrument track

However, articulation is not available for external MIDI tracks.

I attached the result as a photograph below.
