Midi machine triggered by midi channel

Does anyone know what the behaviour is or should be when a track assigned to a midi machine is triggered by midi?

For instance…

I have midi channel 1 assigned to track 1
I have a midi machine on track 1 assigned to channel 15 and C1

I fire a C4 on channel 1. I should get… something on channel 15? A C4?

This appears to be the behaviour. Is there a way to get it to only fire the assigned note? or perhaps transpose a C4 down to a desired note? I’m trying to map a note to a different note, essentially.

Try note 0.

Notes 0-11 trigger Tracks 1-12 normally.

I didn’t find it in the manual yet.
I experienced it, it seems to work like AR and other Digis.
First external midi notes trigger tracks.

I didn’t try with the midi machines thought.
