hahaha I think I figured out what it is, I guess Traktor is trying to read Maschine as a midi along with running through Maschine software. I gotta mess with some setting (according to a friend with the same issue in Serato) and it should end it.
You are running two midi devices on the same channel. Set the midi channel to a different channel in Maschine and you are all good.
Maschine can be triggered through other midi devices. In your case, your Z2 (which is probably firing midi on channel 16) Maschine is set to 'omni" out of the box. Set it to a chnnel that’s not being used in any Traktor maps and you are fine.
